What does a twin cylinder compressor do?

This twin cylinder compressor serves as a critical component within the pneumatic braking system, ensuring consistent air pressure for heavy commercial vehicle operations. Built with high-strength components, the unit provides the necessary compression power required for demanding heavy-duty cycles and long-distance transport reliability.

Compatible vehicles and engines

This specific model is designed for Volvo FH12 trucks equipped with D12D engines. It is engineered to meet the rigorous demands of the braking system, ensuring optimal airflow and pressure stability during operation. It is also compatible with other heavy commercial vehicle applications requiring high-volume air output.

Technical specifications and installation

Technical specifications include a Ø85.00 mm cylinder bore and a 62 mm stroke, resulting in a 704cm³ swept volume. The unit features a water-cooled design with M16x1,5 water inlet and outlet ports to manage thermal loads effectively. For maintenance, ensure the M26x1,5 air outlet and M12x1,5 unloader port connections are secure and free of debris.

Maintenance and troubleshooting

Regular inspection of the water cooling lines and air ports is recommended to prevent pressure drops or overheating. Maintaining clean air intake and proper cooling flow ensures the longevity of the internal valve plate and overall compressor performance.
