What does an air blower do in a hot tub or jacuzzi?

An air blower pushes warm air into the spa air line to create bubbles and an air-massage effect, improving comfort and user experience.

How do I choose the correct air blower size?

Selection depends on tub size, number of air jets, pipe length, and desired bubble intensity. Proper matching ensures strong and even air distribution.

Do air blowers need a check valve?

Yes. A check valve (and/or Hartford loop) helps prevent water backflow into the blower, protecting the motor and increasing safety.
