2500 040 005 Compatible Single Cylinder Compressor

What does a single cylinder compressor do?

This single cylinder air compressor functions as a critical component in the pneumatic system of heavy commercial vehicles. It operates by compressing intake air and delivering it to the air processing unit to ensure the brake system maintains required pressure levels. Built with high-strength components, this water-cooled unit is designed to handle intense thermal loads during continuous operation.

Compatibility and application

The unit is designed to be compatible with Cummins and WABCO systems. It is particularly suited for applications requiring a compact, reliable air source for heavy-duty braking cycles. This component ensures steady pressure delivery to the air tanks, which is vital for the safety and performance of the vehicle's pneumatic system.

Installation and maintenance

Installation and maintenance should focus on ensuring the water inlet and outlet ports (1/2”-14 NPT) are free from debris to maintain efficient cooling. Technicians should regularly inspect the 3/4”-14 NPT air ports and the unloader port for any signs of leakage or buildup to prevent system pressure drops.

System reliability

Monitoring the compressor's performance helps prevent brake failure in heavy commercial vehicles. Regular checks of the cooling lines and drive connections are recommended to maintain optimal service life.

OE cross-reference

2500 040 005 (Single Cylinder Compressor) is the equivalent of the Cummins and WABCO OE numbers. This part directly replaces Cummins OE number 3357113. It also replaces WABCO OE number 9111555110.
