Ceiling Swirl Diffusers

The ceiling swirl diffuser is made from galvanised sheet steel with manual adjustment of the air deflector blades which enables the discharge direction to be altered on site if necessary to give either horizontal or vertical throw.
The deflector blades can be preset at the factory to the desired direction to minimise adjustment.

The diffuser is designed to produce a rotary swirling air discharge which causes rapid induction of room air and decay of the supply air velocity.

The diffuser has a square surface plate which is powder coated to a standard RAL or BS colour - RAL 9010 as standard.
The deflector blades are black as standard but can be finished white to match the diffuser if required.

A side or top entry plenum box can be supplied and this incorporates the fixing arrangement necessary if single screw fixing is required.
Alternatively the diffuser can be supported on standard ceiling T-Bars and used as a tile replacer.

The plenum box is fitted with a perforated spreader plate/flap damper in the inlet spigot.

The diffuser can be used for supply or extract applications and is suitable for constant and variable air flows in room with heights of between 2.7 and 4.0 meters
