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.
