3949718 Cummins 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 system of heavy commercial vehicles. By utilizing a piston-type mechanism, it compresses intake air to provide the necessary pressure for the air brake system, ensuring reliable braking performance and system stability during operation.

Compatibility and engine fitment

This specific model is engineered to be compatible with Cummins engines and is designed to withstand demanding service conditions. It features a water-cooled design to manage thermal loads effectively, maintaining consistent performance even under high-pressure requirements typical in heavy-duty environments.

Technical specifications and installation

Technical specifications include a cylinder bore of Ø85.00 mm and a stroke of 56 mm, resulting in a swept volume of 318cm³. The unit is equipped with an M27x2 air outlet port and an M10x1 air unloader port. For proper installation, ensure the water inlet and outlet ports (3/4" - 16 UNF) are correctly connected to the engine cooling circuit to prevent overheating.

Maintenance and troubleshooting

Regular inspection of the water-cooled valve plate and through drive components is recommended to maintain optimal air output. Maintaining correct lubrication and cooling flow will help prevent premature wear in the piston assembly, ensuring long-term reliability for the vehicle's pneumatic systems. Consult your authorized distributor.
