Decentralised mechanical ventilation

CWL-D-70

The CWL-D-70 decentralised mechanical ventilation unit is especially easy to install, making this WOLF model perfect for retrofitting and for modernisation projects.

Decentralised, flexible and easy to install

The WOLF CWL-D-70 is the decentralised solution in our mechanical ventilation range. This makes it ideal if, for instance, you only want to continuously supply fresh air to particular rooms. This compact, wall-mounted ventilation model can be used to full advantage in existing buildings as the unit is particularly easy and inexpensive to retrofit.

Healthy air in rooms of your choice


Ideal for allergy sufferers

The CWL-D-70 mechanical ventilation unit reliably filters pollen, dust and dirt particles out of the supply air. Allergy sufferers in particular will benefit from the fresh, allergen-free air produced by the decentralised ventilation system.

Improved output

The CWL-D-70 extracts stale air and excess moisture from your home’s interior. The excellent air quality will noticeably improve your concentration while also reducing the risk of mould damage.

Automatic control

The CWL-D-70 is equipped with an intelligent control unit and fully automatically supplies your home with clean, fresh air. The air quality also remains consistently high throughout the night.

Affordable, healthy and reliable

High efficiency

Low operating costs

The countercurrent principle makes the CWL-D-70 ventilation system extremely efficient. The integrated heat exchanger uses energy from the extract air to preheat the fresh air. This increases its efficiency and lowers the operating costs. Read more

Optimum airflow

The flow of supply air and extract air is always exactly identical in the CWL-D-70 decentralised mechanical ventilation unit. This prevents areas of low pressure or high pressure from forming in the ventilated interiors.
