SWL/BF is a circular/square
diffuser with a rotating air pattern.
SWL/BF are supplied with a
plenum box with vertical or
horizontal connection. The box
can also be supplied with a
balancing damper for supply or
exhaust air.
The rotating supply air pattern
provides a high degree of
induction, making these diffusers
well suited to supply of both
warm and cooled air.
In addition the bellmouth exit
enhances the discharge air
pattern. For aesthetic purposes a
hinged core perforated diffuser
(suffix P) face plate can be fitted.
