The unit provides controlled ventilation with air recovery, radon ventilation, removes moisture in the house and is also an effective tool for filtration of dust and various allergens, and helps to reduce the building's energy consumption. The basic principle of controlled ventilation is to bring fresh air into the house, which is heated through the walls of the recuperation heat exchanger and is then distributed to the living areas. Conversely, stale air is extracted from bathrooms, toilets and kitchen. It transfers its heat in the exchanger and, together with water vapour, CO2 and other pollutants, is discharged through the facade out of the house.
