Ducted Residential Air Conditioning Systems – Types of Air Diffusers

A linear slot diffuser delivers the air around the edges of a room, instead of distributing the air from individual points in the ceiling. A speciality of this diffuser is that it can be used to return air as well to supply air.

One to four slot widths are used depending upon the volume of the air.

Some linear slot diffusers can create an air pattern to adjust to the shape of the room.

Jet Diffuser

Punkah Diffuser

Swirl Diffuser

The swirl diffuser is a special piece of equipment used in Air Conditioning units. The diffuser mechanism creates a turbulent supply of air in the immediate space surrounding it.
