Air Supply Ultra 9000 Blower – 2 HP, 120 V (Part # 3920131)

Part Number: 3920131

Description

A premium spa air blower designed for quiet, efficient operation in portable spas and hot tubs. The 2 HP, 120 V model delivers strong air flow with low noise and vibration thanks to its advanced intake manifold and rubber-motor mounting system.

Compatibility & Fitment

  • Designed for spa systems requiring a blower with a 2″ tapered slip discharge connection.
  • Ideal replacement when the existing blower is noisy, low in output, or failing prematurely.
  • Suitable for installation in spas or hot tubs using 120 V power and needing up to a 2 HP blower.

Features & Specifications

  • Horsepower: 2 HP full output.
  • Voltage: 120 V, 9 amp draw typical.
  • Discharge connection: 2″ tapered slip fitting (no glue or clamps required for basic fitment).
  • Noise & vibration reduction features: rubber motor mount, redesigned intake manifold.
  • Includes a 4-foot amp cord and 4-pin plug for plug-and-play installation in many spas.

Installation Notes

Turn off power at the circuit breaker and lock out the circuit. Remove the old blower assembly and note mounting orientation. Disconnect the electrical plug and hose/air line from the discharge. Install the new Ultra 9000 blower aligning the discharge port with your spa’s air plumbing. Secure the blower to the base, connect the 4-pin plug or hard-wire if required, and ensure the air line is clean and free of obstructions. Restore power and test operation—listen for smooth, quiet air delivery and verify no flow restrictions.

Maintenance Tip

Inspect annually for loose mounting bolts, damaged air lines, or debris entering the blower intake. Clean the discharge hose/tray and check for vibration or increased noise. Replace the blower if output diminishes significantly or if unusual sounds develop, to maintain spa user experience and system longevity.
