3558163 Cummins M11 Compressor Equivalent

What does a single cylinder compressor do?

This single cylinder air brake compressor serves as a vital component in the pneumatic braking system of heavy commercial vehicles. It functions by compressing intake air to provide the necessary pressure for the air processing unit and subsequent air tanks. Designed with high-strength components, it ensures consistent performance under demanding thermal conditions through its integrated water-cooling system.

Engine compatibility and fitment

This specific model is compatible with Cummins engines, including the M11, N14, ISM, and QSM11 series. It is designed to integrate seamlessly into the engine's drive system to maintain stable pneumatic pressure across various heavy-duty operating cycles.

Installation and maintenance guidance

For technical installation, this unit features an air outlet port of M27x2 and an air unloader port of M10x1. The water-cooled design utilizes 3/4" - 16 UNF inlet and outlet ports to manage thermal loads effectively. Maintenance technicians should regularly inspect the water ports and the ESS feature functionality to ensure optimal system integrity.

Troubleshooting and inspection

Regular monitoring of the compressed air output and checking for leaks at the Ø25 air inlet port can prevent sudden brake performance degradation. Consult your authorized distributor for detailed fitment verification.
