Description
SW-R is a swirl diffuser with a square front plate, used to introduce or exhaust air.
The diffuser is recommended for rooms with heights between 2.6 and 4 m.
The design of the blades, their radial arrangement and the swirl action determine a high level of induction rate.
The diffuser can be used for installations with constant or variable air flow.
The diffuser has external dimensions 595×595 mm and can be made with 24 or 48 slots.
The diffuser is provided with individually adjustable black aluminum blades.
Air induction occurs rapidly due to the swirl action, resulting in a rapid change in temperature.
The product is delivered with the following elements: mounting bracket, fixing screw, screw cover cap and sealing gasket.

The diffuser can be delivered with a connecting plenum to the circular duct, with horizontal or vertical connection.
The plenum is provided with suspension elements (lugs) and bead roll on the spigot, for easy fixing of the flexible duct.
Optionally, a perforated damper can be mounted on the plenum connection to balance the air flow.
Adapter (plenum box)
The adapter is made of Z140 galvanized steel sheet and has 4 suspension lugs.
On request, the plenum can be insulated with 6 mm thick elastomeric rubber.
Perforated damper
The perforated damper is mounted on the adapter spigot and has the role of balancing the air flow.
The diffuser can be mounted in 600 x 600 mm T-bar false ceiling, continuous ceiling or suspended.
The fixing of the plenum diffuser is done by using a central screw screwed into the mounting bracket, positioned inside of the plenum box.
