Lennox 25J43 Motor
The Lennox 25J43 Blower Motor is a high-performance OEM replacement motor designed for heavy-duty air movement in 460V HVAC systems. Engineered for durability in both light commercial and residential air handlers, this 3/4 HP motor operates at a fixed 1075 RPM to maintain consistent static pressure and optimal airflow cycles. As a specialized 460V single-phase motor, it is built to withstand the rigorous demands of industrial environments while ensuring quiet, vibration-free operation through its precision-balanced internal assembly. This Lennox 25J43 features a standard NEMA frame for seamless mechanical integration and sleeve bearings for reliable long-term service in horizontal mounting positions. Contractors typically utilize this model for direct-drive blower applications where high-voltage efficiency and thermal stability are critical for system performance. Verify the 10 MFD 370 VAC capacitor requirement and lead wire configurations to ensure a drop-in match for your specific Lennox furnace motor or air handler assembly.
Key Benefits- OEM Direct Fit: Guaranteed mechanical and electrical compatibility for select Lennox air handlers and furnaces, eliminating field modifications.
- High-Voltage Efficiency: Optimized for 460V 1PH systems, providing stable torque and reduced amperage draw during peak operation.
- Three-Speed Versatility: Features multi-speed taps (3-speed) to fine-tune CFM delivery based on specific heating or cooling requirements.
- Rugged Construction: Built with an Open Drip Proof (ODP) enclosure to facilitate maximum heat dissipation and extend operational life in controlled environments.
- Standardized Mounting: Uses a 1/2-inch diameter by 2.5-inch long shaft and standard hub ring/belly band compatibility for fast installation.
What is the required capacitor for the 25J43 motor?
This motor requires a 10 MFD 370 VAC run capacitor (sold separately) to maintain proper Phase angle and starting torque.
Can this motor be used in 208-230V applications?
No. This is a dedicated 460V 60Hz motor. Applying lower voltage will result in motor failure and potential control board damage.
What is the rotation direction for this model?
The Lennox 25J43 is rated for CCWLE (Counter Clockwise Lead End) rotation, which is the standard for most direct-drive blower wheels in this class.
