High Volume Diffusers

Jet Nozzle Diffuser

The Holyoake JND diffuser has been specifically designed to supply large air quantities over long throws with the added benefit of directional control. Jet nozzle diffusers are perfect for supplying large spaces such as halls, airports, and swimming pools. The JND consists of a single orifice, which can be adjusted in all directions.

  • Simple installation.
  • Modern aesthetic look.
  • Adjustable core.
  • Directional control.
  • Long throws.
  • Mountable directly into the end of a circular duct, a plenum box, or into a wall or angled ceiling.
  • Rotating the core by 180° switches the diffuser into plume mode which increases the spread and diffusion of the supply air.
