VS is a diffuser with fixed radially arranged blades and a swirl air jet, used to introduce air.
The diffuser is recommended for installations with constant or variable air flow and is intended for spaces 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 product is delivered with fixing screw and masking cap.
Dimensional range: Ø125, Ø160, Ø200, Ø250, Ø315, Ø400.

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