Field Controls 46131800 Blower Wheel

The Field Controls 46131800 Blower Wheel is a critical replacement component engineered specifically for SWG-3 and SWG-4 Series Power Venters. Designed to maintain precise static pressure and optimal flue gas induction, this centrifugal wheel ensures the ventilation system operates within its designated airflow parameters. When a blower wheel accumulates excessive soot or suffers from structural blade deformation, it leads to motor strain and compromised combustion efficiency. This OEM replacement wheel restores factory-spec CFM performance, ensuring the side wall venting system effectively clears exhaust gases. Constructed for high-temperature durability, this wheel is balanced to minimize vibration, extending the service life of the power venter motor and housing. For contractors performing preventative maintenance or diagnosing draft inducer failure, replacing a worn wheel is essential for system safety and reliability in residential and light commercial oil or gas heating applications.

• Direct OEM Fit: Drop-in compatibility for Field Controls SWG-3 and SWG-4 models reduces field labor time.
• Optimized Airflow: Precision-balanced blades ensure consistent venting capacity and minimize mechanical noise.
• Heavy-Duty Construction: Built to withstand the thermal stressors found in high-efficiency power venting systems.
• Vibration Reduction: Balanced design prevents premature bearing wear on the inducer motor.
• Restored Combustion: Facilitates the exact draft pressure required for stable burner operation.

Is this blower wheel compatible with the SWG-4HD models?
Yes, the 46131800 is the standard replacement wheel for the SWG-4 series, including heavy-duty configurations, provided the motor shaft diameter matches the original specifications.

What are the signs that a blower wheel needs replacement?
Technicians should look for excessive harmonic vibration, visible stress cracks on the hub, or significant buildup that cannot be cleaned without compromising the balance of the wheel.

How do I ensure the new wheel is installed correctly?
Verify the set screw is seated firmly on the flat portion of the motor shaft and check for adequate clearance within the housing to prevent mechanical interference during high-speed rotation.
