Air Blowers for Swimming Pool & Spa

Add the therapeutic sensation of bubbling air jets to your pool or spa with a quality pool air blower. Air Supply of the Future and Balboa Water Group blowers push pressurized air through your pool's air injection system, creating the effervescent jet effect found in luxury spas and hydrotherapy pools. PST Pool Supplies stocks the most trusted blower models — including the Silencer, Ultra 9000, Galaxy Pro, and Comet 2000 — in 1.0 HP, 1.5 HP, and 2.0 HP configurations.

The Air Supply Silencer lives up to its name — precision-engineered for whisper-quiet operation, it's the top choice for residential spa installations where noise is a concern. The Ultra 9000 delivers high-volume airflow for larger air injection systems, while the Comet 2000 offers a rugged, thermally protected design for outdoor and commercial use. All models are available in 115V and 230V configurations and feature hardwire or AMP connector terminations for compatibility with standard pool/spa control systems. For matching parts and replacement components, browse our spa air blower parts collection. See Air Supply's full product line at Air Supply of the Future's official site.

Pool and spa air blowers should be installed at least 12 inches above the water line and protected from direct water exposure per NEC Article 680 requirements. All blowers in this collection feature thermally protected motors that automatically shut off if the unit overheats, providing a critical layer of protection for both the equipment and the installation. Pair your blower with our pool automation systems to integrate the blower into your timed equipment schedule for hands-free operation. The Association of Pool & Spa Professionals (APSP) recommends annual inspection of air blower seals and impeller housings as part of routine spa maintenance.

Shop pool and spa air blowers — and bring the bubbling luxury of a hydrotherapy spa to your own backyard.

Frequently Asked Questions

What does a pool or spa air blower do?
A pool air blower pushes pressurized air through a dedicated air line and into air injection jets built into the pool or spa floor and walls. This creates the bubbling, effervescent sensation of a hydrotherapy spa. Unlike water jets (which recirculate pool water through a pump), air blowers draw in ambient air, pressurize it with an impeller, and push it out through small air nozzles. The result is thousands of tiny air bubbles rising through the water — soothing for muscles and joints, and a popular feature in spas, therapy pools, and hot tub installations.
What size air blower do I need for my pool or spa?
Blower sizing depends on the number and size of your air jets and the total length of your air distribution line. For a standard 6–8 jet spa, a 1.0–1.5 HP blower is typically sufficient. For larger spas with 10+ jets, or pools with an air injection ring system, a 2.0 HP model like the Air Supply Ultra 9000 or Galaxy Pro ensures adequate airflow pressure to all jets simultaneously. If your air jets produce weak bubbling or uneven output, the blower is likely undersized. Contact our team with your jet count and plumbing specs for a sizing recommendation.
Where should a pool air blower be installed?
Per NEC Article 680, pool and spa air blowers must be installed a minimum of 12 inches above the maximum water level to prevent back-flooding of water into the blower motor. They should be positioned in a ventilated equipment area and protected from direct rain and splash exposure. All models in this collection use hardwire or AMP connector terminations — installation by a licensed electrician is recommended. A one-way check valve should always be installed in the air line between the blower and the jets to prevent water from flowing backward into the blower when it's not running.
What is the difference between the Air Supply Silencer and the Ultra 9000?
The Air Supply Silencer is engineered specifically for quiet residential operation — its sound-dampening design makes it ideal for installations close to living spaces, bedrooms, or neighbors. The Ultra 9000 prioritizes maximum airflow volume and is better suited for larger spa systems or pool air rings with many jets. Both are available in 1.0–2.0 HP variants and are thermally protected. If noise is your primary concern, choose the Silencer. If you need maximum air volume output for a large system, the Ultra 9000 is the better choice. Browse replacement parts for both models.
