Spa Air Blower Parts, Motors & Injectors

Restore the air injection function of your spa or hot tub with spa air blower parts from Waterway Plastics, Hayward, Hydro-Quip, Gentekk, and Horizon Spa & Pool Parts. PST Pool Supplies stocks the fittings, cords, switch kits, and plumbing components used in spa air blower systems, starting from $10.50.

Spa air blowers create the champagne-bubble effect in a spa by forcing ambient air through a dedicated air manifold and into the spa water via air injector fittings in the spa shell — separate from the water jet system. The key components in this collection: Waterway Top-Flo air injectors (3/8" barb, straight body, white) are the individual fittings installed in the spa shell that release air bubbles directly into the water — each spa may have 10–30 of these injectors distributed across the floor and walls. The 1-3/16" hole size required for installation makes them a standard size for most residential spa shells. Hayward IDXBLS1931 ABG Blower Switch Kit is the blower activation switch kit for Hayward above-ground heater-blower combinations — a complete replacement switch assembly when the original switch fails or becomes inoperative. Sweep elbows (90° direction change fittings) in 2" slip × 2" spigot configuration are available in both the Waterway standard sweep elbow and the more compact Gentekk compact sweep elbow — both Schedule 40 PVC, ASTM D-2466 rated. Sweep elbows are used in spa air blower manifold plumbing where the air line must change direction; the swept (large-radius) bend reduces turbulence and pressure drop in the air flow compared to a sharp 90° elbow. Blower cords connect the spa blower motor to the control system: the generic 115V male mini blower cord (48", 18/3 AWG) and the Hydro-Quip molded/lit blower cord (48", violet, with molded connectors) are the two most common cord types for residential spa blowers — the Hydro-Quip lit cord includes a built-in indicator light that confirms blower activation.

Air blower systems add a distinctly different hydrotherapy sensation than water jets — the thousands of tiny air bubbles rising through the spa water create a whole-body effervescent effect that many bathers find particularly relaxing. The most common air blower service issues are: failed air injector fittings (cracked or clogged with calcium deposits — replace individually without draining the spa if the spa water level is below the injector); failed blower motor (the blower produces no air or reduced output — blower motors are typically replaced as a complete unit); damaged blower cord (frayed or melted cord at the motor connection from heat exposure — replace the cord before attempting to operate the blower); and water in the blower (if the spa's check valve fails, water can back-siphon into the air line and reach the blower motor — always install or replace the air line check valve when servicing blowers). Always shut off spa power at the breaker before servicing any blower or electrical component.
