1100 290 002 Mercedes-Benz Compatible Twin Cylinder Compressor

What does a twin cylinder compressor do?

This twin cylinder compressor functions as a critical engine-driven component within the air brake system of heavy commercial vehicles. By utilizing two piston-cylinder assemblies, it generates a higher volume of compressed air compared to single-cylinder units, facilitating faster reservoir filling. This makes it an essential component for heavy-duty applications requiring consistent pneumatic pressure.

Vehicle compatibility and features

This specific unit is compatible with Mercedes-Benz vehicles and is engineered to meet strict operational standards. It features a water-cooled design to manage thermal loads effectively during continuous operation. The assembly includes an integrated ESS feature and a water-cooled valve plate to ensure long-term reliability under heavy workloads.

Technical specifications and installation

Technical specifications for this unit include a cylinder bore of Ø85.00 mm and a stroke of 56 mm, resulting in a 636cm³ swept volume. The air inlet and outlet ports are sized at M26x1,5, with an unloader port of M12x1. Installation should be performed by a workshop technician to ensure correct alignment of the through drive and secure connection of the M14x1,5 water inlet and M16x1,5 water outlet ports.

Maintenance considerations

Maintaining proper coolant flow through the water ports is vital to prevent overheating and ensure the integrity of the internal components.
