003 131 50 01 Single Cylinder Air Compressor for Mercedes-Benz

What does a single cylinder compressor do?

This single cylinder air brake compressor serves as a critical component within the pneumatic braking system of heavy commercial vehicles. By converting mechanical energy into compressed air, it provides the necessary pressure required for effective braking performance and system stability. This specific unit is built with high-strength components to withstand the rigorous duty cycles found in professional transport environments.

Vehicle and engine compatibility

Designed to be compatible with Mercedes-Benz vehicles, this air-cooled unit features a 75mm cylinder bore and a 36mm stroke, delivering a swept volume of 159cm³. It is also fitted to other Mercedes-Benz trucks and buses. The design ensures efficient air delivery through its M26x1.5 air inlet and outlet ports, maintaining consistent pressure for the air processing unit.

Installation and maintenance

For workshop technicians, maintaining correct clearance and checking the air inlet/outlet ports is essential for optimal performance. This air-cooled model is engineered for simplified installation and reliable operation without the need for an external water cooling loop. Always verify the port sizes and mounting configuration during replacement to ensure seamless integration.

Troubleshooting guidance

Regular inspection of the piston and ring assembly can help prevent pressure drops in the braking circuit. If you notice a decrease in air tank pressure or increased engine load during compression, it may be time to inspect this component. Consult your authorized distributor.
