3944460 Compatible C50 Single Cylinder Compressor

What does a single cylinder compressor do?

This single cylinder air brake compressor serves as a critical component in the pneumatic system of heavy commercial vehicles. By compressing intake air and delivering it to the processing unit, it ensures the necessary air pressure for braking operations. This specific model is engineered with high-strength components to withstand intense thermal and mechanical stress during continuous operation.

Engine compatibility and fitment

This compressor is designed to be used in Cummins engines, including the 6BT5.9, 6CT8.3, ISB, QSB, and C50 series. It functions effectively within the engine's cooling circuit due to its water-cooled design, preventing overheating during heavy-duty cycles. This ensures stable pressure delivery even under high-load conditions.

Technical specifications and ports

The unit features a Ø75.00 mm cylinder bore and a 56 mm stroke, providing a swept volume of 247cm³. It includes an M27x2 air outlet port and M10x1 unloader port, alongside 3/4 16UNF water inlet and outlet ports for seamless integration into existing cooling systems.

Maintenance and installation guidance

Technicians should regularly inspect the water cooling lines and port connections to prevent leaks or pressure drops. Ensuring proper coolant flow through the inlet and outlet ports is vital for maintaining the integrity of the internal valve plate and piston assembly. Consult your authorized distributor for more information.
