HydroAir Top Draw air valve

By twisting the cap of this air valve, you can adjust the flow of air sucked into the water jets by the Venturi effect, and the intensity of the massage. The valve connects to 1-inch pipe.

This type of valve is especially recommended for use in a concrete spa, when it is necessary to use venturi valves that suck in air from the top, not from the sides (which will be embedded in concrete).
