A9061305015SP1 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 system of heavy commercial vehicles. It functions by compressing intake air to provide the necessary pressure for the air brake system and air processing units. By utilizing a high-strength design, it ensures consistent performance under demanding operating conditions.

Vehicle and engine compatibility

This specific model is compatible with Mercedes-Benz vehicles. It is engineered with a water-cooled configuration to prevent overheating during continuous operation, featuring an Ø85.00 mm cylinder bore and a 42 mm stroke for efficient air output. The unit includes an M26x1.5 air inlet port and M14x1.5 water ports to facilitate seamless integration.

Installation and maintenance

For professional installation, technicians should verify the rotation direction and ensure all water and air connections are properly seated to prevent leaks. Maintaining clean intake air and checking the water cooling lines during routine service helps extend the service life of the piston and ring assemblies. Consult your authorized distributor for installation guidance.

Troubleshooting guidance

A malfunctioning compressor can directly impact braking performance. If air pressure build-up is slow or the system fails to maintain pressure, inspecting the water ports and valve plate is recommended to ensure optimal system interplay.
