1100 225 001 Twin Cylinder Air Compressor for Mercedes-Benz

What does a twin cylinder compressor do?

This twin cylinder compressor serves as a vital engine-driven component within the air brake system of heavy commercial vehicles, generating the compressed air required for braking and pneumatic operations. By utilizing two piston-cylinder assemblies, this unit provides higher air output and faster reservoir filling compared to single-cylinder alternatives. It is built with heavy-duty grade materials to ensure reliability under constant pressure cycles.

Compatible vehicles and systems

This component is specifically compatible with Mercedes-Benz vehicles. The unit features a water-cooled design with specific port dimensions including an M16x1,5 water outlet port and an M14x1,5 water inlet port. It is also compatible with WABCO systems, making it a reliable choice for fleet maintenance and heavy-duty service requirements.

Installation and maintenance

For optimal performance, technicians should verify all connection points, including the M26x1,5 air outlet port and the M12x1,5 air unloader port. Regular inspection of the cooling lines and the through drive mechanism is recommended to maintain system integrity. Ensuring clean coolant flow helps prevent overheating during intensive braking cycles.

Selection and troubleshooting

Proper selection ensures compatibility with the vehicle's pneumatic architecture and engine mounting interface. When replacing worn units, verifying the Ø85.00 mm bore and 56 mm stroke specifications is essential for maintaining correct air delivery rates across the pneumatic circuit.
