VVKN-A-S Swirl Diffusers

The VVKN swirl diffuser with fixed blades is designed to provide effective and comfortable air distribution. The diffuser face is supplied with a radially aligned set of blades of various shapes which guarantee an even distribution of swirl supply air into the occupied zone. The VVKN swirl diffuser can be installed onto an air duct using a plenum box with a horizontal or vertical connection by a flexible circular tube or the SPIRO duct. The VVKN can be used for both supplying or extracting air. It can also be used for ventilation, as well as supply cold or warm air. 

The diffuser face is made of galvanised steel and has a powder-painted surface. It’s also possible to manufacture the diffuser from stainless steel AISI304 or AISI316. In the centre of the diffuser, there is a screw opening to enable mounting. The mounting consists of installing the plenum box to the ceiling using drawbars and mounting the diffuser face onto the plenum box using a centric screw which is included in the delivery.
