SW-3T Fan Type Swirl Ceiling Diffuser

ASLI SW-3T is a type of diffuser with fixed radially arranged curved air control blades. The curve profile of the blades and opening allow the air to be delivered horizontally with cyclone characteristic, which provide better induction “vortex” air flow than normal straight profile swirl diffuser. Room temperature and air velocity will be reduced effectively to achieve excellent uniformity of temperature in a comfort air conditioned space. It can be used as supply or return air device.
