Stainless steel ventilation supply valve design
The air supply valve DVIR is an extremely quiet air valve and is suitable for ventilating smaller rooms. The valve is made of brushed stainless steel. The supplied air is optimally mixed with the air in the room, resulting in draught-free refreshment of the air. The air volume can be variably adjusted by turning the adjustment scale into position.
