The K-Line+ 12.5" Silent EC Fan combines powerful 3200m³/h airflow with an acoustically treated cylindrical housing and energy-efficient EC fan technology, providing high-capacity ventilation with reduced operating noise.
Designed for demanding extraction and air-movement applications, this larger K-Line+ model delivers a maximum airflow of 3200m³/h through a 12.5" duct connection. It is particularly well suited to larger controlled horticultural environments where substantial airflow is required but fan noise needs to be kept under control.
Unlike a conventional inline fan installed inside a separate silencer, the K-Line+ combines the fan and acoustic treatment within one compact cylindrical assembly. This helps reduce the amount of additional ventilation equipment required while keeping installation straightforward.
At the centre of the unit is an electronically commutated EC fan. EC technology combines efficient motor operation with variable-speed capability, allowing airflow to be matched more closely to the requirements of the ventilation system rather than continually operating at maximum output.
Why choose the K-Line+ 12.5" Silent EC Fan?
- 3200m³/h maximum airflow - high-capacity ventilation for larger extraction and air-movement systems.
- 12.5" duct connection - designed for large-diameter ventilation systems where high airflow is required.
- Silenced construction - acoustic treatment is incorporated around the fan assembly to reduce transmitted operating noise.
- EC fan technology - electronically commutated motor design provides efficient, controllable airflow.
- Variable-speed capability - EC technology allows ventilation output to be adjusted when used with an appropriate compatible control method.
- Compact cylindrical design - combines high-output ventilation and noise reduction within a single inline unit.
- Straight-through airflow - installs directly into a compatible circular duct run.
- Suitable for extraction or air movement - can form part of intake, extraction and filtered ventilation systems when correctly specified.
- Ideal for larger environments - the 3200m³/h capacity makes this the higher-output option within the commonly available K-Line+ Silent EC Fan range.
- 12 units per pallet - useful for trade, project and commercial purchasing.
High airflow without a conventional bare fan housing
High-capacity ventilation fans can generate noise from several sources, including the motor, impeller, moving air and vibration transferred into the connected ductwork.
The K-Line+ is designed specifically as a silenced inline fan. The fan assembly sits within the larger cylindrical acoustic housing rather than using the compact exposed casing typically found on a conventional inline fan.
This construction helps reduce fan noise at source while maintaining a straight-through ventilation path. For installations where noise control is important, it can be combined with acoustic ducting, vibration-isolating connectors and correctly supported duct runs to further reduce noise transmission through the ventilation system.
As with any high-output ventilation fan, the K-Line+ should not be considered completely silent. Airflow noise will still depend on fan speed, duct diameter, restrictions and the design of the complete ventilation system.
Efficient EC fan technology
EC stands for electronically commutated. An EC fan uses integrated electronic motor control rather than the simpler motor technology found in many traditional AC ventilation fans.
One of the major advantages is efficient variable-speed operation. Instead of treating the fan simply as an on/off device, a compatible control system can reduce airflow when full extraction capacity is unnecessary and increase it as ventilation demand rises.
This makes EC ventilation particularly useful in controlled environments where airflow requirements change with temperature, humidity, lighting load, crop development and seasonal conditions.
3200m³/h maximum airflow
With a rated maximum airflow of 3200 cubic metres per hour, this 12.5" K-Line+ is intended for applications requiring substantial air exchange.
The quoted figure represents the fan's maximum nominal airflow. Actual airflow through an installed ventilation system will normally be lower because every component introduces resistance.
Carbon filters, long duct runs, bends, reducers, silencers, intake restrictions and compressed flexible ducting can all reduce the volume of air delivered by the complete system.
When specifying ventilation, the fan should therefore be selected according to the resistance and required operating airflow of the complete installation rather than simply matching the room volume to the fan's maximum free-air rating.
12.5" high-capacity duct connection
The K-Line+ 3200m³/h model is designed around a 12.5" nominal duct connection, placing it firmly in the high-airflow end of an environmental ventilation system.
Keeping the ductwork at the correct diameter helps minimise unnecessary static pressure and air velocity. Reducing immediately into substantially smaller ducting can restrict airflow and increase turbulence and noise.
For best performance, use appropriately sized ducting and fittings, keep the route as short and direct as practical, and avoid unnecessary tight bends.
Building a quieter ventilation system
A silenced fan can significantly improve the acoustic performance of a ventilation system, but the complete installation determines the final noise level.
- Use correctly sized ducting throughout the installation.
- Keep duct runs as straight as practical.
- Avoid crushing or heavily compressing flexible ducting.
- Use acoustic insulated ducting where further noise reduction is required.
- Support the fan and ductwork correctly rather than allowing their weight to hang from adjoining equipment.
- Use vibration-reducing connectors where structure-borne noise is a concern.
- Avoid unnecessary reducers and sharp bends.
- Ensure filters and other components are appropriately sized for the required airflow.
Correct system design can reduce turbulence, restriction and vibration while allowing the EC fan to deliver the required airflow at the lowest practical operating speed.
Using the K-Line+ with a carbon filter
The K-Line+ can be incorporated into a filtered extraction system using a suitably sized carbon filter and compatible ductwork.
The filter must be capable of handling the required airflow. An undersized filter can create excessive resistance, reducing extraction performance and potentially increasing airflow noise.
Remember that the fan's 3200m³/h rating is its maximum nominal airflow rather than a guarantee of 3200m³/h through a filter and complete duct system. Filter resistance should be considered when sizing the installation.

K-Line+ 12.5" Silent EC Fan FAQs
Is the K-Line+ 3200m³/h fan completely silent?
No high-output ventilation fan is completely silent. The K-Line+ uses a silenced construction designed to reduce operating noise, but the final sound level will also depend on fan speed, ductwork, filters, airflow restrictions and installation method. What does EC mean on the K-Line+ fan?
EC means electronically commutated. EC motors use integrated electronics to provide efficient operation and variable-speed capability. Can the K-Line+ EC fan be speed controlled?
EC fan technology is designed for variable-speed operation. The control method used must be electrically compatible with the specific fan and its control interface. What size ducting should I use with the 12.5" K-Line+?
Use ducting and fittings matched to the fan's nominal 12.5" connection wherever practical. Maintaining the correct diameter helps reduce unnecessary restriction, turbulence and airflow noise. Can the K-Line+ be used with acoustic ducting?
Yes. Acoustic insulated ducting can be used as part of a low-noise ventilation installation and can help reduce noise transmitted along the duct run. Can the K-Line+ be connected to a carbon filter?
Yes. A suitable carbon filter can be incorporated into the extraction system, but it should be correctly sized for the required airflow and its resistance should be considered when specifying the fan. Will I get exactly 3200m³/h through a carbon filter?
Not normally. The 3200m³/h figure is the fan's maximum nominal airflow. Filters, ducting, bends and other restrictions create resistance and reduce the airflow delivered by the complete installed system. Do bends in ducting reduce airflow?
Yes. Bends increase resistance and turbulence, particularly when they are tight or numerous. Keeping the duct route short and direct helps preserve airflow and reduce noise. Why use a larger 12.5" ventilation connection?
A larger duct diameter allows substantial volumes of air to be moved without forcing the same airflow through a much smaller cross-sectional area. Correctly sized ducting can therefore help reduce restriction and excessive air velocity. Can I reduce the K-Line+ into smaller ducting?
A suitable reducer can be used where necessary, but reducing duct diameter increases system resistance and may reduce airflow while increasing turbulence and noise. Keep the full fan diameter for as much of the system as practical. Can the K-Line+ be used as an intake fan?
It can form part of an intake or extraction ventilation system where its airflow, direction, duct size and control requirements are appropriate for the installation. How can I make a K-Line+ installation quieter?
Use correctly sized ducting, minimise sharp bends and restrictions, consider acoustic ducting, isolate vibration where practical and operate the EC fan at the lowest speed that still provides the required environmental airflow. Is the 3200m³/h K-Line+ suitable for larger controlled environments?
Yes. Its high maximum airflow makes it particularly suited to larger controlled horticultural environments and ventilation systems where a smaller inline fan cannot provide sufficient air movement. How many K-Line+ 12.5" fans are on a pallet?
The pallet quantity for this SKU is 12 fans.

High airflow with reduced fan noise
High-output ventilation can generate significant noise from the fan motor, impeller, airflow turbulence and vibration transmitted into connected ductwork.
The K-Line+ is designed specifically as a silenced inline fan. Its fan assembly is contained within a larger cylindrical acoustic housing rather than relying on the compact exposed casing found on many conventional inline fans.
This construction helps reduce fan noise at source while maintaining the straight-through airflow path required for an efficient ducted ventilation system.
For installations where acoustic performance is particularly important, the fan can be combined with insulated acoustic ducting, vibration-reducing connectors and correctly supported ductwork to further reduce noise transmission.
No high-capacity ventilation fan is completely silent. The final sound level will depend on fan speed, airflow, ducting, filters, bends, restrictions and the way the complete ventilation system is installed.
Efficient EC fan technology
EC stands for electronically commutated. EC motors use integrated electronic control to provide efficient operation and effective variable-speed performance.
This is particularly useful in controlled horticultural environments because maximum extraction is not necessarily required continuously. Ventilation demand can change throughout the day as temperature, humidity, lighting load and external conditions change.
With an appropriate compatible control method, the K-Line+ can be operated at a reduced speed when ventilation demand is lower and increased when additional airflow is required.
Running the fan only as hard as necessary can also help reduce airflow noise compared with operating a high-capacity ventilation system continuously at full output.
2300m³/h maximum airflow
The 10" K-Line+ provides a maximum nominal airflow of 2300 cubic metres per hour, giving it the capacity required for substantial extraction and air-exchange systems.
Maximum fan airflow should not be confused with the airflow that will necessarily be achieved once the fan is installed. Every component within a ventilation system introduces resistance.
Carbon filters, long duct runs, bends, reducers, silencers, intake restrictions and compressed flexible ducting can all reduce actual airflow.
When specifying a ventilation system, consider both the required air-exchange rate and the resistance created by the complete installation.
10" high-airflow duct connection
This K-Line+ model is designed around a 10" nominal duct connection, making it suitable for ventilation systems where substantial volumes of air need to be moved efficiently.
Maintaining the correct duct diameter helps minimise unnecessary static pressure and excessive air velocity. Reducing immediately into significantly smaller ductwork can restrict the system, lower airflow and increase turbulence and noise.
For best performance, use correctly sized ducting and fittings, keep the duct route as short and direct as practical and minimise unnecessary tight bends.
Suitable for filtered extraction systems
The K-Line+ can be incorporated into a filtered extraction system using an appropriately sized carbon filter and compatible ductwork.
Filter capacity is important. An undersized filter can create excessive resistance, significantly reducing airflow through the installation and potentially increasing fan and airflow noise.
The fan's 2300m³/h figure is its maximum nominal airflow. Actual airflow through a carbon filter and complete duct system will normally be lower, so the resistance of the filter and ductwork should be considered when sizing the system.
Getting the best performance from the K-Line+
- Use 10" ducting and fittings wherever practical.
- Keep duct runs as short and direct as the installation allows.
- Avoid unnecessary tight bends and reductions in duct diameter.
- Do not crush or heavily compress flexible ducting.
- Support the fan and ductwork independently and securely.
- Consider acoustic ducting where further noise reduction is required.
- Use vibration-reducing connectors where structure-borne noise is a concern.
- Match carbon filters and other ventilation components to the required system airflow.
- Use compatible EC speed control where variable airflow is required.
A well-designed ventilation system reduces unnecessary resistance and allows the fan to provide the required environmental airflow at the lowest practical operating speed.

K-Line+ 10" Silent EC Fan FAQs
What is the airflow of the K-Line+ 10" Silent EC Fan?
The 10" K-Line+ is rated at a maximum airflow of 2300m³/h. Is the K-Line+ 2300m³/h fan completely silent?
No. The K-Line+ uses an acoustically treated construction to reduce operating noise, but any high-output ventilation system will still produce some fan and airflow noise. What does EC mean?
EC stands for electronically commutated. This motor technology provides efficient operation and allows effective variable-speed control when used with an appropriate compatible controller. Can the K-Line+ 10" EC fan be speed controlled?
Yes. EC fan technology supports variable-speed operation, although the controller and control method must be compatible with the fan. What size ducting should I use with this K-Line+ fan?
Use ducting and fittings matched to the fan's nominal 10" connection wherever practical. Correctly sized ductwork helps minimise restriction, turbulence and excessive airflow noise. Can I use acoustic ducting with the K-Line+?
Yes. Acoustic insulated ducting can complement the fan's silenced construction by helping reduce noise transmitted along the ventilation system. Can the K-Line+ be connected to a carbon filter?
Yes. The fan can form part of a filtered extraction system when used with an appropriately sized carbon filter and compatible ductwork. Will a carbon filter reduce the 2300m³/h airflow?
Yes. A carbon filter creates resistance, so actual installed airflow will be lower than the fan's maximum nominal airflow. The amount of reduction depends on the filter and the rest of the ventilation system. Do duct bends reduce airflow?
Yes. Bends increase resistance and turbulence. Keeping the duct route as straight and direct as practical helps preserve airflow and reduce unnecessary noise. Can I reduce the fan into smaller ducting?
A suitable reducer can be used where necessary, but reducing the duct diameter increases resistance and can reduce airflow while increasing air velocity and noise. Can the K-Line+ 2300m³/h fan be used for intake?
Yes. It can form part of either an intake or extraction system where the required airflow, duct sizing and installation design are appropriate. How can I reduce ventilation noise further?
Use correctly sized ducting, minimise bends and restrictions, consider acoustic ducting, isolate vibration where practical and use compatible EC speed control so the fan does not operate faster than necessary. Is 2300m³/h the actual airflow after installation?
Not necessarily. 2300m³/h is the maximum nominal fan airflow. Filters, duct length, bends, reducers and other restrictions will affect the actual airflow delivered by the installed system. Is this fan suitable for larger controlled horticultural environments?
Yes. Its combination of 2300m³/h maximum airflow, 10" connection, EC technology and silenced construction makes it well suited to larger controlled environments requiring substantial ventilation. How many K-Line+ 10" 2300m³/h fans are on a pallet?
The pallet quantity for this SKU is 15 fans.
