The diffuser can be supplied with a plenum connecting 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.

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.
