Weil McLain 510-312-279 Blower Wheel

The Weil McLain 510-312-279 Blower Wheel is a critical combustion component engineered specifically for VHE Series 1 through 3 gas boilers. For technicians troubleshooting draft inducer assemblies or airflow failures, this 5.72" x 2" stainless steel blower wheel provides the necessary corrosion resistance to handle high-temperature flue gases and moisture. Unlike standard galvanized wheels that often succumb to oxidation in high-efficiency systems, the SS blower wheel construction ensures long-term structural integrity and steady static pressure.

This genuine OEM Weil McLain part features a 5/16" bore, precision-balanced to minimize vibration and bearing wear on the motor shaft. It is a direct fit for HVAC inducer blower repairs, critical for maintaining the specific air-to-fuel ratio required by high-efficiency boilers. When performing a swap, verify the set screw position and housing clearance to ensure optimal CFM performance and quiet operation during the combustion cycle.

• Corrosion Resistance: High-grade stainless steel prevents premature rust-out in high-condensate environments.
• OEM Precision: Guaranteed 5/16" bore alignment for seamless integration with Weil McLain inducer motors.
• Enhanced Durability: Robust blade geometry maintains airflow stability under varying combustion assembly pressures.
• Optimized Performance: Specifically dimensioned at 5.72" x 2" for VHE Series requirements.

Is this wheel compatible with standard galvanized replacements?
While some technicians use the 510-312-322 (5-3/4" diameter) galvanized version, the 510-312-279 is the specified stainless steel blower wheel for environments where moisture and chemical corrosion from flue gas are present.

What are the symptoms of a failing Weil McLain blower wheel?
Usually, excessive vibration, "hunting" ignition cycles, or a "No Flame" lockout caused by insufficient airflow to the combustion air switch indicate a compromised or fouled blower wheel.

Does this fit all Weil McLain boilers?
No, this part is specifically designed for VHE Series gas boilers. Professionals should always check the unit serial number against the HVAC replacement parts manual to verify the correct bore and diameter.
