The Awenta WKA is an in-line axial duct fan that fits partially inside the ductwork. With no front panel, it disappears completely into the ventilation system. Designed for small to medium-sized rooms.
The WKA can be used for both extraction and supply air, and can be installed horizontally or vertically. The housing is made from UV-resistant ABS plastic with IPX4 protection.
The WKA is available in standard and timer (T) versions. The timer model features a built-in adjustable relay (3–30 minutes). Available in three sizes: 100, 125 and 150 mm. A KO100-21 connector is required for installation!

The WKA is a bi-directional fan — it works not only for extracting stale air but also for supplying fresh air.
This gives you real flexibility when designing your ventilation system.
The WKA uses ball bearings, meaning it can be installed horizontally or vertically with equal reliability.
The bearings won't wear out or start rattling over the years.
The Awenta WKA is rated for a 30,000-hour service life.
That can mean up to 15 years of trouble-free operation.
The WKA is a seriously powerful duct fan. The 150 mm version delivers up to 240 m³/h.
More than enough for larger rooms or longer duct runs.
The timer model features a built-in adjustable relay.
After the switch is turned off, it continues to ventilate for 3–30 minutes, ensuring all moisture is cleared.
A separate KO100-21 connector must be placed between the fan unit and the duct section for correct installation.
This must be ordered separately!
An inline duct fan is installed inside the ductwork rather than on the wall. With no visible front panel, it stays completely hidden — ideal for installation behind false ceilings or in loft spaces.
Yes! The WKA is a bi-directional fan, suitable for both extraction and fresh air supply.
The KO100-21 connector is a transition piece between the fan and the duct section. It is required for WKA installation and must be ordered separately in the correct size.
The 100 mm model is ideal for rooms up to 8–10 m² (105 m³/h). The 125 mm is recommended for 10–15 m² (205 m³/h). The 150 mm is best for rooms over 15 m² (240 m³/h).
The 100 mm model runs at 36 dB, while the 125 mm and 150 mm models both operate at 37 dB.
