SDF Fixed Blade Swirl Diffusers

Introduction
Waterloo Air Products range of fixed blade swirl diffusers presents an attractive and aerodynamically efficient alternative to conventional circular or square ceiling air terminals.
The diffusers are designed to produce a horizontal, radial air pattern with a turbulent, high induction jet characteristic and are ideally suited for applications with high heating or cooling differentials.
Manufactured from aluminium with press formed blades, the units are available in a range of six ISO sizes in either circular (type SDFC) or square format (types SDFS) and can be supplied complete with a duct mounting collar for easy assembly.
The steel duct mounting collar can be used as a means of fixing and supporting the diffuser from rigid ductwork, or alternatively, ceiling support brackets (supplied on request) can be fitted for use with flexible ducting.
