The NCD round vane supply diffusers are compatible with
low- and medium-pressure ventilation systems as well as A/C
air supply and exhaust ducts. They can be used in steady and
variable air flow systems. The diffuser can supply air in the
horizontal or vertical direction at a temperature higher or
lower than the room temperature.
The diffusers are light-weight and easy-to-install products. The
diffusers can be installed with PRO plenum boxes or RM-NCD
mounting frames. When installed on the PRO plenum box,
they provide a uniform air supply, while an insulated version
of the plenum box reduces the ductwork and air noise level.
