A9061301815SP2 Twin Cylinder Air Compressor for Mercedes-Benz

What does a twin cylinder compressor do?

This twin cylinder compressor serves as a critical engine-driven component within the air brake system of heavy commercial vehicles. By utilizing two piston-cylinder assemblies, the unit provides high air output to ensure rapid reservoir filling and consistent pressure for braking operations. The design incorporates high-strength components to withstand the rigorous demands of heavy-duty service cycles.

Compatibility and technical specifications

This specific model is compatible with Mercedes-Benz trucks and heavy commercial applications. The assembly features a through-drive configuration, a Ø85.00 mm cylinder bore, and a 56 mm stroke. For thermal regulation, it utilizes a water cooling system with M14x1,5 inlet and M16x1,5 outlet ports, ensuring stable performance under high workloads.

Installation and maintenance guidance

When performing maintenance or replacement, technicians should verify the air unloader port (M12x1,5) and the air outlet port (M26x1,5) to ensure seamless integration with existing pneumatic lines. Proper installation of the water cooling lines is essential to prevent overheating and maintain the integrity of the water-cooled valve plate.

System performance and troubleshooting

Regular inspection of the air inlet port (Ø30) and checking for leaks in the pneumatic circuit will help maintain optimal system pressure and prevent premature component wear.
