Overview

The Sunair CO-3000A is identified across aftermarket listings as a new, OE‑style replacement air conditioning compressor sold as a stand‑alone assembly under part number CO‑3000A. It is described as a direct replacement intended to match original equipment form and function in compatible vehicle and equipment A/C systems. The compressor follows York‑style architecture with ER210R compressor type and a Roto‑Lock body, aligning with common heavy‑duty service practices. Available data specifies R134a refrigerant compatibility with PAG 46 oil. While displacement and detailed mounting dimensions are not published in the available sources, the consistent OE‑type positioning indicates that, when correctly applied, the CO‑3000A is designed to integrate with existing brackets, hoses, and system controls.

Fit & Service Notes

The RH‑hand configuration and Roto‑Lock ports support standard Rotolock fittings to streamline hose connections and maintain sealing integrity. Supplied as a new replacement unit built to match OE standards, the CO‑3000A is intended to function like the original compressor it replaces, helping restore cabin cooling performance during service or overhaul. Verify system refrigerant, oil type, port orientation, and head style prior to purchase. During installation, evacuate and flush the system as required, replace the receiver‑drier and the expansion/orifice device, and adjust total oil charge to the vehicle or equipment manufacturer’s specification for reliable operation.
