Square & Circular Fixed Swirl Diffusers (SWF) are ideal for Fan Coil Units, VAV and VRF Systems. 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.
SWF 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.
