WOLF Living space ventilation CWL-2

Central mechanical ventilation

CWL-2

The CWL-2 is the most efficient and quietest of all the WOLF central mechanical ventilation systems and the most compact of its kind on the market. 

Compact, quiet and highly efficient

Barely audible ventilation system

The CWL-2 central mechanical ventilation unit is as quiet as a whisper thanks to cutting-edge technology. It supplies your home with fresh, filtered air almost soundlessly.

The CWL-2 is a highlight of the WOLF ventilation system rage and also sets new standards of efficiency: this sustainable appliance has a heat recovery rate of up to 99%, which slashes your energy bills.

You can choose between two CWL-2 WOLF variants with different output levels: the CWL-2-325 and the CWL-2-400.

Healthy air for a comfortable home


Clean air day and night

The CWL-2 ventilation system supplies your home with healthy air around the clock without you needing to open a window. Even at night, it provides a constant supply of fresh indoor air and so promotes restful sleep.

Optimised air humidity at all times

The CWL-2 extracts stale air and excess moisture and expels it outside to the benefit of your physical health and mental capacity. It also reduces the risk of mould forming. 

Ideal for allergy sufferers

The powerful filters efficiently remove dust, dirt and pollen from the supply air. This is both hygienic and a great relief to allergy sufferers in particular.
