Fasco D121 Motor
For high-demand light-duty applications, the Fasco D121 Motor delivers consistent 1500 RPM performance in a compact 3.3-inch frame. This 1/70 HP shaded pole motor is a technician-grade replacement for evaporator fans, bathroom exhausts, and humidifiers. Operating at 115V with a 0.70 Amp draw, it features an Open Air Over (OAO) enclosure designed for continuous duty in air-moving applications. The CCW shaft end rotation and standard 1/4-inch diameter shaft ensure compatibility with original equipment manufacturer specs. Built with sleeve bearings and Class B insulation rated for 40°C ambient temperatures, this Fasco replacement motor provides reliable mechanical output in 1-speed configurations. The thermally protected design prevents winding failure during overcurrent events, while the 4-stud mounting pattern allows for flexible installation in tight HVACR housings. Use this direct replacement motor to restore airflow efficiency in residential and light commercial fan assemblies.
Key Benefits- Broad Compatibility: Direct replacement for several Fasco, Mars, and OEM 3.3-inch frame motors (Cross Ref: 7163-9727, JA2C354).
- Reliable Thermal Protection: Integrated automatic overload protection prevents overheating and extends service life.
- Flexible Mounting: Features extended studs on both ends and is compatible with belly band mounting.
- Quiet Operation: Precision-engineered sleeve bearings reduce vibration and mechanical noise.
What is the rotation direction of the Fasco D121?
This motor is configured for Counterclockwise (CCW) rotation when viewing the shaft end.
Can the mounting studs be modified for custom fits?
Yes, the 4-inch extended studs on each end can be cut down to fit specific housing depths if they are not required.
What are the typical applications for a 1/70 HP motor?
The D121 is commonly found in bathroom exhaust fans, range hoods, humidifiers, and small evaporator fan assemblies.
