73997 Air Control Lever, Warm Grey
Air control valves, located on the spa’s bartop, allow the spa user to control/adjust the amount of air that is supplied to specific hydrotherapy jets in the spa. The amount of air is controlled/adjusted by a turn of the air lever. The more air, the stronger the jet pressure feels.
The force of the water pressure rushing through the individual jets in a Venturi effect inducts the air through the air valves. The air check valves located in the equipment compartment under the bartop provide the air intake for the air valves.
