1100 015 020 Twin Cylinder Compressor for Mercedes-Benz

What does a twin cylinder compressor do?

This twin cylinder compressor is a critical component within the air brake system of heavy commercial vehicles, designed to generate a high volume of compressed air via two piston-cylinder assemblies. By utilizing two compression strokes per crankshaft revolution, this unit provides significantly higher air output than single-cylinder alternatives, making it ideal for high-demand applications. It is constructed with heavy-duty grade materials to ensure long-term durability in harsh operating environments.

Vehicle compatibility and fitment

This specific model is compatible with Mercedes-Benz vehicles and meets the requirements of WABCO systems. The unit features a 636cm³ swept volume and is designed as a water-cooled component to manage thermal loads effectively during continuous operation. It is an essential replacement part for maintaining optimal pneumatic pressure in heavy-duty braking circuits.

Installation and maintenance

Installation and maintenance should be performed by a workshop technician to ensure correct alignment and torque. This water-cooled unit includes a water inlet port (M14x1,5) and an outlet port (M16x1,5) to integrate seamlessly into the existing cooling circuit. Technicians should verify all connections, including the Ø30 air inlet port and M26x1,5 outlet port, to prevent pressure leaks.

Troubleshooting and selection

Regular inspection of the through drive mechanism and cooling lines is recommended to prevent system failures. Ensuring the compressor operates within its specified thermal limits helps maintain consistent air reservoir filling rates in multi-axle tractor units or heavy trucks.
