1 linear sectored slot diffusers M ADEL The series linear diffusers are designed to combine the aesthetics with the technical performance. They can be mounted in false ceilings or suspended from the ceiling. They allow the formation of diffuser continuous lines, with active and inactive areas, without breaking the uniformity of the whole. They are suitable both for supply and return. By adjusting their blades, sectored each mm, it is possible to obtain a horizontal distribution of the air in one or the other direction or its vertical projection without change the volume of air. The diffusers admit a flow variation of % keeping the air stream stable. These diffusers can be used from, up to metres high and at a temperature differential up to º C. /
