ROJSR 2000 Diffuser
Description
Systemair JSR circular multiple-cone diffuser. The diffuser’s throw
and distribution pattern are adjustable.
Function
The JSR is a circular multiple-cone diffuser for supplying air
to large areas, which can be installed onto a PER plenum box
or a duct. A scattered distribution pattern (short throw) or
concentrated distribution pattern (long throw) can be set by
rotating the diffuser 360°.
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.
Design
The JSR is manufactured from galvanized sheet steel with a
white powder-coated finish (RAL 9010-80) and is available
in the following diameters: ø 200, ø 250, ø 315, ø 400 and ø 500.
Mounting
The diffuser is installed directly onto the spiral duct and fixed
with pop rivets. If the diffuser is fitted to a PER plenum box,
there must be a straight length, 4 times the duct’s diameter,
in front of the PER plenum box.
