VVKN-A-R Swirl Diffusers

The VVKN-A-R is a fixed blade swirl diffuser that allows comfortable air distribution. It is designed for installation onto an air duct using a plenum box with a horizontal or vertical connection by a flexible circular tube or the SPIRO duct. Available in different sizes, the VVKN-A-R can be used for air supply and extraction. It can be used for ventilation, as well as supply cold or warm air. The diffuser face is supplied with a radially aligned set of variously shaped vents. This can guarantee an even distribution of swirl supply air into the occupied zone. 

The diffuser face of the VVKN-A-R is made of galvanised steel. It’s also possible to manufacture from stainless steel AISI304 or AISI316. The surface is powder-painted with a white RAL 9003 paint by default, other RAL types can be applied upon request. The diffuser is most commonly installed onto a ventilation duct and is designed for easy installation.
