Swirl Diffusers - 17 Pages
Dependant on requirements of maximum volumetric flow,
noise level and installation situation, swirl diffusers are
available with or without discharge nozzles. Depending on
architectural demands the face can be circular or square.
Duct connection details for the type RFD swirl diffuser are
shown below.
For types RFD-...-UO or RFD-...-UD, the top entry plenum
box supplied includes the internal subframe. In this
configuration the diffuser face is held in position by a central
fixing bolt which has a decorative cap.
