A9061304715SP2 Mercedes-Benz Twin Cylinder Air Compressor

What does a twin cylinder compressor do?

This engine-driven twin cylinder compressor serves as a critical component within the air brake system of heavy commercial vehicles. By utilizing two piston-cylinder assemblies, it provides a higher air output compared to single-cylinder units, ensuring faster reservoir filling and consistent pressure for braking operations. The unit is constructed with high-strength components to withstand the rigorous thermal and mechanical demands of heavy-duty service.

Vehicle and engine compatibility

This specific model is compatible with Mercedes-Benz trucks and buses. It is engineered to integrate seamlessly into the pneumatic system of Mercedes-Benz vehicles, providing stable air supply for multi-axle tractor units or heavy coaches. The design incorporates ESS features and a water-cooled valve plate to manage operating temperatures effectively during continuous use.

Installation and maintenance

For installation, technicians should verify the water inlet port (M14x1,5) and outlet port (M16x1,5) connections. Given the 19.4 kg weight and specific displacement of 636cm³, ensuring correct mounting alignment and secure connection of the M26x1,5 outlet port is essential for preventing leaks. Regular inspection of the water cooling lines is recommended to maintain optimal performance.

Troubleshooting guidance

Checking for air leaks around the unloader port (M12x1,5) or monitoring pressure build-up rates can help identify potential system issues before they lead to failure.
