Square & Circular Adjustable Swirl Diffusers (SWA) are suitable for Supply of Cooled Air with a large temperature differential, making these units ideal for Fan Coil Units, VAV and VRF Systems.
Each slot has a manual adjustable direction blade to vary the air pattern. The rotating supply air pattern provides a high degree of induction making these diffusers well suited to supply of both warm and cool air. Also suitable for Extract/Return Air applications.
SWA diffusers are manufactured from Galvanised Steel.
Standard finish is RAL9010 or polyester powder coated to the customers colour requirement.
Plenum boxes are accessories for use with Grilles and Diffusers. They are designed to equalise the pressure profile within the box and hence provide an even velocity at the face of the Grille or Diffuser without the use of Equalising Grids.
