2500 040 002 Compatible Single Cylinder Air Compressor

What does a single cylinder compressor do?

This single cylinder air compressor serves as a vital component within the pneumatic brake system of heavy commercial vehicles. By utilizing a piston-driven mechanism, it compresses intake air and directs it to the air processing unit and storage tanks, ensuring consistent pressure for braking performance. This unit is engineered with high-strength components to withstand rigorous duty cycles in demanding environments.

Compatibility and technical specifications

The unit is compatible with Cummins and WABCO systems, providing a reliable solution for engine-driven air production. This specific model features a water-cooled design with a 3/4”-14 NPT air inlet and outlet, alongside an M10x1 air unloader port. The through-drive configuration ensures efficient power transfer from the engine to maintain steady pneumatic output.

Installation and maintenance guidance

For maintenance and installation, technicians should verify the water inlet and outlet connections (1/2”-14 NPT) to ensure proper cooling flow. Regular inspection of the ESS feature and port integrity is recommended to prevent pressure drops in the braking circuit. Proper lubrication and cooling management are essential for preserving the longevity of the internal piston assemblies.
