A4571304915S Twin Cylinder 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, it ensures a higher air output compared to single-cylinder units, facilitating faster reservoir filling. This unit is engineered with high-strength components to withstand rigorous operational cycles in demanding environments.

Vehicle and engine compatibility

This specific model is designed to be compatible with Mercedes-Benz vehicles. It features a water-cooled design with a water-cooled valve plate to manage thermal loads effectively during operation. The technical configuration includes an M26x1,5 air inlet and outlet port, alongside an M12x1,5 unloader port, ensuring precise pneumatic control.

Installation and technical specifications

For workshop technicians, ensuring proper installation is vital for system integrity. This unit features a through drive configuration and an ESS feature for optimized performance. When replacing, verify that the M16x1,5 water inlet and outlet ports match the existing cooling lines to prevent leaks or thermal issues in the braking circuit.

Maintenance and troubleshooting

Maintaining stable air pressure requires regular checks of the water cooling lines and the unloader valve functionality. Regular inspection of the piston assembly helps prevent pressure drops in the pneumatic system, ensuring consistent braking performance for heavy commercial vehicle fleets.
