Lennox 11A95 Compressor

The Lennox 11A95 (Copeland CR32K6E-PFV-875) is a professional-grade hermetic reciprocating compressor engineered for high-temperature air conditioning and heat pump applications. Delivering a nominal 32,000 BTU (2.5 Ton) capacity, this single-phase, 208-230V unit is a critical service component for R-22 systems and is also compatible with R-407C retrofits when using POE oil. As a direct OEM replacement for Lennox 72L4301 and R39311C001, it ensures seamless mechanical integration in residential condensing units and light commercial packaged systems. This 6th-generation CR series model features an internal line break overload for motor protection and a high-torque PSC motor designed for reliable starts under pressure. The robust internal suspension system minimizes vibration, maintaining decibel levels during heavy-load cycles. Contractors should note the 3/4-inch suction and 1/2-inch discharge sweat connections, along with the standard 7.5" x 7.5" mounting footprint, ensuring compatibility with a wide range of legacy equipment.

Key Technical Benefits:

• Direct OEM Compatibility: Serves as the primary replacement for Lennox 72L43, 52M2101, and 11W94, reducing field modification time.
• Versatile Refrigerant Application: Optimized for R-22 refrigerant systems while supporting R-407C transitions.
• High Efficiency Ratings: Delivers an EER of 10.7, providing consistent cooling performance and reduced amp draw.
• Standardized Infrastructure: Uses a 35 MFD / 440V run capacitor and standard molded plug for simplified electrical hookups.
• Durable Construction: Heavy-duty steel housing and a 66-lb gross weight reflect the industrial build quality required for 24/7 HVAC operation.

Common Contractor Questions:

What oil is pre-charged in the Lennox 11A95?
The 11A95 model typically comes pre-charged with Polyolester (POE) oil, which is required for R-407C but also compatible with R-22 mineral oil systems after proper flushing.

Does this unit require a start kit?
While the PSC motor is designed for standard starting torque, a hard start kit (such as a 5-2-1) is recommended if the unit is operating in a system with non-balanced pressures or high ambient temperatures.

Is the mounting bracket included with the compressor?
The compressor includes the internal mounting grommets and sleeves, but the base rails or specific Lennox mounting frames must be retained from the original unit.
