The diffusers type RA are air feed elements with blades arranged at a tangent to promote air flow. They are suitable for fitting within false ceilings. Their excellent flow properties are retained when used as free-blowing air feed elements. The high secondary air induction rate also makes the air swirl diffusers suitable for systems supplying air at a variable rate (25 to 100%) and in assembly areas where a high degree of comfort is very important.
