The WR fixed geometry round diffusers are used in the service sector and hospital settings. They comprise a front panel into which a series of stamp-formed deflection blades are inserted. Air is diffused by high induction swirling jets that rapidly equalise the temperature between the supply air and the ambient air.
These diffusers can therefore be used in variable flow systems with flow reduction down to 25%. They can also be used for air exhausting. They can be ceiling mounted or fitted onto exposed ducts.
The WR diffusers are made in two versions: WR 210 with downwards swirl flow and WR 230 with horizontal swirl flow diffusion collar.
