The framed air intakes ensure the fresh air intake or the elimination of stale air on the external wall in mechanical ventilation installations.
Consisting of a galvanized steel frame with a strut and an aluminum grille, the air intakes on the frame are intended more particularly for the ventilation of technical rooms.
The frame also allows connection to rectangular ducts.
The frame is sealed in the masonry, the strut ensures perfect support of the frame during sealing. The grille is fixed by screws on the frame.
