The JSR is a circular multiple-cone diffuser designed to supply air to large areas.
The unit can be installed on the wall or ceiling.
The JSR is manufactured from galvanized sheet steel with a powder-coated finish.
The JSR is a circular multiple-cone diffuser designed to supply air to large areas. It has the option of being installed onto a THOR plenum box or directly onto a duct. The THOR plenum box is used together with air diffusers for pressure reduction, airflow balancing and sound attenuation as well as for measuring and adjusting the air flow.
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. The unit has the option of selecting a scattered distribution pattern or a concentrated distribution pattern. The concentrated distribution pattern can be set by rotating the diffuser 180°.
This unit can be mounted either on the wall or on the ceiling and is suitable for both heated and cooled 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. Other sizes are available in this range.

Round supply air wide-angle nozzle for large rooms, with adjustable blow-off nozzle made of galvanized sheet steel, powder-coated.A wide flow pattern (short air distribution range) or a narrow flow pattern (long air distribution range) can be set by rotating the nozzle 180°.The nozzle is suitable for wall or ceiling mounting. On-site assembly, mounted directly onto the pipe using blind rivets. If the nozzle is connected to a junction box, a straight flow path of 4 x the pipe diameter must exist upstream of the junction box.The nozzle can handle cooled and heated supply air. - Size: 200- Distribution pattern: Diffused distribution pattern- Surface finish: Signal white (RAL9003)- Air flow direction: Horizontal
