Sterling HVAC 11J31R04094-002 Fan Motor

The Sterling HVAC 11J31R04094-002 Fan Motor is a high-performance 120V 1/3HP CW Fan Motor engineered for heavy-duty commercial and industrial unit heaters. Designed as a direct OEM replacement motor, this Permanent Split Capacitor (PSC) unit operates at a nominal 1,075 RPM with a 5.8 Amp draw, ensuring consistent airflow in demanding environments. It features an Open Drip Proof (ODP) enclosure and a 1/2-inch diameter shaft, making it compatible with a wide range of Sterling and Beacon-Morris TF, QVF, and QVSF series gas-fired unit heaters. The motor includes an automatic reset thermal overload protector to prevent winding failure during high-static conditions and utilizes a 7.5 MFD capacitor for reliable startups. Built with a focus on torque and longevity, this unit heater fan motor provides the necessary static pressure to maintain optimal heat exchange for large-scale warehouse and garage heating systems.

• High-Torque Performance: The 1/3 HP rating delivers the necessary power for large-diameter fan blades in commercial unit heaters.
• Enhanced Protection: Built-in thermal overload protection prevents motor burnout by automatically cycling off during excessive heat buildup.
• Efficient Operation: PSC motor design coupled with a 7.5 MFD capacitor ensures lower energy consumption and reliable starting torque.
• Standardized Housing: Features a standard 48-frame equivalent diameter with an ODP enclosure for maximum motor cooling in high-ambient ceiling installations.
• OEM Compatibility: Replaces common part numbers including J31R04094-001 and McMillan OEM A0828B2842.

• What rotation is required for this model? This motor is designed for Clockwise (CW) rotation when viewing from the shaft end. Verify your fan blade pitch before installation.
• Does this motor include the run capacitor? While the motor requires a 7.5 MFD / 370VAC capacitor, it is always recommended to install a new capacitor during motor replacement to ensure optimal performance and speed.
• Which Sterling heaters is this motor compatible with? It is typically found in Sterling TF, QVF, and QVSF series heaters with capacities ranging from 175k to 400k BTU.
