1100 020 002 Mercedes-Benz Compatible Twin Cylinder Compressor

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 generates a high volume of compressed air to ensure reliable braking performance and system pressure. This unit is engineered with high-strength components to withstand the rigorous thermal and mechanical stresses found in heavy-duty environments.

Vehicle compatibility and technical specifications

This compressor is compatible with Mercedes-Benz vehicles and is designed to meet the requirements of high-air-demand applications. It features a water-cooled design with M16x1,5 inlet and outlet ports, alongside M26x1,5 air inlet and outlet ports. The unit includes an ESS feature and a water-cooled valve plate to maintain optimal operating temperatures.

Installation and maintenance guidance

For professional installation, technicians should verify the through drive configuration and ensure the M12x1,5 air unloader port is correctly positioned. Proper mounting and connection to the water cooling circuit are essential for maintaining the 636cm³ swept volume efficiency. Regular inspection of the valve plate and cooling lines prevents system pressure drops.

Troubleshooting and maintenance

Maintaining consistent air output requires checking for leaks at the M26x1,5 ports and ensuring the water cooling flow remains unobstructed. If air delivery slows or pressure builds too slowly, inspect the two cylinders for wear or valve plate integrity.
