A4721300515 Mercedes-Benz Compatible Single Cylinder Compressor

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 for the air processing unit and subsequent air tanks. This unit is designed with high-strength components to withstand continuous operation under demanding thermal conditions.

Compatibility and technical specifications

This specific model is compatible with Mercedes-Benz vehicles. It features a Ø92.00 cylinder bore and a 54 mm stroke, providing a swept volume of 360cm³. The design includes an integrated ESS feature and a water-cooled valve plate to maintain optimal operating temperatures during heavy-duty service.

Installation and maintenance guidance

For professional installation, ensure the water inlet and outlet ports (M18x1,5) are properly connected to the vehicle cooling circuit to prevent overheating. The air outlet port utilizes an M26x1,5 specification. Regular inspection of the water-cooled system and air unloader port (M10x1) is recommended to maintain peak pneumatic performance.

Troubleshooting and performance

Maintaining consistent air pressure is vital for braking safety. If pressure buildup slows or leaks occur at the ports, a thorough inspection of the compressor assembly is advised to ensure system integrity.
