What does a twin cylinder compressor do?

This twin cylinder compressor serves as a critical component within the pneumatic braking system, providing the necessary air pressure for heavy commercial vehicle operations. Built with high-strength components, it ensures consistent performance under demanding thermal conditions through its integrated water-cooling system.

Vehicle and engine compatibility

Designed specifically for Volvo FM12 trucks, this unit is compatible with various configurations including the FM 12/340, FM 12/380, and FM 12/460 models equipped with D12D engines. It is also fitted to Volvo FM 12H series variants to ensure precise pneumatic system support.
