VSR

Description


VSR is a swirl air diffuser with radially adjustable blades.
The diffuser is recommended for installations with constant or variable air flow and is intended for spaces with heights up to 16m. It is used for introduction of air.

The design of the blades, their radial arrangement and the swirl action determine a high level of induction rate.

The diffuser is equipped with a perforated plate positioned on the diffuser connection.

VSR is available in 2 configurations:

       VSR – manual operation

       VSR-T – thermal operation (thermal element)

Dimensional range:  Ø250, Ø315, Ø400, Ø500, Ø630.

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.
