Description
What does a single cylinder air compressor do?
A single cylinder air brake compressor is a piston-type component that produces the compressed air required for the pneumatic brake systems in heavy commercial vehicles. This specific unit features a water-cooled design to prevent overheating during continuous operation, ensuring reliable pressure delivery for braking and auxiliary pneumatic functions.Compatible vehicles and engines
This compressor is designed for wide-ranging fitment across heavy-duty applications. It is compatible with International models such as the Durastar and Workstar, as well as Freightliner, Kenworth, and Peterbilt trucks. It also serves various engine configurations including Cummins ISB, ISL9, and ISX series. The unit is also fitted to Volkswagen and Ford Trucks models.Installation and maintenance
For optimal performance, ensure the water inlet and outlet ports (3/4" - 16 UNF) are free of debris during installation. This component is engineered with high-strength components to withstand heavy-duty service conditions. The assembly includes a water-cooled valve plate and an ESS feature to maintain system stability under varying thermal loads.Troubleshooting and selection
Regular inspection of the air inlet port (Ø25) and outlet port (M27x2) is recommended to prevent leaks or pressure drops. Consult your authorized distributor for exact application verification.OE cross-reference
