A9061301115SP1 Mercedes-Benz Compatible Single Cylinder Compressor

What does a single cylinder compressor do?

This single cylinder air brake compressor is a piston-type component that generates the compressed air required for the pneumatic braking system in heavy commercial vehicles. By utilizing a single-piston, single-cylinder housing, it ensures consistent pressure delivery to the air processing unit, which is essential for safe braking performance. This component is built with high-strength components to withstand demanding operating conditions.

Vehicle and engine compatibility

This specific model is engineered for Mercedes-Benz vehicles. It features a water-cooled design to prevent overheating during continuous operation, making it suitable for heavy-duty applications. The unit includes a water-cooled valve plate and is configured with an M26x1,5 air inlet port and an Ø30 air outlet port to ensure seamless integration into the existing pneumatic circuit.

Installation and maintenance guidance

For proper maintenance, technicians should inspect the water inlet and outlet ports (M14x1,5) for any signs of leakage or blockage. Ensuring the cooling system provides adequate flow is critical for maintaining the integrity of the internal components. When replacing this unit, verify that the through drive configuration matches the existing engine drive setup to prevent installation issues.

Troubleshooting air pressure issues

Maintaining consistent air pressure starts with a healthy compressor. If the vehicle experiences slow air pressure buildup or irregular braking response, the compressor should be inspected for internal wear or cooling inefficiencies.
