Specific-Fit Heavy-Duty A/C Condenser

The Sunair CN-1028 is a condenser-only unit engineered to OE standards for reliable, like-for-like replacement in heavy-duty air-conditioning systems. Built in China, it features pad-type inlet and outlet fittings to match OE sealing surfaces and hardware. The compact 16 mm depth supports tight packaging, while the 330 mm length and 889 mm width align with the intended mounting envelope. This model is designed for R134a refrigerant and is supplied without an integrated drier, allowing technicians to select and install the appropriate receiver-drier separately.

Installation and Service Considerations

As a condenser-only component, the CN-1028 requires a separate receiver-drier to complete the refrigeration circuit. Use the correct pad gaskets and torque specifications for leak-free operation, and evacuate and recharge the system with R134a per vehicle/service guidelines. The pad-style connections provide secure sealing when properly assembled and simplify replacement in applications originally equipped with pad fittings.

Fleet Procurement and Interchange

For parts consolidation and fleet maintenance planning, this condenser cross-references common industry numbers including Four Seasons 40831, Red Dot RD473650/RD473650P, Kenworth/Peterbilt/Paccar M3659001 and R0440001, UAC CN22050PFC, and Truck Air 040715/041422. Aligning on these references helps streamline sourcing while maintaining OE-equivalent fit and function in the specified applications.
