This mechanical device ensures ventilation and air renewal inside our home by sucking air from so-called “wet” rooms (bathroom, kitchen, toilet, laundry room, boiler room) and fetching fresh air through modular grilles installed on the openings of so-called “dry” rooms and passing through the unheeled distribution doors.

There are different types of CMV.

– Single flow: permanent renewal of indoor air
– Adjustable hydro: renewal taking into account the humidity level present in the home
– Double flow: suction in wet rooms, discharge to the outside, insufflation of fresh air previously filtered in the living rooms (living room, lounge, dining room, office, bedrooms)
– Dehumidifier: dehumidifies the ambient air by regulating the ideal humidity level of a home between 30% and 60%.

Since recent events, many people have realized the importance of the quality of the air contained in the home and the double flow solution is a very good technique to solve this phenomenon (among others). Because it is proven that we spend on average 80% of our existence inside premises (office, telework, residential home, etc.) and there is a finding that is more alarming because indoor air is 7 times more polluted than outdoor air and more than one in two homes located in France is “contaminated” by pollutants contained in the ambient air (humidity, pollen, volatile organic compounds, cleaning products, fine particles, CO2, etc.)

Whether it is new passive housing, or the renovation of individual homes or collective housing, double flow ventilation solutions such as the Zehnder brand make it possible to effectively meet the requirements of each situation.
