Overview

The Sunair CO-5007CA is an S6-style air conditioning compressor engineered for mobile and industrial duty. Operating on 12 V DC, it uses a single-groove clutch with a 5.75 in (146 mm) V-belt pulley to match standard belt drives on tractors, compact equipment, and vocational vehicles. An integrated superheat switch provides thermal management, helping protect the compressor under abnormal conditions. With two spade terminals and standard wiring conventions, the unit installs cleanly as an aftermarket replacement across fleets from Agco/Allis, Bobcat, Case/IH, Caterpillar, and other major manufacturers using R134a systems.

Applications and specifications

Built on a proven S6 architecture, the CO-5007CA supports R134a refrigerant and PAG 46 lubricant to align with current service practices. The 12 V clutch coil engages positively at typical mobile system voltages, while the A1 single-groove configuration maintains belt alignment and wrap for efficient power transmission. The V-belt drive and compact pulley diameter simplify packaging in tight engine bays. For technicians, the two-terminal layout and spade connectors speed electrical hookup and troubleshooting. To ensure correct fit and performance, verify mounting head, port orientation, belt profile, and pulley diameter against the original unit before installation.
