Lennox 11C30 is a factory-approved scroll compressor manufactured by Copeland, model ZR28K5E-PFV-800. It is designed for residential and light commercial air conditioning systems that operate with R-22 refrigerant and require dependable performance, quiet operation, and long service life.

This compressor delivers a nominal cooling capacity of 28,400 BTUH and is commonly used in approximately 2.5-ton systems. The scroll design provides higher efficiency and fewer moving parts compared to reciprocating compressors, helping reduce wear, vibration, and noise during operation. With an 11 EER rating, it offers solid energy performance for legacy R-22 applications.

It operates on 208 to 230 volts, single-phase, 60 Hz power, making it suitable for standard North American electrical systems. The ZR28K5E-PFV-800 is built to OEM specifications and is intended as a direct replacement in compatible Lennox systems where original performance and fit are required.
