Fasco D791 Motor
The Fasco D791 is a high-performance PSC condenser fan motor engineered for demanding outdoor HVACR applications. Operating at 208-230V and delivering 1/3 HP at a steady 825 RPM, this 48-frame motor is designed for technicians who require a drop-in replacement motor that balances efficiency with long-term reliability. Featuring a 5.6-inch diameter and a single-phase configuration, the D791 utilizes ball bearings for all-angle mounting, making it suitable for shaft-up or horizontal orientations. The electrically reversible rotation and thermally protected design ensure it can handle high-ambient temperatures up to 60°C. With extended studs and a 1/2 x 6.42-inch shaft, this motor provides the physical flexibility needed for various condenser units. Integrating a permanent split capacitor (requires a 5MFD/370V capacitor), the D791 offers consistent torque and effective heat dissipation for continuous duty-air over (OAO) operations.
Key Benefits
- Optimized Performance: The 825 RPM low-speed design reduces noise levels and extends the operational life of fan blades.
- Versatile Mounting: Includes extended studs on both ends and four tapped holes in the shell for all-angle mounting.
- Thermal Protection: Features internal automatic overload protection to prevent motor burnout during extreme summer head pressures.
- Reversible Rotation: Simple lead reversal allows for both CW and CCW rotation, making it a versatile HVAC replacement part.
- Industrial Build: Rolled steel construction and ball bearings provide superior mechanical stability compared to sleeve-bearing alternatives.
Common Questions
What capacitor is required for the Fasco D791?
This motor requires a 5 MFD / 370V run capacitor for proper startup and operation. Using an incorrectly rated capacitor can lead to overheating or premature failure.
Can this motor be installed in a shaft-down position?
The D791 is rated for shaft-up or horizontal applications. For outdoor shaft-up installations, ensure a rain shield is used to protect the open air over (OAO) enclosure from moisture.
Is this a multi-speed motor?
No, the D791 is a single-speed motor designed specifically for condenser fan applications where constant RPM is required for optimal head pressure control.
