Airfoil’s Australian Made 20mm Polyurethane Foam Pre-Insulated Poly Board Return Air Plenum Box (PB-RAB-T) is a lightweight, fire-rated alternative to sheet metal, with an aluminium-coated exterior and durable epoxy varnish for enhanced insulation and reliability. The PB-RAB-T gathers return air from conditioned spaces and channels it back to the HVAC system, ensuring effective air circulation and ventilation.
With multiple Top Entry spigot placements, the PB-RAB-T efficiently returns air from behind the Return Air Grille. Designed to integrate seamlessly with Airfoil’s grille range, this plenum box is ideal for commercial settings with high thermal and acoustic requirements, exemplifying Airfoil’s commitment to superior Poly Board solutions.
