What is a twin cylinder compressor?

A Twin Cylinder Compressor is an engine-driven unit in the air brake system of heavy commercial vehicles that generates compressed air using two piston-cylinder assemblies. This specific model features a water-cooled design to ensure stable performance under high-load conditions, preventing overheating during continuous operation.

Vehicle and engine compatibility

This unit is compatible with Foton, Freightliner, Kenworth, Peterbilt, Ford Trucks, and various bus chassis such as Blue Bird and Thomas Built Buses. It is also fitted to Iveco and Volkswagen models. The compressor is designed to meet the rigorous demands of multi-axle tractor units and heavy commercial vehicles using ISB, ISC, or ISF engines.
