Jet Diffusers | 3 / 16 Description The JSR is a circular multiple-cone diffuser, installed on a duct, and is used to supply air to large spaces. 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 air supply. The angle of the diffuser can be set between 15° and 30° depending on the required distribution direction.
/ 16 | Jet Diffusers Design The JSR is manufactured from galvanised sheet metal with a white powder-coated finish in RAL9010 or RAL9003 (30% gloss). The discharge adjustment deflection cone is integrated into the circular casing. The cone can be removed to ease the installation of the diffuser.
