The PRR-SD-R plenum boxes connect the ductwork ends to the
NKSD-R round-face vane swirl diffusers in low- or medium pressure
ventilation systems. A plenum box stabilizes the air
supply, providing uniform air flow rate before the air enters
the diffuser.
The ductwork is connected to the plenum box
inlet port at the side or from above, depending on the product
type. The inlet port can be provided with a damper.
ALNOR fabricates plenum boxes lined with flexible and heat-resistant
9 mm thick rubber insulation mats. Custom plenum
boxes manufactured as per customer specifications are also
available.
