2600 120 001 Twin Cylinder Compressor Bendix Equivalent

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.

Technical specifications and performance

This high-performance component is designed for heavy-duty service, providing higher air output than single-cylinder alternatives to ensure rapid reservoir inflation. This specific model features a water-cooled design to maintain thermal stability during sustained high-demand operations. It is engineered with a 70.64mm cylinder bore and a 38mm stroke, delivering a swept volume of 336cm³. This unit includes an ESS feature and a water-cooled valve plate to ensure reliable performance under extreme conditions.

Vehicle and engine compatibility

The compressor is compatible with a wide range of heavy commercial vehicles including Freightliner (Cascadia, Century Class, Columbia), Kenworth (T600, T800, W900), and Peterbilt (379, 389). It is also fitted to Mack Titan, Western Star models, and various International engines such as the HT570. This unit is specifically designed to work with Caterpillar C15 and Detroit Diesel Series 60 engines.

Installation and maintenance guidance

For optimal service life, technicians should ensure the water inlet and outlet ports (1/2"-14 NPT) are properly sealed and the air unloader port (1/8"-27 NPT) is clear of debris. Regular inspection of the cooling circuit is essential to prevent overheating in these high-output units. Consult your authorized distributor.
