Central ventilation:
efficient, quiet, space-saving.

Central ventilation unit with heat recovery. Incl. moisture recovery using an enthalpy heat exchanger. The ideal solution for new-build single-family homes, terraced houses or large flats. It makes it possible to comfortably ventilate and purge rooms without having to open any windows. There is no mould formation thanks to the intelligent ventilation function. And undesirable substances in the indoor air are detected. It ensures that the fabric of the building is preserved. It always ensures healthy, hygienic indoor air.

The design of the M Flex Air has a particular focus on compact dimensions. With a width of 53.4 cm and depth of 56.0 cm, the free-standing ventilation module fits easily into commercially available cabinet and kitchen units. M Flex Air combined with System M heat pumps is the perfect solution for a comprehensive heating, ventilation and cooling system. Particularly clever: various installation options mean that space can be saved in the boiler room or utility room.

The enthalpy heat exchanger recovers part of the air moisture contained in the exhaust air and can therefore provide a remedy when the indoor air is too dry. The ventilation system is especially effective when combined with the Dimplex air distribution system Air 56.
