VVKN-B-R Swirl Diffusers

The VVKN-B-R is a well-designed, tough and durable swirl diffuser with fixed blades. It provides comfortable air distribution when installed directly into the air duct. Available in different sizes, it can provide ventilation as well as supply cold or warm air. The diffuser face is supplied with a radially aligned set of variously shaped vents. These guarantee an even distribution of swirl supply air where it is required. The 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-B-R swirl diffuser is made of galvanised steel, but it is also possible to manufacture the diffuser 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.
