3104216RX Compatible QSX15 Single Cylinder Compressor

What does a single cylinder compressor do?

This single cylinder air brake compressor is a piston-type component designed to produce the compressed air necessary for the pneumatic brake system in heavy commercial vehicles. By taking drive from the engine, it compresses intake air and delivers it to the air processing unit, serving as a critical first link in the entire air brake circuit.

Compatibility and technical configuration

This specific model is compatible with Cummins systems and features a water-cooled design to prevent overheating during heavy-duty operations. It includes an ESS feature and a water-cooled valve plate to maintain thermal stability under high pressure. The unit is built with high-strength components to ensure longevity in demanding environments.

Installation and maintenance guidance

The technical configuration includes a Ø85.00 mm cylinder bore and a 56 mm stroke, providing a swept volume of 318cm³. For installation, note the M27x2 air outlet port and M18x1.5 water inlet/outlet ports. Maintaining proper coolant flow through these ports is essential for preventing premature wear of the piston and ring assemblies.

Troubleshooting and system performance

Regular inspection of the air unloader port and water connections can help prevent pressure fluctuations or overheating issues in the braking system. Consult your authorized distributor to ensure correct fitment for your specific engine application.
