The NKSD-R round-face swirl diffuser is designed for low- and
medium-pressure ventilation systems.
The NKSD-R diffuser features adjustable vanes (16 to 32 vanes,
depending on the product type) for setting the uniform air
flow direction as required. The diffuser is easy to install and
can be fitted with a plenum box. The round-face swirl diffuser
can be used in steady and variable air flow systems. The swirl
diffuser is installed flush with the ceiling.
When installed on the PRR-SD-R plenum box, they provide a
uniform air supply, while an insulated version of the plenum
box reduces the ductwork and air noise level.
All diffusers come with two fastening screws, M6x40 and
M6x100, a screw cap, a screw hole plug, and a self-adhesive
foam gasket.
