The 315mm Galvanised Steel Tee Piece is a rigid round ducting fitting designed to create a 90-degree branch in 315mm ventilation and air-extraction systems.
A tee piece allows one main duct run to be divided into two directions or two duct runs to be connected into a common line. Its three 315mm circular connections make it particularly useful when building larger extraction, intake and air-distribution systems.
Manufactured from galvanised steel, the fitting provides a strong and durable alternative to improvised flexible-duct junctions. The rigid construction helps maintain the shape of the airflow path while providing secure connection points for compatible 315mm ducting and ventilation components.
The large 315mm diameter makes this fitting particularly suited to high-airflow ventilation installations, including commercial horticulture, larger grow rooms, warehouses, workshops and other environments using 315mm round ductwork.
Why choose a 315mm galvanised tee piece?
- 315mm diameter - designed for compatible 315mm round ventilation systems.
- Three-way connection - creates a branch or junction within a ducting installation.
- 90-degree branch - useful for directing airflow into or out of a secondary duct run.
- Galvanised steel construction - strong, rigid and suitable for permanent ventilation installations.
- High-airflow applications - 315mm ducting is commonly used where substantial volumes of air need to be moved.
- Rigid connection points - provides a stable junction for connecting compatible ducting.
- Suitable for extraction or intake - can be incorporated into supply-air and exhaust-air systems.
- Professional installation - creates a cleaner and more durable junction than simply joining sections of flexible duct together.
- Compatible with ventilation accessories - useful alongside 315mm fans, silencers, filters, reducers, bends and ducting.
What is a ventilation tee piece used for?
A tee piece creates a three-way junction within a ventilation system. Air can travel along the main straight section while the perpendicular connection creates an additional branch.
Depending on the system design and direction of airflow, this can be used to divide one airflow into two duct runs or bring airflow from separate branches into a common duct.
This makes tee pieces useful when one extraction system needs to serve multiple areas, when air needs to be distributed to different locations or when several ventilation components need to connect into a larger duct network.
315mm ducting for grow rooms & horticulture
Larger indoor growing environments can require substantial airflow to remove heat, manage humidity and maintain effective air exchange. A 315mm ducting system provides considerably more cross-sectional area than smaller domestic-style duct sizes, making it suitable for high-capacity ventilation installations.
The 315mm tee can be used when dividing an extraction line between different sections of a grow room, combining suitable duct runs or constructing a more complex air-distribution system.
When designing a branched ventilation system, remember that airflow will not necessarily divide equally between branches. Duct length, bends, filters, silencers, restrictions and pressure differences all affect the final airflow through each route.
Why use rigid galvanised steel duct fittings?
Flexible ducting is convenient for connecting equipment and negotiating awkward spaces, but rigid fittings provide much greater structural stability at junctions and direction changes.
A galvanised steel tee maintains its shape under normal ventilation-system pressure and provides defined connection points for the three duct runs.
Combining rigid fittings with carefully installed ducting can also produce a tidier, more professional ventilation installation.
Installing a 315mm ducting tee
Plan the duct route before installation and determine whether the tee is being used to divide or combine airflow. Position the fitting so the connected duct runs can reach each opening without unnecessary bends or compression.
Connect compatible 315mm ducting or fittings to each connection and secure them using an appropriate method for the type of duct being installed. Flexible ducting is commonly secured with suitable duct clips or clamps, while rigid systems may use appropriate connectors and sealing methods.
For installations where air leakage needs to be minimised, seal the joints using suitable HVAC foil tape or another appropriate ventilation-system sealing method.
Plan branch airflow carefully
Adding a tee changes the resistance and pressure characteristics of a ventilation system. If one branch is considerably shorter or less restrictive than another, more air may naturally travel through that route.
Where controlled airflow distribution is important, the system may require suitable dampers or other balancing components.
Fans should also be selected according to the total resistance of the completed duct system rather than duct diameter alone. Carbon filters, silencers, long duct runs and multiple fittings can all reduce delivered airflow.
Compatible 315mm ventilation equipment
This tee piece can form part of a complete 315mm round ventilation system and can be used alongside appropriately sized equipment such as:
- 315mm rigid or flexible ventilation ducting
- 315mm inline extraction fans
- 315mm carbon filters
- 315mm acoustic silencers
- 315mm duct bends and elbows
- 315mm reducers and enlargers
- 315mm connectors and couplers
- Suitable duct clamps, clips and sealing materials
Always check the actual connection dimensions and fitting method of adjoining components before installation.

Yes. The side branch is positioned perpendicular to the main straight duct path, creating a conventional tee configuration. What is the tee piece made from?
It is manufactured from galvanised steel, providing a strong and rigid fitting for ventilation installations. Can I connect flexible ducting to it?
Yes, compatible 315mm flexible ventilation ducting can be connected and secured using suitable clamps or clips, subject to the dimensions and construction of the duct being used. Can it be used with rigid ducting?
Yes. It is designed as a rigid ventilation fitting and can be incorporated into compatible 315mm rigid duct systems using the appropriate connection method. Can I use this tee on an extraction system?
Yes. It can be used to divide or combine duct routes within a correctly designed extraction system. Can it be used for intake ventilation?
Yes. The same fitting can be used in suitable air-supply and intake duct systems. Will airflow split equally through both branches?
Not necessarily. Airflow distribution depends on the resistance of each duct route, including its length, bends, filters, silencers and other restrictions. Do I need to seal the duct connections?
Where minimising air leakage is important, joints should be secured and sealed using suitable ventilation-system clamps, foil tape or another appropriate method. Can I use this with a 315mm carbon filter?
It can form part of a ventilation system containing a 315mm carbon filter, provided the overall system is correctly designed and the adjoining components are dimensionally compatible. Can I use a tee to connect two grow-room extraction points?
Yes, a tee can be used to combine suitable duct runs, but the fan capacity, pressure losses and airflow balance of the complete system should be considered. Is 315mm ducting suitable for high-airflow systems?
315mm is a relatively large ventilation duct diameter and is commonly selected for systems designed to move substantial volumes of air. Actual airflow depends on the fan and resistance of the complete installation. Do I need a damper with a tee piece?
Not always. However, dampers can be useful where airflow needs to be balanced between branches rather than allowing it to divide according to the natural resistance of each duct route.

Its galvanised steel construction provides a strong, rigid junction for permanent and semi-permanent ventilation installations. Compared with trying to create a branch using flexible ducting alone, a purpose-made metal tee maintains a defined airflow path and provides secure connection points for adjoining ductwork.
The 250mm diameter makes this fitting well suited to medium and high-airflow ventilation systems used in grow rooms, commercial horticulture, workshops, warehouses and other indoor environments.
Why choose a 250mm galvanised tee piece?
- 250mm diameter - designed for compatible 250mm round ventilation systems.
- Three-way duct connection - creates a practical branch or junction within a ventilation system.
- 90-degree branch - the side connection runs perpendicular to the main duct path.
- Galvanised steel construction - strong and rigid for dependable ventilation installations.

What is a 250mm ducting tee used for?
A ventilation tee creates a three-way junction in a round ducting system. The straight section continues the main duct route while the side connection creates an additional 90-degree branch.
Depending on the direction of airflow and system design, the tee can be used to divide airflow between two duct runs or combine airflow from separate branches into one main duct.
This makes it useful for multi-zone extraction systems, air-distribution installations and ventilation layouts where several components or areas need to connect to a shared duct run.
250mm ducting for grow rooms & horticulture
Environmental control in larger indoor growing spaces often requires substantial airflow to remove excess heat and humidity while maintaining regular air exchange.
A 250mm ventilation system can accommodate considerably more airflow than smaller duct sizes when matched with appropriately sized fans and other equipment.
This tee piece can be used to create separate extraction or intake branches, combine suitable duct runs or build a more comprehensive ventilation network serving different parts of a growing area.
When branching a system, remember that airflow will not automatically divide equally. The length and resistance of each branch will influence how much air travels through it.
Rigid galvanised steel construction
Flexible ventilation ducting is useful for connecting equipment and routing air through difficult spaces, but junctions benefit from the additional stability provided by rigid fittings.
The galvanised steel construction allows the tee to retain its shape while providing defined circular connections for adjoining ductwork.
This makes it suitable for creating a tidy, robust and professional ventilation installation, particularly where ducting may need to be supported over longer distances.
Installing a 250mm ventilation tee
Plan the complete duct route before installation and decide whether the tee will divide one airflow into two branches or combine separate branches into a single line.
Connect compatible 250mm ducting or ventilation fittings to each opening and secure them using a suitable connection method. Flexible ducting can typically be secured using appropriately sized duct clips or clamps.
Where air leakage needs to be minimised, joints can also be sealed using suitable HVAC foil tape or another appropriate ventilation-system sealing product.
Support the surrounding ductwork correctly so that excessive weight is not transferred to the tee or adjoining equipment.
Understanding airflow through a tee junction
Installing a tee changes the pressure characteristics of a ventilation system. Air naturally follows the route offering the least resistance, so two branches connected to the same tee may carry different amounts of air.
A short, straight branch will generally present less resistance than a longer route containing several bends, a filter or other restrictive components.
Where airflow needs to be distributed accurately between different branches, suitable balancing dampers or other airflow-control components may be required.
Designing an efficient 250mm ventilation system
Duct diameter is only one part of ventilation-system design. The actual airflow delivered by a fan is affected by the total resistance of the complete installation.
Carbon filters, silencers, long duct runs, tight bends, reducers and junctions all introduce resistance. Keeping duct routes as short and direct as practical can help reduce unnecessary pressure losses.
When several branches are being connected to one extraction fan, ensure that the fan has sufficient capacity for the complete system rather than sizing it for an individual duct run.
Compatible 250mm ventilation equipment
The tee piece can form part of a complete 250mm round ventilation system and can be used alongside appropriately sized equipment including:
- 250mm flexible ventilation ducting
- 250mm rigid ducting
- 250mm inline extraction fans
- 250mm carbon filters
- 250mm acoustic silencers
- 250mm duct bends and elbows
- 250mm reducers and enlargers
- 250mm connectors and couplers
- Suitable duct clips, clamps and sealing materials
Always check the actual connection dimensions and fitting method of adjoining equipment before installation.

What is a 200mm ventilation tee used for?
A tee piece creates a three-way junction within a round ventilation system. The straight section continues the main duct run while the perpendicular connection introduces an additional branch.
Depending on the direction of airflow, this allows one main airflow to be divided between two duct routes or separate branches to be combined into a common duct.
This makes a 200mm tee useful when one ventilation system needs to serve different areas, when several extraction points need to be connected or when air needs to be distributed through multiple duct routes.
200mm ducting for grow rooms & horticulture
Indoor growing environments require effective air exchange to help remove excess heat and humidity. Larger grow rooms and higher-output ventilation systems often use larger diameter ductwork to accommodate the required airflow.
A 200mm tee can be incorporated into these systems to create separate intake or extraction branches, connect multiple ventilation points or build a more comprehensive air-distribution network.
It can be used alongside compatible 200mm inline fans, carbon filters, silencers and ducting to construct a complete ventilation system.
Rigid galvanised steel construction
Flexible ducting is convenient for routing air between ventilation components, but rigid metal fittings are particularly useful at junctions and direction changes.
The galvanised steel body maintains its shape and provides defined circular connection points for adjoining ductwork. This helps create a stable and tidy junction within the ventilation system.
Rigid fittings are particularly useful in permanent and semi-permanent installations where ductwork needs to be securely supported and connected.
Installing a 200mm ducting tee
Plan the complete duct route before installation and determine whether the tee will be used to divide one airflow into two branches or combine multiple branches into a single line.
Connect compatible 200mm ducting or fittings to each opening and secure the connections using a suitable method. Flexible ducting can typically be held in position with appropriately sized duct clips or clamps.
Where air leakage needs to be minimised, seal the connections using suitable HVAC foil tape or another appropriate ventilation sealing product.
Ensure surrounding ductwork is adequately supported so that excessive weight is not transferred to the tee or connected ventilation equipment.
Understanding airflow through a tee piece
Airflow does not necessarily divide equally when a ventilation system is branched. Air naturally follows the route presenting the least resistance.
A short and relatively straight branch may therefore carry more airflow than a longer branch containing several bends, a carbon filter, silencer or other restrictive components.
Where balanced airflow is important, suitable dampers can be installed within the branches to provide additional control.
Building an efficient 200mm ventilation system
The airflow delivered by a ventilation fan is affected by the resistance of the complete system. Duct length, bends, filters, silencers, reducers and junctions can all reduce the airflow achieved compared with the fan's unrestricted rating.
Keeping duct runs reasonably short and avoiding unnecessary bends can help reduce pressure losses. Where several branches are connected to one fan, the fan should be selected according to the requirements of the complete system.
A correctly planned system can provide effective air movement while avoiding unnecessary restrictions and excessive fan loading.
Compatible 200mm ventilation equipment
The tee piece can form part of a complete 200mm round ventilation system and can be used alongside appropriately sized components including:
- 200mm flexible ventilation ducting

The 315mm Galvanised Steel Straight Connector is a rigid round duct coupler designed for joining compatible 315mm ventilation ducting and components in a straight line.
Sometimes referred to as a 315mm duct connector, coupler, joiner or male connector, this simple metal fitting provides a secure connection point between two sections of compatible round ductwork.
Its galvanised steel construction provides a strong and rigid alternative to improvised duct joints, while the compact straight-through design introduces minimal unnecessary complexity into the airflow path.
The large 315mm nominal diameter makes this connector particularly useful in high-airflow extraction and intake systems used in larger grow rooms, commercial horticulture, workshops, warehouses and other ventilation installations.
Why choose a 315mm straight duct connector?
- 315mm nominal diameter - designed for compatible 315mm round ventilation systems.
- Straight-through connection - joins two compatible duct sections without changing airflow direction.
- Galvanised steel construction - strong and rigid for dependable ventilation installations.

- Suitable for extraction or intake - can be incorporated into exhaust-air and supply-air systems.
- Ideal for flexible ducting - provides a solid joining point between compatible sections of 315mm flexible duct.
- Useful with rigid systems - can also form part of a compatible rigid round duct installation.
- High-airflow applications - suitable for larger ventilation installations using 315mm ductwork.
- Professional connection - creates a cleaner and more secure joint than trying to overlap ducting sections.
What is a 315mm straight duct connector used for?
A straight connector is one of the simplest components in a round ventilation system. Its purpose is to provide a connection point between two compatible sections while maintaining the same nominal duct diameter.
It is particularly useful when joining lengths of flexible ducting, extending an existing duct run or connecting compatible components where a short straight coupling is required.
Unlike a reducer, bend or tee piece, the connector does not intentionally change the duct diameter, airflow direction or number of branches.
315mm ventilation for grow rooms & horticulture
Larger indoor growing environments often require substantial ventilation capacity to remove heat and humidity and maintain regular air exchange.
A 315mm round ventilation system provides a large cross-sectional area for moving air and is commonly paired with appropriately sized extraction fans, carbon filters and silencers in high-airflow installations.
Straight connectors allow longer duct routes to be assembled from separate sections while retaining the same nominal 315mm diameter throughout the connection.
Joining 315mm flexible ducting
When joining compatible flexible ventilation duct, position the end of each duct section over the appropriate side of the connector and secure it using suitable 315mm duct clamps or clips.
Where reducing air leakage is important, the joint can additionally be sealed using suitable HVAC foil tape or another appropriate ventilation-system sealing method.
Avoid crushing or excessively deforming flexible duct around the connection, as this can reduce the effective airflow area and create unnecessary resistance.
Maintain a smooth 315mm duct run
Straight duct routes generally create less resistance than installations containing unnecessary bends, reductions and compressed flexible ducting.
A purpose-made straight connector allows two compatible sections to be joined while maintaining a direct airflow path through the joint.
For the most efficient installation, keep duct runs as short and straight as practical and support the duct correctly to prevent sagging or excessive compression.
Why use a galvanised steel duct connector?
Ventilation joints need to remain secure while air is continuously moved through the system. A rigid galvanised steel connector provides a stable surface onto which compatible ducting can be secured.
Galvanised steel is widely used for ventilation fittings because it combines structural rigidity with a protective zinc-coated surface.
The result is a straightforward fitting suitable for both permanent and semi-permanent ventilation installations.
Compatible 315mm ventilation equipment
The straight connector can be incorporated into a wider 315mm round ventilation system containing appropriately sized components such as:
- 315mm flexible ventilation ducting
- Compatible 315mm rigid round ducting
- 315mm inline extraction fans
- 315mm carbon filters
- 315mm acoustic silencers
- 315mm tee pieces
- 315mm bends and elbows
- 315mm reducers and enlargers
- Suitable duct clamps, clips and sealing materials

The reducer transitions from a 250mm nominal connection to a 200mm nominal connection, making it useful when fans, carbon filters, silencers or sections of ductwork have different connection sizes.
Manufactured from galvanised steel, the fitting provides a strong and rigid connection suitable for extraction and intake systems in grow rooms, horticultural environments, workshops, warehouses and general ventilation installations.
Why choose a 250mm to 200mm duct reducer?
- 250mm to 200mm transition - connects compatible ventilation components with different nominal diameters.
- Galvanised steel construction - strong and rigid for dependable ventilation installations.
- Purpose-made size transition - provides a cleaner connection than compressing oversized flexible ducting onto a smaller fitting.
- Round ventilation fitting - designed for compatible circular duct systems.
- Suitable for extraction and intake - can be used in exhaust-air and supply-air systems.
- Useful for fan connections - adapt between compatible fans and different-sized ductwork.
- Useful for carbon filters - connect compatible filter and duct diameters where a size transition is required.
- Compatible with rigid or flexible systems - can form part of a wide range of ventilation installations.
- Compact design - provides the diameter transition within a relatively short section of ductwork.
What is a ventilation duct reducer used for?
Ventilation components are available with many different connection diameters. A reducer allows two otherwise incompatible nominal duct sizes to be incorporated into the same system.
This 250mm to 200mm reducer provides the transition required where one side of the installation uses 250mm round ducting and the adjoining section uses 200mm.
Common applications include adapting ducting to a differently sized fan, connecting a carbon filter or silencer with a different flange diameter, or changing duct diameter at a particular point within a ventilation run.
Reducer or enlarger?
Although commonly called a reducer, the fitting itself is not limited to one physical orientation. It simply connects a nominal 250mm round connection to a 200mm round connection.
Depending on the direction of airflow, it can therefore function as a reduction from 250mm to 200mm or as a transition from 200mm up to 250mm.
The effect on the ventilation system will depend on the direction of airflow, fan characteristics and resistance of the complete installation.
250mm to 200mm reducer for grow room ventilation
Indoor growing systems often combine extraction fans, carbon filters, silencers and ducting from different product ranges. Connection diameters do not always match, particularly when an existing ventilation system is being upgraded or modified.
A metal reducer provides a straightforward way to connect suitable 250mm and 200mm components while maintaining a secure, purpose-made airflow path.
It can be particularly useful when replacing an extraction fan, changing filter size or integrating existing ductwork with new ventilation equipment.
How does reducing duct diameter affect airflow?
Reducing a ventilation system from 250mm to 200mm decreases the available cross-sectional area through which the air can travel. This can increase air velocity and introduce additional resistance into the system.
The effect is particularly important in high-airflow installations. A ventilation system that has been designed around 250mm ducting may not deliver the same airflow if a significant part of the duct run is reduced to 200mm.
When selecting fans and ducting, consider the resistance of the complete installation, including reducers, bends, carbon filters, silencers and the total length of ductwork.
Installing a 250mm to 200mm duct adapter
Identify the 250mm and 200mm sides of the installation and check that the adjoining ducting or ventilation equipment uses a compatible connection arrangement.
Connect each side of the reducer to the corresponding nominal duct size. Flexible ducting can typically be secured using appropriately sized duct clamps or clips.
Where minimising air leakage is important, seal the connections using suitable HVAC foil tape or another appropriate ventilation-system sealing method.
Support the surrounding ductwork correctly so that the reducer is not carrying unnecessary weight from long sections of ducting or heavy ventilation equipment.
Plan duct reductions carefully
A reducer is an extremely useful component when different connection sizes need to be joined, but it should not automatically be used to make an undersized duct system compatible with a larger fan.
Long runs of smaller-diameter ducting can create considerably more resistance than an appropriately sized larger duct. Where possible, maintain the larger duct diameter through as much of the system as practical and introduce a size transition only where required.
This is particularly important with high-capacity extraction systems where unnecessary restrictions can significantly reduce delivered airflow.
Compatible ventilation equipment
The 250mm to 200mm reducer can be used when connecting compatible components such as:
- 250mm and 200mm flexible ventilation ducting
- Compatible rigid round ducting
- Inline extraction fans
- Carbon filters
- Acoustic silencers
- Air intake systems
- Duct bends, tees and straight connectors
- Existing ventilation systems being upgraded or modified
Nominal diameter alone does not always confirm that two components will connect directly. Check the actual fitting dimensions and male or female connection arrangement of adjoining equipment before installation.

250mm to 200mm Galvanised Reducer FAQs
What does a 250mm to 200mm duct reducer do?
It provides a transition between compatible 250mm and 200mm round ventilation components, allowing different nominal duct sizes to be connected. What is this ventilation reducer made from?
It is manufactured from galvanised steel, providing a strong and rigid connection within a ventilation system. Can I use it from 200mm to 250mm?
The fitting physically connects the two nominal diameters and can therefore be installed in either orientation where appropriate. The airflow implications of increasing or decreasing duct size should still be considered. Can I connect flexible ducting to this reducer?
Yes. Compatible 250mm and 200mm flexible ducting can be connected using appropriately sized clamps or clips. Can it be used with rigid ducting?
Yes, provided the adjoining rigid duct components have compatible dimensions and connection arrangements. Can I use this reducer with an extraction fan?
Yes. It can be used where a compatible extraction fan connection and the adjoining ductwork are different nominal sizes. Can I use it with a carbon filter?
Yes. A reducer can be used to connect a compatible carbon filter to differently sized ducting or ventilation equipment, provided the complete system is correctly designed. Will reducing from 250mm to 200mm reduce airflow?
A reduction in duct diameter introduces additional resistance and reduces the available cross-sectional area. The actual effect on airflow depends on the fan and the resistance of the complete ventilation system. Should I run the whole system in 200mm after the reducer?
That depends on the required airflow and fan specification. For higher-airflow systems, maintaining the larger duct diameter for as much of the run as practical can help minimise unnecessary resistance. Does the reducer need to be sealed?
Where minimising air leakage is important, connections should be secured and sealed using suitable duct clamps, HVAC foil tape or another appropriate ventilation sealing method. Can this reducer be used on an intake system?
Yes. It can be incorporated into compatible intake and supply-air systems as well as extraction systems. Is this suitable for grow room ventilation?
Yes. It is useful when connecting differently sized fans, filters, silencers and ductwork within grow room and indoor horticultural ventilation systems. Is a duct reducer the same as a duct adapter?
In ventilation systems, both terms are commonly used for fittings that connect two different duct diameters. This fitting transitions between nominal 250mm and 200mm round connections. Do I need to check the actual fitting dimensions?
Yes. Nominal duct diameter does not always describe the exact physical diameter or male/female connection arrangement, so adjoining components should be checked before installation.

The 315mm Galvanised Steel 90° Elbow is a rigid round ventilation bend designed to change the direction of 315mm ducting through approximately 90 degrees while maintaining the full nominal duct diameter.
Also known as a 315mm duct bend, ventilation elbow or 90-degree duct elbow, this fitting provides a purpose-made solution when a large-diameter ventilation run needs to turn around walls, ceilings, equipment or other obstacles.
The curved, segmented construction creates a smoother transition than attempting to force flexible ducting through a tight bend. This helps maintain a more consistent internal airflow path while producing a stronger and more professional installation.
Manufactured from galvanised steel, the elbow is suitable for 315mm extraction and intake systems used in larger grow rooms, commercial horticulture, warehouses, workshops and other high-airflow ventilation applications.
Why choose a 315mm galvanised duct elbow?
- 315mm nominal diameter - designed for compatible 315mm round ventilation systems.
- 90-degree direction change - routes ductwork around corners and obstacles.
- Rigid curved construction - maintains a defined airflow path through the bend.
- Galvanised steel - strong and rigid for permanent and semi-permanent installations.
- Full-size connections - maintains the same 315mm nominal duct diameter at both ends.
- Suitable for extraction and intake - can be incorporated into exhaust-air or supply-air systems.
- Ideal for large ventilation systems - useful where high-capacity fans and large-diameter ducting are installed.
- Professional installation - creates a cleaner and more stable corner than sharply bending flexible ducting.
- Compatible with 315mm ventilation equipment - suitable for systems using matching ductwork, fans, filters and silencers.
What is a 315mm ducting elbow used for?
A ventilation elbow changes the direction of a duct run without changing its nominal diameter. This allows a 315mm ventilation system to be routed around structural features, equipment and other obstacles while retaining a purpose-made airflow path.
Typical applications include taking ducting from a horizontal to a vertical run, routing extraction around a corner, turning ductwork towards an external vent or positioning ducting correctly between a fan, filter, silencer and outlet.
Because both connections remain at a nominal 315mm diameter, no separate reducer is required when the adjoining system also uses compatible 315mm components.
A better alternative to crushing flexible duct around corners
Flexible ventilation ducting can be bent around corners, but excessively tight bends can compress or deform the duct. This reduces the effective internal area and can create additional resistance and turbulence.
A rigid 315mm elbow maintains a defined internal passage through the change of direction, making it particularly useful where the duct route requires a substantial turn.
The result is also a neater installation, with the adjoining duct sections able to approach and leave the bend in the intended direction.
315mm elbow for grow room ventilation
Larger indoor horticultural environments often require substantial airflow to remove excess heat and humidity and maintain effective air exchange.
Large 315mm ventilation systems may include extraction fans, carbon filters, silencers and extensive duct runs. A rigid elbow allows these components to be connected even where the available space prevents the ductwork from continuing in a straight line.
This makes the fitting useful in grow rooms, propagation facilities, indoor horticultural spaces and other environments where high-capacity ventilation equipment needs to be installed efficiently.
Installing a 315mm ventilation elbow
Plan the duct route before installation and position the elbow where the system needs to change direction. Ensure there is sufficient space around the bend for the adjoining ductwork and any required clamps or supports.
Connect compatible 315mm ducting or ventilation components to each end. Flexible ducting can typically be secured using appropriately sized duct clamps or clips.
Where reducing air leakage is important, seal the joints using suitable HVAC foil tape or another appropriate ventilation-system sealing method.
Large-diameter ducting should be properly supported so that its weight is not transferred unnecessarily to the elbow, fan, carbon filter or other connected equipment.
How bends affect ventilation performance
Every change of direction introduces some additional resistance into a ventilation system. A 90-degree elbow will therefore create more resistance than an equivalent length of straight duct.
When designing a high-airflow system, consider the complete duct route rather than fan capacity alone. Carbon filters, silencers, reducers, tees, long duct runs and multiple bends all contribute to total system resistance.
Keeping the number of bends to a practical minimum and avoiding unnecessary changes in direction can help maintain airflow through the system.
Compatible 315mm ventilation equipment
The 315mm elbow can form part of a complete round ventilation system using appropriately sized components such as:
- 315mm flexible ventilation ducting
- Compatible 315mm rigid round ducting
- 315mm inline extraction fans
- 315mm carbon filters
- 315mm acoustic silencers
- 315mm straight connectors
- 315mm tee pieces
- 315mm reducers and adapters
- Suitable duct clamps, clips and sealing materials
Nominal duct size does not always describe the exact male or female connection arrangement. Check the actual dimensions and fitting style of adjoining equipment before installation.

The 250mm Galvanised Steel 90° Elbow is a rigid round ventilation bend designed to change the direction of 250mm ducting through approximately 90 degrees while maintaining the full nominal duct diameter.
Also known as a 250mm duct bend, ventilation elbow or 90-degree duct elbow, this fitting provides a purpose-made solution when a ventilation run needs to turn around walls, ceilings, equipment or other obstacles.
Its curved, segmented construction creates a controlled change of direction without requiring flexible ducting to be crushed or folded tightly around a corner. This helps maintain a more consistent airflow path while creating a stronger and neater ventilation installation.
Manufactured from galvanised steel, the elbow is suitable for 250mm extraction and intake systems used in grow rooms, commercial horticulture, workshops, warehouses and other medium to high-airflow ventilation applications.
Why choose a 250mm galvanised duct elbow?
- 250mm nominal diameter - designed for compatible 250mm round ventilation systems.
- 90-degree direction change - routes ventilation ducting around corners and obstacles.
- Rigid curved construction - maintains a defined airflow passage through the bend.
- Galvanised steel construction - strong and rigid for permanent and semi-permanent installations.
- Same nominal diameter at both ends - maintains a 250mm duct size through the fitting.
- Suitable for extraction and intake - suitable for exhaust-air and supply-air systems.
- Useful in high-airflow systems - ideal where larger fans and ventilation components are installed.
- Better than a crushed flexible bend - avoids forcing flexible ducting through an excessively tight corner.
- Professional installation - creates a strong, tidy and purpose-made change of direction.
What is a 250mm ducting elbow used for?
A ventilation elbow allows a round duct run to change direction while retaining the same nominal diameter. This is useful wherever a straight duct route is not practical.
Typical applications include changing from horizontal to vertical ducting, routing an extraction system around a corner, directing ductwork towards an external outlet or positioning ducting correctly between fans, filters and silencers.
Because the fitting remains at a nominal 250mm diameter at both ends, it can be incorporated into a compatible 250mm system without intentionally reducing the duct size.
250mm duct elbow for grow room ventilation
Effective environmental control in an indoor growing area depends on moving sufficient air through the space. Extraction systems help remove heat and humidity while fresh-air intake contributes to regular air exchange.
Larger grow rooms frequently use 250mm ventilation equipment where substantial airflow is required. A rigid elbow allows the ductwork to change direction cleanly where the layout of the room prevents a straight run.
The fitting can be used as part of systems containing compatible 250mm inline fans, carbon filters, acoustic silencers and flexible or rigid ducting.
Avoid crushing flexible ducting around corners
Flexible ducting can negotiate gradual changes in direction, but forcing it through a very tight bend can compress the duct and reduce its effective internal area.
A rigid metal elbow provides a defined route through the corner, helping prevent the severe deformation that can occur when flexible duct is folded or crushed.
This can be particularly useful with larger 250mm ducting, where maintaining the shape of the ventilation route becomes increasingly important.
How does a 90° elbow affect airflow?
Any significant change in airflow direction introduces additional resistance into a ventilation system. A 90-degree elbow therefore creates more resistance than an equivalent straight section of duct.
The complete system should be considered when selecting a fan. Carbon filters, silencers, reducers, tee pieces, duct length and bends all contribute to the overall resistance the fan must overcome.
Keeping duct runs as short and direct as practical and avoiding unnecessary bends can help maintain airflow and improve the overall efficiency of the ventilation system.
Installing a 250mm ventilation elbow
Position the elbow at the required change of direction and ensure sufficient space is available for the fitting, adjoining ductwork and any clamps or supports.
Connect compatible 250mm ducting or ventilation components to each end. Flexible ducting can typically be secured using appropriately sized duct clamps or clips.
Where minimising air leakage is important, joints can additionally be sealed using suitable HVAC foil tape or another appropriate ventilation-system sealing method.
Support larger duct runs correctly so that unnecessary weight is not transferred to the elbow, fan, carbon filter or other connected equipment.
Building an efficient 250mm ventilation system
When designing a 250mm extraction or intake system, consider the complete airflow route rather than individual components in isolation.
A high-capacity fan connected to restrictive ductwork may deliver significantly less airflow than its unrestricted specification suggests. Keeping the correct duct diameter and reducing unnecessary bends, restrictions and excessively long runs can help preserve system performance.
Where a direction change is unavoidable, a purpose-made rigid elbow provides a controlled and repeatable way to route the ductwork around the obstacle.
Compatible 250mm ventilation equipment
The 250mm elbow can form part of a complete round ventilation system using appropriately sized components including:
- 250mm flexible ventilation ducting
- Compatible 250mm rigid round ducting
- 250mm inline extraction fans
- 250mm carbon filters
- 250mm acoustic silencers
- 250mm straight connectors
- 250mm tee pieces
- 250mm reducers and adapters
- Suitable duct clamps, clips and sealing materials
