Weil McLain 510-312-275 Ventor Motor

The Weil McLain 510-312-275 Ventor Motor is a high-performance 1/12 HP replacement draft inducer motor specifically engineered for Weil McLain series HE, HE II, and VHE boilers. Designed to maintain optimal combustion efficiency, this centrifugal blower motor operates at 3400 RPM on a standard 115V, 60Hz single-phase power supply. As an essential component for the safe expulsion of flue gases, the 510-312-275 ensures the pressure switch remains engaged by generating consistent static pressure. This unit features thermal protection to prevent winding failure during heavy-cycle operation in demanding hydronic heating environments. It is often identified as the primary motor component for the 510-312-312 and 510-312-317 blower assemblies. For technicians performing HVAC boiler repair, this OEM-spec motor offers a direct-fit solution, minimizing downtime and ensuring the boiler ventilation system meets strict operational parameters without the need for mounting modifications.

• Direct OEM Compatibility: Specifically designed for seamless integration with Weil McLain VHE, HE, and HE II series boilers.
• High-Speed Performance: Rated at 3400 RPM to provide the necessary airflow for efficient heat exchange and gas venting.
• Enhanced Durability: Includes built-in thermal protection and a C304L oval run capacitor (4MFD) to ensure stable electrical performance.
• Quiet Operation: Precision-balanced internals reduce vibration and noise throughout the heating cycle.

Is the 510-312-275 compatible with the obsolete 510-312-310 blower?
Yes, this ventor motor is the standard replacement part for the 510-312-312 and 510-312-317 blower assemblies, which are the recommended upgrades for older, discontinued venting units.

What are the electrical requirements for this inducer motor?
The motor operates on 115 Volts at 60Hz with a full load amperage (FLA) of approximately 1.1 Amps, making it compatible with standard residential boiler controls.

Does this motor include the run capacitor?
Most professional-grade 510-312-275 units are supplied with the required 4MFD oval run capacitor to ensure the motor starts under load and maintains efficiency.
