Swirl Air Diffuser

A swirl diffuser spins supply air as it leaves the face, inducing room air into the stream within a short distance. The result: rapid temperature equalisation, low velocity at head height, and performance that holds up in variable-load zones. Powder-coated sheet steel or aluminium faces to match the ceiling.

What is a swirl diffuser good at?

Mixing. Swirl vanes spin the supply air so it entrains room air within a short distance: rapid temperature equalisation and low velocity at head height, ideal for variable-load zones.
