A4721300815 Single Cylinder Air Compressor for Mercedes-Benz

What does a single cylinder compressor do?

This single cylinder air brake compressor is a vital component designed to generate the pressurized air required for the braking systems of heavy commercial vehicles. Built with high-strength components, it utilizes a piston-type mechanism to compress intake air, which is then directed to the air processing unit and storage tanks. This specific model features a water-cooled design to ensure stable performance under heavy-duty thermal loads.

Compatibility with Mercedes-Benz vehicles

This unit is specifically compatible with Mercedes-Benz vehicles. It is engineered to maintain consistent pressure delivery through its Ø92.00 mm bore and 54 mm stroke, ensuring the pneumatic system receives a steady flow of air. The integration of ESS features and a water-cooled valve plate enhances its operational efficiency in demanding environments.

Installation and maintenance guidance

For proper installation and maintenance, technicians should verify the M18x1,5 water inlet and outlet ports are correctly sealed to prevent coolant leaks. Given its 19.8 KG weight and through-drive configuration, ensure secure mounting to the engine to prevent vibration-induced wear. Regular inspection of the M26x1,5 outlet port and the M10x1 unloader port is recommended to maintain optimal system pressure.

Troubleshooting air pressure issues

If air pressure build-up slows or the compressor runs excessively long, inspect the valve plate and cooling lines for obstructions or leaks.
