20382346 SP1 Single Cylinder Compressor for Volvo FM12

What does an air compressor do?

This single cylinder air brake compressor serves as a vital component within the pneumatic braking system of heavy commercial vehicles, ensuring consistent air pressure delivery. Built with high-strength components, this unit is engineered to withstand rigorous operating conditions while maintaining efficient air production for the braking and suspension systems.

Vehicle and engine compatibility

Specifically designed for Volvo FM12 trucks equipped with D12C engines, this compressor ensures precise integration with the vehicle's existing pneumatic architecture. The unit features a water-cooled configuration with a Ø85.00 mm cylinder bore and a 62 mm stroke, providing the necessary swept volume for stable performance. It is also compatible with Volvo systems.

Installation and maintenance guidance

For professional installation, technicians should verify the water inlet and outlet port connections (M16x1,5) and the air outlet port (M26x1,5). Ensuring the through-drive mechanism and ESS feature are correctly aligned during installation prevents premature wear of the internal valve plate. Always check the mounting flange and rotation direction against the existing unit before replacement.

System troubleshooting and selection

Regular inspection of the water cooling lines and air inlet ports is recommended to prevent system contamination or overheating. Maintaining clean connections helps ensure the longevity of this high-performance component in demanding transport environments.
