Aluminium Spot Jet Nozzle Diffuser

A spot jet nozzle is aiming made physical: a sphere in a ring, pointed by hand at whoever needs the air. The pattern stays tight over short-to-medium throws, which makes it the terminal of choice for theatres, call centres, control rooms and anywhere comfort is personal.

Common questions

What is a ball-jet diffuser used for?

Personal, directional air: theatre and cinema seats, control-room consoles, laboratory benches; anywhere a person sits still and wants the air aimed at, or past, them precisely.

Does the ball stay where it is pointed?

Yes: the sphere seats in its ring with enough friction to hold aim through cleaning and vibration, while still adjusting by hand.
