Diffusers
Ceiling, swirl, slot and jet diffusers for comfortable, draught-free air distribution
A diffuser is where an HVAC system meets the people in the room. Choosing the right type sets how far the air travels, how quickly it mixes with room air and how quiet the space stays.
Our range covers ceiling and swirl diffusers for offices and public buildings, slot diffusers for architectural ceilings, and jet nozzles for high spaces such as halls, airports and sports facilities.
