If you want an alternative solution to traditional, round valves for supply air, an elegant grille solution is available from NilAIR. The grid comes in silver anodised aluminium or in white powder coated aluminium.
The grilles are mounted in high supply air boxes that are typically placed in concrete floors or floor systems. They can also be installed in low supply air boxes in the ceiling, in a wall or under a wooden floor.
The boxes are available with 1, 2 or 3 connectors depending on the air volume required. The connectors fit NilAIR tubes Ø75 mm and Ø90 mm.
