Air Controller

Adjustable 3/4 inch air controller for spa and jacuzzi pools, used to set the air rate drawn into the hydro-massage jets. Includes body, plastic nut and adjustable air regulator. It sits in the spa surround above the water line on the air line feeding the jets; turning the cap opens or closes the air path, from a soft flow to a vigorous bubbling massage. Fit one controller per group of jets so each seat can be adjusted separately, and mount it high enough that water cannot siphon back into the air line.
