space than standard solutions, which is very convenient when
they should not be prominent once concealed. This advantage
helps free up usable indoor area.
The FLX-PRO-PL plenum boxes are made from galvanized
steel sheet. Special versions made from stainless steel are available on
The FLX-PRI-PL is a version of this product with insulation made
from 9 mm thick rubber foam installed inside the plenum box.
All plenum boxes are fabricated with outward pressure welds.
The FLX-USZ EPDM rubber seal installed in the plenum box increase
the airtightness to class C as per EN 12237.
