HydroAir Slimline suction wall fitting

This Balboa HydroAir wall fitting is part of the Slimline suction assembly. The suction grille screws directly into it, on the inside of the spa.

It is available in standard and long versions, depending on your installation. With its very thin flange, the long version works well on wooden spas. The standard version is suitable for spas with walls up to 20 mm thick.

The wall fitting can be screwed on using a straight adapter (1.5-inch or 50 mm), or an 90°-elbow adapter (1.5-inch or 50 mm).

The long version can also be fixed in place with a simple nut and glued directly to a 1.5-inch pipe.

Installation
You should install it with a gasket and also use silicone between the wall fitting and the interior wall of the spa.
