2600 120 002 Air Compressor for Bendix

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 maintain thermal stability and includes an ESS feature for enhanced system reliability. With a swept volume of 336cm³ and a 38mm stroke, it provides the high air output necessary for demanding braking operations.

Vehicle and engine compatibility

This compressor is compatible with Bendix systems and is fitted to various heavy commercial vehicles, including International models such as the 9200, 9400, and various 4xxx/7xxx series. It is also used in Freightliner, Kenworth, Peterbilt, Sterling, and Western Star vehicles equipped with Detroit Diesel Series 60 engines. This unit ensures consistent performance across diverse heavy-duty applications.

Installation and maintenance

For optimal service life, technicians should ensure the water inlet and outlet ports (1/2 "-14 NPT) are properly connected to the engine coolant circuit. Regular inspection of the air unloader port (1/8 "27 NPT) and the water-cooled valve plate is recommended during routine maintenance to prevent pressure drops or overheating.

Troubleshooting and service

Maintaining the integrity of the cooling system and checking for leaks in the pneumatic lines will help prevent premature wear of the internal components.
