Greenheck 1039435 Fan Motor

For HVAC contractors maintaining commercial ventilation units, the Greenheck 1039435 Fan Motor is the essential service part for restoring specified airflow. As the direct replacement for 316480, this OEM Greenheck 115V motor eliminates the guesswork involved in field retrofits. This S33R352YB-19 model is a single-phase PSC motor engineered for high-static applications, drawing a precise 0.56 Full Load Amps to maintain electrical balance within the circuit.

Operating at a fixed speed of 1000 RPM with a power rating of 24.87 Watts, this motor is built with Class B insulation and dual thermal protection to withstand the high-duty cycles of exhaust and supply fans. Its yoke mount design (no base) and standard 60 Hz frequency ensure a drop-in fit for compatible HVAC blower motors and Greenheck ventilation fan assemblies. When replacing an aging or seized 316480 fan motor, this authentic Greenheck 1039435 provides the exact torque and dimensional alignment required to prevent vibration and premature bearing wear.

Key Benefits for Technicians:

• Perfect Compatibility: Verified 1039435 is a direct replacement for 316480, ensuring zero downtime during installation.
• Precision Engineering: Rated at 1000 RPM and 24.87W for synchronized performance with original fan curves.
• Enhanced Durability: Features dual thermal protection and Class B motor insulation for long-term service in commercial environments.
• Efficient Operation: Low amp draw of 0.56 A at 115V minimizes operational costs and heat generation.

Common Questions:

Is the 1039435 motor compatible with my existing fan wheel?
Yes, as a genuine Greenheck OEM motor, it maintains the shaft diameter and mounting configuration necessary to support original centrifugal or axial fan wheels, specifically replacing the legacy 316480 motor.

Does this motor require a start capacitor?
This is a Permanent Split Capacitor (PSC) motor; while most units of this type require a capacitor for operation, always verify your specific wiring diagram and the S33R352YB-19 technical data for field requirements.

Can I use this for variable speed applications?
This Greenheck fan motor is traditionally designed for single-speed 115V operation. For speed control, ensure your controller is rated for PSC motors to avoid winding damage.
