Descrizione

The MSpa Bubble Generator (part no. B9300880/B9302138BU) is the high-performance blower motor designed to power your hot tub’s massage circuit. Located inside the motor unit, this component pushes atmospheric air forcefully and consistently through the micro-holes in the liner, creating the dense, enveloping flow of bubbles that characterizes genuine MSpa relaxation therapy. If your hot tub has lost intensity or the air massage does not activate, replacing the blower with this original spare part will instantly restore factory performance.

Quality original MSpa spare part, ideal for the following models: Tribeca, Toscana, Diva, Diva Plus, Duet, and Naval.

Mechanical Efficiency and Hot Tub Comfort

Precision engineering for uninterrupted relaxation:

  • Consistent, Powerful Airflow: The internal aluminum fan is calibrated to ensure optimal air pressure, distributing bubbles evenly around the entire perimeter of the tub while operating at 600 W.

  • Electromechanical Reliability: Developed with highly conductive copper windings and reinforced internal brushes, it offers excellent resistance to prolonged use cycles and frequent starts.

  • Acoustic and Vibration Insulation: The mounting flange includes rubber gaskets and cable glands specifically designed to dampen the motor’s background noise, keeping the surrounding environment quiet and relaxing.

  • Secure Connection: The integrated wiring is equipped with pre-insulated, transparent female Faston connectors, ensuring quick connection to the spa’s mainboard and complete protection against internal moisture.


Technical Specifications (Verified by the TempoStyle Team)

  • Standard Compatibility: Ideal for models in the MSpa collections—including the Lite, Comfort, Premium, and Frame series manufactured from 2018 onward—that use the internal compartment-mounted blower module.

  • Ultra-Lightweight, Compact Design: Designed to occupy minimal space in the motor compartment, making positioning and anchoring easier.

  • Structured Wiring: Includes main power and ground cables with protective heat-shrink tubing to withstand temperatures inside the technical compartment.


Installation and Safety Tips

  1. Electrical Disconnection: It is essential to disconnect the spa’s power supply by unplugging it before removing the motor’s protective cover.

  2. Duct Alignment: During installation, make sure the fan outlet is perfectly aligned with the air delivery sleeve to prevent pressure losses or motor overheating.

  3. Water Backflow Prevention: Make sure the spa air circuit’s non-return valve is intact, thereby preventing water from the tub from accidentally flowing back toward the blower’s electrical windings.


Frequently Asked Questions (FAQ)

1. Does the bubble generator also heat the air?This component is responsible exclusively for the air’s pressure and volume. The emitted air warms slightly and naturally due to the heat generated by the movement of the spa motor.

2. How can I tell whether my spa problem is caused by the blower or the electronic control board?If you activate the “Bubble” function on the display and hear a click from the control board but the motor does not turn, the blower is very likely worn or jammed. If no signal is detected, the problem may be with the control board.

3. Does this spare part include the screws for fastening it to the housing?No, the module is supplied as the motor body and wiring, using the existing mounting points and screws inside your spa’s technical housing.
