LWZ 70/170/270 plus

The LWZ 70 - 270, as a central ventilation system, is well suited to supplying fresh air to entire apartments. Using the countercurrent flow system, it extracts thermal energy from extract air and uses this energy to heat up the incoming fresh air. Thanks to this innovative process, up to 90 % of the energy can be recovered. As a central ventilation device for living areas up to 290 m², the LWZ 270 unit has been designed as a slightly larger unit. In the process, an easy to change filter cleans dust particles from the air.
