Lack of space and tight installation situations can make it difficult to install a mechanical ventilation system. For these scenarios, WOLF has developed the CWL-F-150 Excellent slimline ventilation unit. Thanks to its slender design and quiet operation, the CWL-F-150 Excellent can easily be fitted above the ceiling or in narrow recesses. With a maximum air flow rate of 150 m3 per hour, the unit is ideal for ventilating a small detached house.
This unit has a special feature – it uses countercurrent technology. Via a heat exchanger, supply and extract air are routed past each other along separate ducts, causing the warmer extract air to heat the supply air. This saves energy while also enabling an even, continuous air supply.
In summer you can circumvent heat recovery with the help of a bypass, allowing you to cool your house with pleasant night air. Furthermore, the unit is very easy to maintain and is also certified for passive houses.
