The PRR plenum boxes connect the ductwork ends to the
NK-SWA 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.
