3944525 Cummins Compatible Single Cylinder Compressor

What does a single cylinder compressor do?

This single cylinder compressor serves as a critical component within the air brake system of heavy commercial vehicles, providing the necessary compressed air for braking and pneumatic functions. Designed with a robust single-piston architecture, this unit ensures consistent pressure delivery under demanding operational conditions. The integrated water-cooling system helps maintain optimal thermal stability during continuous service.

Compatibility and engine fitment

This specific model is compatible with Cummins engines and is designed to meet high-performance standards. It features a through-drive design and is equipped with an Electronic Control System (ESS) feature to enhance system efficiency. The unit utilizes a water-cooled valve plate to ensure long-lasting performance in heavy-duty environments.

Installation and maintenance guidance

Technicians should note the technical specifications during installation, including the Ø25 air inlet port and the 3/4 - 16 UNF water inlet and outlet ports. Proper torque application on the M10x1 unloader port and ensuring the M27x2 air outlet connection is secure is vital for preventing leaks. Regular inspection of the water cooling lines and the single piston assembly is recommended to maintain peak pneumatic output.

Troubleshooting and selection

To ensure optimal braking performance, always verify that the compressor's displacement and cooling requirements align with the engine specifications. Maintaining clean air intake and proper coolant flow through the 3/4 - 16 UNF ports will prevent premature wear of the internal components.
