Supply air valves are required to bring supply air into the house or a building. For a normal bedroom the amount of supply air required for two people is 2 x 20 m³/h or 40 m³/h. During cold and freezing temperatures the air volume can be reduced by about 40%. Even during the cold winter times, the Mobair supply air valves can bring the supply air inside without the feeling of draft, with good filtration and very low energy consumption.

Supply air valves are placed primarily in the bedrooms. It is also advisable to place a supply air valve in the living room especially if there is a fireplace. Energy consumption can be minimized when the supply air valve is kept operational only when the room is occupied.
