Lennox 25G21 Motor

Lennox 25G21 is a high-performance 460V 1/2 HP condenser fan motor engineered for demanding commercial and industrial HVAC applications. Operating at 1075 RPM with a single-phase power supply, this PSC motor (Permanent Split Capacitor) delivers the reliable torque and airflow required to maintain optimal head pressure in your condenser coils. Designed with a 48 frame size and a CCWLE rotation (counter-clockwise lead end), it serves as a direct OEM replacement for specific Lennox units, ensuring seamless mechanical and electrical integration. The vertical mounting position and NEMA-standard 1/2-inch shaft diameter allow for rapid field installation, reducing downtime during critical service calls. Built to handle 460V line voltage, this motor provides consistent duty-cycle performance in high-ambient environments without the efficiency loss common in generic aftermarket alternatives. For technicians troubleshooting Lennox fan motor replacement, the 25G21 offers the exact 12.5 MFD capacitor requirements and lead lengths needed to restore factory-spec air circulation.

• Precision Engineering: Designed as a direct OEM 1/2 HP HVAC motor to eliminate compatibility guesswork and mounting modifications.
• Optimized Airflow: The 1075 RPM speed rating is calibrated specifically for Lennox condenser fan blades to provide maximum heat dissipation.
• Reliable PSC Design: Utilizes a Permanent Split Capacitor for high starting torque and consistent efficiency across its operational life.
• Duty-Cycle Durability: Engineered for 460V single phase systems, providing stable performance in heavy-duty commercial environments.
• Simplified Installation: Features standard 48 frame dimensions and a 3.63-inch shaft length for a clean mechanical fit.

What is the rotation of the Lennox 25G21 motor?
This motor operates with a CCWLE (Counter-Clockwise Lead End) rotation. Always verify the rotation of your existing fan blade before installation to ensure proper airflow direction.

Is the capacitor included with this motor?
Capacitors are typically sold separately. This motor requires a 12.5 MFD / 370V run capacitor for correct operation and to prevent winding failure.

Can I use this 460V motor in a 230V system?
No, this motor is specifically wound for 460V 1PH power. Attempting to run it on lower voltage will result in insufficient torque and eventual motor burnout.
