Overview: The Sunair CO-2346CA is a 24V, Sanden-style 7H15 compressor built for heavy-duty air conditioning performance. Featuring a direct-mount body and R134a compatibility, it provides dependable cooling for vocational trucks, buses, and off-highway equipment. The unit aligns with VMRS 001-001-002 for A/C and heating components, supporting fleet standardization and simplified part identification.

Specifications & Fit: This compressor uses a PV8 (8‑rib) serpentine drive with a 132 mm (5.2 in) clutch diameter for stable belt engagement and reliable cycling under load. Electrical hookup is streamlined via 2 pin-type terminals, and the 24V clutch coil integrates with common heavy-duty electrical architectures. The 7H15 architecture is widely supported, aiding serviceability and component availability. Use with R134a refrigerant and PAG 46 oil per system requirements. Typical cross-references include Sanden 6034/8242 and UAC CO8242C, among others, to help confirm application.

Installation & Service Notes: The direct-mount configuration minimizes bracket complexity and helps reduce install time in compatible systems. Verify pulley alignment, coil voltage (24 V), and terminal orientation prior to commissioning. Charge only with R134a and the specified PAG 46 oil to maintain compressor durability. For 12V systems, a comparable variant (CO-2364CA) with similar mechanical specifications is available.
