This section describes how to use the ComfoAir 70.
2.1 Product description
In case of ComfoAir 70, it pertains to a decentralized ventilation device with heat recovery for healthy, well-
balanced and energy-saving comfort ventilation. The device can thereby be used as single-room device
(exchanging the air in one and the same room) or with the help of a two-room connection as the mentioned
isolated application. Stale, polluting smell of air, for example, from kitchen, bathrooms, lavoratory(ies) is
thereby extracted and the same amount of fresh air is inserted in the living room, bedrooms and kids room.
An enthalpy exchanger, which can also transfer the moisture in addition to heat on the basis of the physical
properties, is used in the ComfoAir 70 for heat recovery. The case includes powder-coated steel sheet as
well as aluminium coverings in the colouring RAL9016. The internal lining, made from high-quality
polypropylene, takes care of the required heat insulation and the device noise protection.
ComfoAir 70 has two maintenance free 24 VDC radial fans with electronic commutation and external power
supply unit for power supply. By default, one filter each of the filter class G3 is used for outside air and the
exhaust air. Filters of filter class F7 can be optionally used in the pollen filter quality for the outside air.
With respect to production, there can be odours during the start-up of the device. These
odours are completely harmless and evaporate at the most after a week in operation.
