4991799 Cummins Compatible Single Cylinder Compressor

What does a single cylinder compressor do?

This single cylinder compressor serves as a critical component in the pneumatic braking system of heavy commercial vehicles. By converting mechanical energy into pressurized air, it provides the essential airflow required for the air processing unit and subsequent brake tanks. The unit features a robust construction designed to withstand high-pressure cycles and intense thermal loads during operation.

Compatibility with Cummins engines

This specific model is designed to be compatible with Cummins engines. It functions as a direct replacement for original equipment components in heavy-duty applications, ensuring that the pneumatic pressure remains consistent for the entire braking circuit.

Technical specifications and cooling

The unit is a water-cooled design, utilizing 3/4" - 16 UNF water inlet and outlet ports to manage operating temperatures effectively. Technical specifications include a Ø85.00 mm cylinder bore, a 56 mm stroke, and an air outlet port size of M27x2. It is equipped with an ESS feature and a water-cooled valve plate to enhance durability and efficiency under continuous load.

Maintenance and inspection tips

For maintenance, technicians should regularly inspect the water cooling lines and ensure the M10x1 unloader port remains free of debris to prevent pressure fluctuations.
