The NKSD-CB swirl diffuser is compatible with low- and medium-pressure air supply systems and spaces with a maximum ceiling height of 4 m. The air is supplied through 24 radially arranged holes. A great advantage of this diffuser is excellent air distribution performance and low air flow noise.
The diffuser is designed for installation on ducts, plenum (expansion) boxes and as ductwork termination on suspended ceiling. The diffuser features a fixing screw hole in the centre. The diffusers are light-weight easy-to-install products and require no additional bracing of suspended ceiling panels. When installed on the PRW plenum box, they provide a uniform air supply, while an insulated version of the plenum box reduces the ductwork and air noise level. The NKSD-CD swirl diffusers come with installation screws.
