Lennox 14F83 Compressor

The Lennox 14F83 is a high-performance 5-ton R22 compressor designed for demanding commercial and residential HVAC applications. This three-phase scroll compressor operates at 208/230V and 60Hz, delivering a nominal cooling capacity of 57,500 BTUH. As a primary HVAC replacement compressor, the 14F83 serves as the direct 1-to-1 substitute for the obsolete Lennox 15M85 and 25M84 models, ensuring a seamless fit and electrical compatibility for existing system footprints. Engineered with Copeland scroll technology (model ZR57KCE-TF5-830), this unit features a 7/8-inch suction line and a 1/2-inch discharge for standard line set brazing. With an 11.5 EER efficiency rating, it provides reliable refrigerant circulation and thermal management in large-scale air conditioning and chiller systems. The 14F83 maintains system integrity and performance levels originally specified by Lennox, making it the standard choice for contractors looking to restore full 5-ton cooling capacity without re-engineering the liquid or suction lines.
