Overview

The Sunair CO-2393CA is a Sanden-style 7H15 compressor built for heavy-duty A/C and heating systems. Configured for R134a refrigerant and PAG 46 oil, it uses a 12 V coil with 2-pin terminals for straightforward electrical integration. A direct-mount body and PV6 clutch with a 6-groove pulley align to modern serpentine drives, while the clutch diameter measures 119 mm (4.69 in) for OE-style belt engagement. Classified under VMRS 001-001-002, it meets fleet procurement standards for A/C components.

Application & Fitment

Designed for LT platforms equipped with Cummins ISX 17+ engines, the CO-2393CA supports OEM-replacement service with the familiar 7H15 layout. The 4577 cylinder head maintains OE port orientation to facilitate hose routing and sealing. Direct-mount hardware minimizes bracket complexity and helps reduce install time. The 12 V magnetic clutch and 2-pin connector simplify hookup in standard heavy-duty electrical systems, making this unit well-suited for in-chassis replacement work.

Performance & Serviceability

The PV6, 6-groove pulley delivers stable belt tracking in high-duty cycles, supporting consistent cabin comfort for driver productivity and safety. R134a/PAG 46 compatibility aligns with common shop practices, aiding faster turnaround and fewer service variables. Delivered as a new assembly, this compressor is specified to restore cooling and defrost performance in demanding fleet environments while maintaining interchangeability with OEM-style components.
