Product Description

The JND Jet Nozzle Diffuser has been designed to supply both cooled air and heated air in buildings and structures with large areas. Typically, you’ll find nozzle diffusers installed in Sports Halls, Airports, Shopping Centres, Indoor Markets

Due to the refinement of the air delivery via our Jet Nozzle Diffusers, they provide a very efficient method of air supply over long distances whilst still maintaining low noise levels. This makes them particularly suitable for use within premises with high ceilings where noise could soon become an issue for the occupants. These jet nozzle installations would include: Theatres, Auditoriums, Museums, Concert Venues, Lecture Halls and Exhibition Centres.

The airflow pattern produced by the HVAC Jet Nozzle Diffuser is fully adjustable in any direction. In our standard Jet Diffusers, this is a manual operation and airflow can be set to meet your specific requirements. We also offer an automated model with electronic actuators, making adjustment of the jet diffuser an easy task from a more convenient location. This is particularly suitable where the nozzle diffusers are installed high up and the direction of airflow may need to be altered, perhaps due to seasonal variations within the environment.

Jet Nozzle Diffuser Selection

The JND Jet Nozzle Diffuser and the outer installation ring are manufactured from quality aluminium, creating a long-lasting, robust and low maintenance ventilation solution. They are available to order in a range of sizes including: 100, 125, 160, 200, 250, 315, 400 and 500, all offering variations on air delivery range, pressure drop and noise.
