Swirl diffusers with adjustable radial air pattern

Swirl diffusers

A swirl diffuser is an HVAC air distribution device discharging conditioned air in a high-induction swirling pattern. Its unique design rapidly mixes supply air with ambient room air, effectively maintaining consistent temperatures and air quality. These diffusers use fixed or adjustable vanes to impart powerful rotary motion. This strong swirl creates high turbulence, rapidly entraining room air. Efficient mixing minimizes stratification, reduces drafts, and prevents hot/cold spots, even in high-ceiling areas. Swirl diffusers offer excellent comfort and energy efficiency due to superior induction. They are popular for commercial offices, retail, industrial facilities, and high-ceiling spaces needing uniform air distribution and quick temperature equalization.
