SW-2T Fan Type Swirl Ceiling Diffuser

ASLI SW-2T is a type of diffuser with fixed radially arranged air control blades. This unique type of slots provide high induction “vortex” air flow projecting horizontally from the face of diffuser. This swirling air flow produce a diffuse air distribution, with no stationary air jet resulting excellent uniformity of temperature in air conditioned space. SW-2T is suitable in area of high heat load where large quantities of cool air must be rapidly mixed with room air in a short time. The SW-2T series can also be use as a return and exhaust type device.
