912 210 002 0 Compatible Single Cylinder Compressor

What does a single cylinder compressor do?

This single cylinder air brake compressor serves as a critical component in the pneumatic braking system of heavy commercial vehicles. By utilizing a piston-type mechanism, it compresses intake air and directs it toward the air processing unit and storage tanks. This specific model is designed as a water-cooled unit, meaning it integrates into the engine's cooling circuit to maintain stable operating temperatures during sustained heavy-duty use.

Technical specifications and fitment

This component is engineered for reliability in demanding environments. It features a Ø100.00 bore and a 50 mm stroke, providing a swept volume of 393cm³. The unit is equipped with an M26x1,5 air outlet port and M14x1,5 water inlet/outlet ports to ensure precise integration into existing pneumatic and cooling architectures. This compressor is compatible with WABCO systems.

Installation and maintenance guidance

For professional technicians and fleet managers, regular inspection of the through drive and cooling connections is essential to prevent system pressure drops. Maintaining the integrity of the water-cooled valve plate and ensuring clean air intake will extend the service life of the internal piston assemblies. Always verify that all port connections are tightened to specification to avoid leaks in the pneumatic circuit.

Troubleshooting air pressure issues

Proper selection of this compressor ensures consistent air pressure for braking performance in heavy-duty applications. If air pressure builds too slowly or leaks are detected at the M26x1,5 outlet, a thorough system inspection is required.
