Genuine OEM Lennox 29K58 scroll compressor (model ZR11M3-TWD-961) is the primary pump for your Lennox system, rated at 108,000 BTUH on 460V R-22 3-phase power. It compresses low-pressure refrigerant vapor into a high-pressure, high-temperature gas so heat can be rejected at the condenser. The orbiting-scroll design provides smooth, energy-efficient compression and reliable service in demanding commercial applications.

Signs of a failing compressor include the unit running continuously without cooling, breaker trips at startup, unusual noise or vibration, higher-than-normal amp draw, and repeated lockouts on the internal overload. Because this is an R-22 unit, worn compressors also tend to develop acid and oil breakdown that accelerates failure.

The OEM Lennox 29K58 is factory-specified for the exact voltage, capacity, and R-22 refrigerant charge of your equipment. Using the genuine part guarantees correct displacement, proper oil type and volume, and a matching terminal and mounting configuration — protecting efficiency and preserving your Lennox warranty. Install with confidence knowing it drops in and performs to factory ratings.
