Helios Fans KWL EC 60 Pro FFh

The Helios Fans KWL EC 60 Pro FF is a wall-mounted ventilation unit engineered for efficient single-room air exchange with integrated heat recovery. It features a high-performance aluminium plate heat exchanger with over 70% efficiency, combined with the latest EC motor technology for minimal energy use.

Designed with four selectable fan speeds, this unit provides both supply and extract air operation. It includes a built-in humidity sensor for demand-controlled ventilation, and the interior fascia is made from premium polymer. The fan housing, constructed from EPP, encloses two high-efficiency EC fans with fly screens and electrically operated external shutters made of high-grade steel. These shutters close tightly during idle periods and open automatically in case of a power failure.

The unit includes two G4-class filters made from electrostatically charged microstructured material to ensure clean air intake and exhaust. An optional F7 pollen filter (Ref. No. 9446) can be installed on the supply air side for enhanced air quality. Condensate is discharged directly outside via an external fascia with integrated drainboard.

Control is provided via the KWL BCU controller, which offers a clock timer and a range of programmable features.
