Mechanical ventilation unit
CWL-D-70

The decentralised ventilation solution that is suitable for both new build and modernisation.

Do you want to provide your house, apartment or just a single room with a continuous supply of pollen-free, fresh air while the windows are closed? Then the compact, decentralised CWL-D 70 mechanical ventilation unit is definitely the right choice for you – especially for building modernisation.

This unit has a special feature – it uses countercurrent technology. Supply and extract air are routed past each other in separate ducts, causing the warmer extract air to heat the supply air. This saves energy while also enabling an even, continuous air supply.

A steady airflow through your rooms also guarantees consistent and pleasant temperatures and prevents building damage due to mould. Special fine filters are inserted for allergy sufferers – making irritated eyes and blocked noses a thing of the past. During summer, the CWL-D 70 also makes use of the lower night-time temperatures to provide passive cooling of the interior.

Government subsidies may be available when installing ventilation in your home. To find out if your home is eligible, see our subsidies information page.

Unable to retrofit central ventilation in your home? You may find that a decentralised ventilation unit is the ideal retrofitting solution.
