RETURN AIR BOXES (RAB)
Airfoil’s Return Air Boxes are manufactured from 0.55 mm galvanised sheet metal to the highest standard. The design allows the box to return air from the face of the Airfoil grille. The Top Entry Model allows the sheet metal spigots to be placed opposite the open end of the box.
The Side Entry Model allows the sheet metal spigots to be placed at the side adjacent to the open end.
The Return Air Box is generally used in conjunction with Airfoil’s range of Return Air Grilles.
