Ideal solution for small apartments Energy efficient fan with constant flow rate Centrally filtered ventilation and extract air for optimum air quality (comfort) Ease of maintenance Pollutants are continuously removed from the living space Clear, logical operation Product details The LWZ 70 E ventilation unit has been specially developed for ventilation in apartments. A cross-countercurrent heat exchanger retains up to 90 % of the thermal energy from the extract air – energy that would be irretrievably lost with classic ventilation systems. Additional energy efficient features of the LWZ 70 E are its economical constant flow fans with integral control unit. Ventilation can be controlled in three stages via a remote control (essential accessory). The filters, which are easily replaced, clean the ventilation and extract air and ensure consistently high air quality. Thanks to its compact design, the LWZ 70 E can be very conveniently housed inside a kitchen wall unit.
