Frequently Asked Questions

What does a spa air blower do?

Do all hot tubs have an air blower?

No. Some spas use only water jets that mix air through a venturi system. Spas that include a dedicated air blower produce stronger bubbles and a more intense massage effect.

How do I know if my spa air blower needs replacement?

Spa air blowers are commonly available in 1.0 HP, 1.5 HP, and 2.0 HP models. The correct size depends on the number of air jets and the plumbing length in your spa. Matching the horsepower of your existing blower is usually the best option.
