Water Air Jet Mixer
Product Code: WAJ
Category: Spa Fittings
Concrete spa fitting — water/air jet mixer (venturi tee) for spa and jacuzzi pools, solvent-welded to a 1.5 inch pipe. Pressurised water from the spa pump passes through the venturi, draws air in from the air line and delivers the aerated stream to the jet nozzle for the hydro-massage effect. Cast one mixer into the spa wall behind each jet position, connect the top port to the air line fed by the air controller, and keep all jets on one pump within a 1.5–2 m pipe run of each other so they deliver evenly.

Frequently asked questions
How does the water/air jet mixer work?
Pressurised water from the spa pump passes through the venturi in the WAJ mixer, draws air in from the air line and delivers the aerated stream to the jet nozzle for the hydro-massage effect. One mixer is cast into the spa wall behind each jet position, solvent-welded to 1.5 inch pipe.
What does the air controller do?
The AC air controller sits on the deck at the head of the air line and lets the bather set how much air the venturis draw — from a soft stream to a strong bubbling massage — without touching the pump. The APB-1 air push button switches the spa pump on and off pneumatically, so there is no electrical switch near the water.
How are the jet nozzles adjusted?
The JN-1 directional flow ball fits inside the 1.5 inch pipe and turns to aim the aerated stream at the bather's back, shoulders or feet, so each seat can be tuned after the spa is filled. Screw the nozzles in after the tile finish is complete and set all nozzles on one pump to similar angles so the jets deliver evenly.
