Overview
The Sunair CO-2038CAB is a Sanden-style 7H15 A/C compressor engineered for heavy-duty HVAC service. With a 12 V electromagnetic clutch and 125 mm A2 V-belt pulley, it integrates cleanly into fleets running R134a refrigerant and PAG 46 oil. The ear-mount body and single pin terminal streamline installation while delivering dependable clutch engagement under load.

Application & Fit
Built on the proven 7H15 layout, this unit aligns with ear-mount bracketry and A-profile V-belt drives common on on-highway and off-road equipment. Key specifications include a 125 mm clutch diameter (4.93 in), 12 V coil, 2-groove A-profile pulley (A2), and a 1-pin electrical terminal. Cross reference includes Sanden 4860/U4860 along with equivalents from leading aftermarket suppliers. Always verify pulley groove, clutch diameter, voltage, and mounting ear configuration against the vehicle before ordering to ensure proper belt tracking and bracket fit.

Service & Reliability
The 7H15 platform is widely supported, enabling straightforward service with standard tools and components. Using the specified R134a refrigerant and PAG 46 oil helps maintain lubrication and thermal performance across duty cycles. When correctly matched to the bracket and belt alignment, the CO-2038CAB delivers consistent cooling to reduce downtime in demanding fleet environments.
