Greenheck 1039438 Motor

The Greenheck 1039438 Motor is a high-performance 115V AC replacement motor engineered for precision in critical ventilation systems. Designed specifically for Greenheck SP and CSP series exhaust fans, this shaded pole motor operates at 1050 RPM with an 18W (19.2W nominal) output, providing consistent torque for light-commercial and industrial centrifugal ceiling exhaust applications. Featuring a Class B insulation rating and built-in thermal overload protection, the 1039438 ensures operational safety in continuous-duty cycles. This single-phase, 60Hz unit utilizes an extended thru-bolt mount for secure physical integration, maintaining the strict air-performance standards required for AMCA-certified equipment. As a direct OEM replacement part, it eliminates the compatibility issues common with universal motors, ensuring the fan wheel and housing maintain proper clearance and CFM delivery. For contractors servicing Greenheck SP-B200 or similar models, this motor is the standard for restoring factory-spec airflow and acoustic performance.

Key Benefits

• OEM Compatibility: Precision-matched for Greenheck SP fan motors and CSP cabinet series to ensure drop-in installation.
• Thermal Protection: Integrated auto-reset thermal overload prevents stator failure during high-static pressure conditions.
• Continuous Duty Rated: Engineered for 24/7 operation in commercial restrooms and mechanical rooms without premature winding degradation.
• Optimized RPM: Fixed 1050 RPM speed profile maintains the specific balance between static pressure capability and low Sone levels.

Common Questions

Is this motor compatible with speed controllers?
Yes, the Greenheck 1039438 is designed to work with standard solid-state speed controls often used in SP and CSP series fan assemblies.

Does it include the fan wheel or mounting bracket?
This SKU is the motor only. It utilizes the existing extended thru-bolt configuration for mounting within the fan's motor plate or power pack assembly.

Can this replace a motor with a different wattage in the same frame?
While the physical frame may fit, using a motor with incorrect wattage or RPM in a Greenheck centrifugal fan can lead to motor burnout or insufficient airflow. Always verify the model number on the unit nameplate.
