3944525 Cummins Compatible Single Cylinder Compressor

What does a single cylinder compressor do?

This single cylinder air brake compressor serves as a critical component in the pneumatic braking system, providing the necessary compressed air for heavy commercial vehicle operation. Designed with a robust single-piston structure, it ensures consistent pressure delivery to the air processing unit and tanks. The water-cooled design helps maintain stable operating temperatures during sustained heavy-duty cycles.

Compatibility and application

This component is engineered to work with Cummins engines and is suitable for various heavy commercial vehicle applications including trucks and construction machinery. It features a through-drive configuration and integrated ESS functionality to ensure seamless integration within the engine's mechanical layout.

Installation and maintenance

Installation requires careful attention to the water cooling circuit, utilizing the 3/4" - 16 UNF inlet and outlet ports. Technicians should verify that the M27x2 air outlet and M10x1 unloader port connections are secure to prevent pressure leaks. Regular inspection of the water-cooled valve plate is recommended to maintain optimal volumetric efficiency.

Troubleshooting and selection

Maintaining proper lubrication and checking for any signs of coolant leakage around the ports will help prevent premature wear of the internal components. Consult your authorized distributor for further technical guidance.
