£13.50

The 200mm Galvanised Steel Tee Piece is a rigid round ducting fitting designed to create a 90-degree branch within 200mm ventilation, extraction and air-distribution systems.

Featuring three 200mm circular connections, the tee provides a simple way to split a main ventilation duct into two routes or combine separate duct runs into a common line.

Its galvanised steel construction creates a strong and stable junction within the duct system. Unlike an improvised flexible-duct connection, the rigid tee maintains a defined airflow path while providing secure connection points for adjoining 200mm ductwork.

The 200mm diameter makes this fitting particularly useful for medium to high-airflow systems in grow rooms, horticultural environments, workshops, warehouses and general ventilation installations.

Why choose a 200mm galvanised tee piece?

  • 200mm diameter - designed for compatible 200mm round ventilation systems.
  • Three-way connection - creates a branch or junction within a ducting installation.
  • 90-degree side branch - ideal for adding a secondary duct route to a main ventilation line.
  • Galvanised steel construction - strong and rigid for dependable ventilation installations.
  • Suitable for extraction and intake - can be incorporated into exhaust-air or supply-air systems.
  • Rigid connection points - provides a stable junction for compatible ducting and ventilation components.
  • Medium to high-airflow applications - useful with appropriately sized fans and ventilation equipment.
  • Professional duct installation - provides a cleaner and more durable junction than improvising with flexible ducting.
  • Compatible with 200mm ventilation equipment - suitable for systems containing 200mm fans, filters, silencers and ducting.

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
  • 200mm rigid ducting
  • 200mm inline extraction fans
  • 200mm carbon filters
  • 200mm acoustic silencers
  • 200mm duct bends and elbows
  • 200mm reducers and enlargers
  • 200mm connectors and couplers
  • Suitable duct clips, clamps and sealing materials

Always check the actual connection dimensions and fitting method of adjoining components before installation.

200mm Galvanised Tee Piece FAQs

What is a 200mm ducting tee used for?

It creates a three-way junction within a 200mm round ventilation system, allowing airflow to be divided between branches or combined into a common duct run.

What size ducting fits this tee piece?

It is designed for nominal 200mm round ventilation systems. Check the dimensions and connection style of adjoining equipment before installation.

Is the branch at 90 degrees?

Yes. The side branch is positioned perpendicular to the main straight duct path to create a conventional tee junction.

What is the 200mm tee piece made from?

It is manufactured from galvanised steel, providing a rigid and durable fitting for ventilation ductwork.

Can I connect flexible ducting to the tee?

Yes. Compatible 200mm flexible ventilation ducting can be connected and secured using suitable duct clips or clamps.

Can I use it with rigid ducting?

Yes. The fitting can be incorporated into a compatible 200mm rigid round ducting system using the appropriate connection method.

Can this tee be used with an extraction fan?

Yes. It can be used to create branches or combine duct runs within a correctly designed 200mm extraction system.

Can the tee be used for air intake?

Yes. It is also suitable for compatible air-intake and supply-air ducting systems.

Will both branches receive the same airflow?

Not necessarily. The airflow through each branch depends on its resistance, including duct length, bends, filters, silencers and other components.

Can I balance airflow between the branches?

Yes. Suitable ventilation dampers can be added where more precise control of airflow through individual branches is required.

Should I seal the connections?

Where reducing air leakage is important, secure the joints correctly and seal them using suitable HVAC foil tape or another appropriate ventilation sealing method.

Can this tee be used with a 200mm carbon filter?

Yes. It can form part of a ventilation system containing a compatible 200mm carbon filter, provided the overall system is correctly designed.

Can one fan extract through two branches?

Yes, provided the fan has sufficient capacity for the resistance and airflow requirements of the complete branched system. Airflow balancing may also be required.

Is 200mm ducting suitable for grow rooms?

Yes. 200mm ducting is commonly used in medium and larger indoor ventilation systems where higher airflow is required than smaller duct diameters can conveniently provide.
