Room-specific supply air solution

Room-specific ventilation differs from central ventilation in so that each room that is air-conditioned has a separate device that can be used and adjusted per room. No ducting is required. We specialize in these systems.

Supply air valves are required to bring supply air into the house or a building. 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.

Energy consumption is the lowest in room-specific ventilation. Central air conditioning, even with heat recovery, consumes more energy because it does not take into account the stay in the rooms and the whole house air is exchanged, including empty rooms. For room ventilation, air is exchanged only in rooms where there are people, generally 2-3 rooms.


The cost of room-specific ventilation is only a fraction of the cost of a central system. On average, 2-4 supply air valves are needed, which cost less than €1000 in total. Central ventilation with ducting costs around €8000. A further advantage is that the cleaning and maintenance of supply air devices is considerably easier than the conventional supply air duct.


2030S Supply Air Valve

Mobair 2030S is a completely new concept for bringing the supply air into the room. The unique feature is heating of the incoming air with the warm air sediment at the ceiling. The valve has a 1.0 W fan which makes the power consumption very low. The patented grille brings in the supply air without draft.
