Hot Tub Air Controllers
Here you will find all of our spa air controllers which are part of a hot tubs air Venturi system. They come in multiple sizes shapes and colours and in most cases individual parts can be bought such as just the cap or o-rings can be bought instead of having to buy the whole assembly.
Each jet in a hot tub has an air and water connection, as the water passes through the jet body a suction is created on the air side, this is called a venturi action. All the airline connections from each of the jets are connected to manifolds and then the air controller. The air controller controls the amount of air flow injected or drawn though into the hot tub.
