3948846 Cummins Compatible Single Cylinder Compressor

What does a single cylinder compressor do?

This single cylinder air compressor serves as a critical component in the pneumatic braking system of heavy commercial vehicles. By utilizing a piston-driven mechanism, it compresses intake air and delivers it to the air processing unit and storage tanks. This specific model is engineered with high-strength components to withstand the rigorous thermal and pressure fluctuations inherent in heavy-duty operation.

Compatibility with Cummins systems

This compressor is designed to be compatible with Cummins systems. It is specifically built to integrate seamlessly into the engine drive setup, providing stable air pressure for braking and pneumatic auxiliary functions in heavy commercial vehicles.

Installation and maintenance guidance

For optimal performance, technicians should inspect the water cooling connections, including the 3/4 - 16 UNF inlet and outlet ports. This unit features a water-cooled valve plate and an ESS feature to maintain stable operating temperatures. Regular checks of the M27x2 air outlet and M10x1 unloader port are recommended during routine maintenance to ensure system integrity.

Troubleshooting and selection

When replacing a failing unit, verify the through drive configuration and port alignment to prevent leaks. Maintaining correct coolant flow through the water jacket is essential for preventing overheating and extending the service life of the internal piston assembly.
