The WOLF solution for controlled ventilation in modern properties.

The compact installed height of the CFL units makes them ideal for use in suspended ceilings. Due to the components used, CFL supply air and extract air units meet the requirements of regulations on air hygiene in buildings, which are becoming increasingly significant.

With the help of the supply air units, rooms are constantly provided with filtered outdoor air in sufficient, infinitely variable amounts. At the same time, the efficient heaters ensure the required room temperatures.
With the CFL extract air units, a controllable amount of stale indoor air, laden for example with CO₂, is removed and expelled as exhaust air.
Use of the latest EC motor technology allows CFL supply air and extract air units to achieve a significant reduction in energy costs.
