Regal Beloit 9438 Century Draft Booster Motor 1/50 Hp 115V Replaces Rheem Fasco A090 7021-5239

Product Description

The Regal Beloit 9438 Century Draft Booster Motor is a shaded pole replacement motor designed for use in residential and light commercial heating systems. It is a direct replacement for Rheem and Fasco units including the Fasco A090, part number 7021-5239, and compatible UE JA1M102 and Rheem 7 series applications. HVAC technicians rely on draft booster motors to move combustion air and flue gases through heat exchangers and vent systems. This motor keeps that process running efficiently and safely. The 9438 runs on 115 volts at 60 Hz and draws 1.1 amps. It is rated at 1/50 horsepower with a speed of 2975 RPM and delivers 90 CFM of airflow. The motor uses a single-phase shaded pole design, which is common in low-horsepower blower and draft inducer applications where simplicity and reliability matter most. The frame measures 3.375 inches in diameter, matching the standard 3-3/8 inch frame size used in many OEM inducer assemblies. Rotation is clockwise when viewed from the shaft end, which is the correct orientation for most Rheem-style draft inducer setups. The motor features sleeve bearings and an open air over enclosure type, suitable for the airflow conditions found in draft inducer housing applications. Insulation is Class B, and the maximum ambient temperature rating is 40 degrees Celsius. The service factor is 1.00 and the duty cycle is continuous, meaning this motor is built to run without interruption during normal heating operation. One notable feature is the included pilot light detector, which adds functional value for certain combustion monitoring setups. This part is a reliable, code-compatible replacement for failed or worn draft booster motors in gas-fired heating equipment.

• Replaces Fasco A090, 7021-5239, UE JA1M102, and compatible Rheem draft booster motors
• Includes pilot light detector for combustion monitoring compatibility
• Continuous duty rated with Class B insulation and 40 degrees Celsius maximum ambient temperature
