JSR

The JSR is a circular multiple-cone diffuser for supplying air to large areas, which can be installed onto a THOR plenum box or a duct. A scattered distribution pattern (short throw) or concentrated distribution pattern (long throw) can be set by rotating the diffuser 180°. This unit can be mounted on either the wall or the ceiling, and is suitable for both cooled and heated supply air. The angle of the diffuser can be set at between 15 and 30° depending on the distribution pattern.

The JSR is manufactured from galvanized sheet steel with a powder-coated finish and is available in the following diameters: ø 200, ø 250, ø 315, ø 400 and ø 500.

The diffuser is installed directly onto the spiral duct and fixed with pop rivets. If the diffuser is fitted to a THOR plenum box, there must be a straight length, 4 times the duct's diameter, in front of the THOR plenum box.
