1100 170 004 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 in the pneumatic braking system of heavy commercial vehicles. By utilizing a piston-type mechanism, it compresses intake air to provide the necessary pressure required for the air tanks and processing units. This specific model is an air-cooled unit, designed for efficient operation within the vehicle's engine bay environment.

Compatibility and technical specifications

This component is specifically engineered for compatibility with Mercedes-Benz vehicles. It features a cylinder bore of Ø88.00 mm and a stroke of 37 mm, delivering a swept volume of 225cm³. The design includes M26x1,5 thread sizes for both the air inlet and outlet ports, ensuring a secure fitment within the pneumatic circuit.

Installation and maintenance guidance

Maintenance technicians should regularly inspect the air inlet and outlet ports for debris to ensure optimal airflow. Given its air-cooled design, ensuring that the surrounding area remains free of excessive dust and oil buildup is vital for preventing overheating and maintaining long-term efficiency during heavy-duty operation.

System reliability and troubleshooting

The reliability of the braking system depends heavily on the consistent air output provided by this compressor. When replacing this unit, verify that all connection points match the M26x1,5 specifications to prevent pressure leaks in the braking line.
