Polyaire Linear Slot Diffusers are an attractive alternative to the ceiling or high sidewall supply diffusers. Slot diffusers can be installed individually in set lengths or in a continuous line. They can also be installed in any type of ceiling application.

The modules are available with a 20mm or 25mm Slot with the number of slots ranging from 1 to 8 slots and are further available as fixed or removable core. (Fixed Core - Model LSD-FC, Removable Core – LSD-RC.
The air pattern control is adjustable from the diffuser face and is achieved by means of an adjustable pattern control with each slot, enabling a full 180º air pattern adjustment. The suggested volume control should be from the main duct run take-off, or from a butterfly damper fitted to the inlet of the cushion head box.
Construction is from extruded aluminium and the recommended maximum length for each section is 3 metres. Standard finish is powder coat white while other finishes are available to suit the interior and architectural design requirements.

If your home has central heating and air, it contains a series of openings used to transfer air to and from the air conditioner and furnace. These openings are the grilles, vents, and registers. This is your guide to speaking like a pro when you talk about airflow within your home. In some applications, the diffuser may even be placed in the floor. In rare cases, linear slot diffusers may also take the place of an exhaust grill to return air from a room back to the heater or air conditioner. Slot diffuser units offer a number of advantages over traditional square or round diffusers. Fixed Blades Air Grill is a grill of a single set of fixed horizontal or vertical blades on 45° shape, frame blades are extruded aluminium alloy.
