The PRV plenum boxes connect the ductwork ends to the mesh
screen supply diffusers in high air flow 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.
