Design & Construction
The 48Y NEMA frame provides a standardized footprint for straightforward OEM replacement and retrofit installations. The stud mount configuration simplifies secure attachment to condenser fan decks and brackets. SAB bearings deliver a balanced combination of smooth, quiet operation and extended service life, making this motor well-suited for continuous-duty condenser fan service.
Performance & Reliability
Running at a low 825 RPM, the LX7931 is optimized for efficient airflow delivery across condenser coils while minimizing noise and vibration. The counterclockwise (CCW) rotation at the lead end is a critical specification to confirm compatibility with your existing fan blade pitch and condenser assembly. At 1.7 full load amps, this motor draws minimal current, contributing to overall system energy efficiency.
Application
- Residential and light commercial air conditioning condenser units
- Refrigeration condenser fan applications
- OEM replacement for compatible 48Y frame condenser motors
- Stud-mount condenser fan decks requiring CCW lead-end rotation
