Sterling HVAC 11J31R04091 Motor

The Sterling HVAC 11J31R04091 Motor is a high-performance direct drive blower motor designed for precision air movement in critical heating applications. Engineered as a genuine HVAC replacement part, this 1/20 HP unit heater motor operates on a standard 120V single-phase power supply at 60 Hz. The Open Drip Proof (ODP) enclosure rating makes it an ideal fit for indoor environments, facilitating optimal heat dissipation through its internal fan system while protecting internal windings from vertical moisture. This shaded pole motor features a durable rolled steel frame and aluminum flange for superior corrosion resistance and structural integrity. Service technicians should note its specific compatibility with Sterling QVF100, QVEF100, and QVSF100 unit heaters, ensuring a drop-in OEM motor replacement that maintains factory airflow specifications. Its compact footprint and 1050 RPM rating provide the high-torque, reliable performance necessary for commercial HVAC maintenance and seasonal repairs.

• OEM Precision: Direct replacement for part number 382026, ensuring perfect alignment with original Sterling QV series heater brackets.
• Efficient Cooling: The ODP enclosure allows for maximum air circulation, reducing thermal stress on the motor during high-demand cycles.
• Rugged Construction: Rolled steel housing and aluminum components provide long-term durability in varied industrial settings.
• Simple Integration: Standard 120V wiring configuration simplifies electrical hookups for field contractors and service technicians.
• Certified Safety: Components are built to meet rigorous industrial standards for general-purpose HVAC motors.

Is this motor compatible with other unit heater brands?
While the 11J31R04091 is specifically designed for Sterling QVF100 and QVEF100 models, it may cross-reference with other units using the same horsepower and frame size; always verify shaft diameter and mounting patterns before installation.

Can this motor be used in high-moisture environments?
The ODP rating is intended for dry, indoor applications where moisture may drip vertically. For heavy wash-down or outdoor exposure, a TEFC (Totally Enclosed Fan Cooled) motor would be required.

What is the standard RPM for this replacement motor?
This motor typically operates at 1050 RPM, which is calibrated to deliver the necessary static pressure for standard unit heater heat exchangers.
