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-fixed 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. A new product has been added to Airmasters product line – Motorized swirl diffuser. It gives complete freedom for the user to adjust the airflow electronically without any hassle of using ladders to access the diffuser.
