Airmaster ring-type Jet Diffusers are highly suitable for delivering a high stream of air over long distances. Its ability to deliver an accurate airstream makes it suitable for spot cooling applications. Its angular movement allows the air stream to be delivered through a wide area of direction either in full jet position or in reduced jet position.
The Jet Diffusers nozzle can be adjusted 30 degrees upwards and downwards. Nozzle jet can be rotated 360 degrees by adjusting the mounting frame. Jet Diffusers can be fixed directly to the round ductwork.gasket is sealed around the back of the Jet Diffuser to avoid air leakage.
Jet Diffusers are suitable for large spaces or area with high ceilings, such as theatres, concert halls, gymnasiums, mall atriums, exhibition halls, etc. Multiple Jet Diffusers can be integrated in a single panel for large volumes of air. The design of Jet Diffusers allows for a long distance throw along with trajectory control.
Airmaster Jet Diffusers are also available with manual or motorized operation. For motorized operation, an actuator is provided to control the direction of the spigot.
Airmaster Jet Diffusers are available in various colours of client’s choice , that will suit the aesthetics of the area of application.
Airmaster Jet Diffusers are available from 160mm dia upto 400 mm dia. Jet Diffusers are generally installed on the walls. Jet Diffusers can be supplied with plenum box with round inlet as option.

Related products: Airmaster manufactures products such as  Drum Louvers ( also known as cylindrical jet throw diffuser) for supplying large volumes of air across long distances. The drum or cylinder can be adjusted 30 degrees upward or downward to direct the air in the desired direction. The drum louver has vertical blades to adjust the airflow in the horizontal direction as well.
For applications requiring ceiling mounted diffusers to handle large supply air volumes, we recommend round ceiling diffusers – with adjustable core.
