Frequently Asked Questions
A spa air blower forces air into the spa's air plumbing system to create bubbles through the air jets. This produces the bubbling massage effect many hot tubs are known for and enhances the overall hydrotherapy experience.
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.
Common signs of a failing spa air blower include: No bubbles coming from the air jets, Loud humming or grinding noises, The blower not turning on, Weak or inconsistent airflow. If your spa previously had strong bubbles and they suddenly stopped, the air blower may need to be replaced.
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.
Yes. If water flows backward into the blower it can damage the motor. This is why most spa systems include a check valve in the air line to prevent water from reaching the blower.
A loud blower can be caused by: Worn motor bearings, Debris inside the blower housing, Airflow restrictions in the plumbing, A failing blower motor. If the noise continues to get worse, replacement may be necessary.
Many spa owners can replace an air blower if they are comfortable with basic electrical connections. However, if you are unsure about wiring or spa electrical components, professional installation is recommended.
No. An air blower simply pushes air into the spa plumbing. Some models have heated air features that warm the air slightly for comfort, but they do not heat the spa water.
