The Lennox 34W52 is a genuine OEM ZR47K3-TF5-835 scroll compressor rated at 47,500 BTUH (approximately 4 tons) for 208/230V, three-phase, R-22 systems. Built for larger residential and light-commercial applications, this compressor pressurizes and circulates refrigerant to carry heat away from the conditioned space. Its three-phase scroll design delivers robust, efficient operation as a direct factory replacement for compatible Lennox units.

Common failure symptoms: A failing compressor typically causes loss of cooling, warm supply air, breaker trips, unusual grinding or rattling noises, high head pressure, or a unit that draws power but won't start. On three-phase equipment, phase imbalance or contactor issues can also accelerate compressor failure.

Why OEM matters: The genuine Lennox 34W52 matches the exact displacement, three-phase electrical characteristics, and mounting geometry your system was designed for. Installing a factory-specified OEM compressor protects the rated capacity and efficiency of your equipment, ensures compatibility with your controls, and helps preserve manufacturer warranty coverage.
