Form, Fit, and Function

The Sunair CO-2051CA is a Sanden-style 7H15 compressor engineered for heavy-duty A/C systems operating on 12 V. It features a PV8 serpentine pulley with a 119 mm (4.69 in) clutch diameter and an ear body type for common agricultural mounting patterns. The clutch-to-mounting flange distance is 50.1 mm (1.97 in), aiding proper belt alignment in replacements. Designed for R134a refrigerant and filled with PAG 46 oil, the unit arrives ready for installation with the clutch and coil included. A single bullet terminal simplifies electrical connection.

Installation and Service Readiness

Pre-filled PAG 46 oil helps reduce install time and contamination risk during service. The PV8 pulley provides positive belt engagement under load, while the ear-mount housing supports stable attachment in vibration-prone environments. With its 7H15 profile, the compressor aligns with widely used brackets and hose configurations across agricultural fleets standardized on R134a, supporting consistent, repeatable service procedures.
