Description
Dry inlet, mounted on the wall surface
AA131D is the dry-only version of the Aqua-Air surface mount: a 2″ vacuum inlet valve, a wall switch and a muffler on a single plate that screws to the wall face. Run 2″ pipe to it along the surface and you have a working inlet without cutting into the wall.
