PA air intakes provide fresh air intake or stale air outlet on the external wall in mechanical ventilation installations.
The assembly consisting of the 250 mm fixed sleeve and the 200 mm adjustment sleeve makes it possible to pass through walls 250 to 400 mm thick.
The sleeves are sealed in the masonry with a slight slope towards the outside (fixed sleeve Ø D2 on the outside of the wall and adjusting sleeve Ø D1 on the inside).
Provide an overlap of at least 20 mm between the 2 sleeves and an overhang of the sleeve on the inside of 30 mm minimum for the connection of the duct.
The aluminum grille simply clips onto the sleeve on the outside.
