Product Description

Swirl diffuser is generally used in high ceiling applications of up to 4.5m. The supply air rapidly mixes with the room air in a swirling pattern. Swirl diffuser is available in both fixed and adjustable blade pattern.  The design of swirl diffuser is aesthetically appealing and chosen by several architects.

Airmaster’s adjustable blade swirl diffusers gives user the liberty to control air flow by adjusting the blades individually.
