The redesigned Model PD square perforated face ceiling diffuser is intended to be compatible with 3 main ceiling grid sizes 300 x 300, 500 x 500 and 600 x 600. It is offered in a variety of flange styles to suit most contemporary ceiling grid systems. Incorporated in the design is a hinged perforated face inner core, which has a retention cord fitted, but the core is also removable to allow complete access for both installation and maintenance.
Outer frame sections mitred with welded seams. Perforated faces fixed using pivot pin or clip in bracket arrangement.
The diffuser may be used for either supply or extract purposes. When used in a supply application a central disc is fixed to the rear of the inner core, which gives a 4 way horizontal discharge. For extract use no disc is fitted. To change the air pattern, internal deflection plates are fitted to the frame behind the perforated core to provide the required; 3 way, 2 way opposite, 2 way corner or 1 way discharge. By changing the air pattern the external visual appearance remains the same, which adds considerable aesthetic appeal to this type of diffuser.
