2500 330 001 Air Compressor for Cummins ISB engines

This single cylinder air compressor is a vital component in the pneumatic braking system of heavy commercial vehicles, providing the necessary compressed air for brake operation. Designed with a water-cooled valve plate and through drive mechanism, it ensures optimal thermal management and efficient performance under heavy-duty operating conditions. The robust construction helps maintain consistent pressure delivery to the air processing unit.

This compressor is compatible with various heavy commercial vehicles, including International models like the 3300, Durastar, and Workstar, as well as Freightliner, Kenworth, and Peterbilt trucks equipped with Cummins ISB engines. It is also fitted to Ram (Dodge) series, Ford Trucks, Blue Bird, and Volkswagen Constellation vehicles. These units are engineered to meet the demands of diverse fleet applications.

For optimal performance, technicians should verify the installation of the water inlet and outlet ports, specifically the 3/4" - 16 UNF connections. Regular inspection of the air unloader port and intake assembly is recommended to prevent system contamination. Maintaining proper cooling flow through the water jacket is essential for extending the service life of the internal piston and ring assemblies.

Consult your authorized distributor to ensure precise fitment for your specific engine configuration.
