Available in two configurations, the AirClean central ventilation system impresses in the cold season with high heat recovery rates of over 80%. The very low power consumption of the supply and exhaust air units and the option to switch to demand ventilation in summer also saves a lot of energy. This ensures climate protection and living comfort. AirClean 180 (for small and medium-sized apartments) or AirClean 300 (for large apartments and houses) provide a comfortable climate fully automatically through smart, central ventilation control. Allergy protection is supported by filters against dust, pollen and other pollutants in the air intake. Used air, bacteria and viruses, but also humid sauna air or cigarette smoke are quickly extracted with decentralized LIMODOR exhaust air units. Heat recovery takes place via an efficient heat exchanger. Optional integrated silencers ensure whisper-quiet air exchange.
