What does a twin cylinder compressor do?

This twin cylinder compressor plays a critical role in the pneumatic braking system of heavy commercial vehicles, providing the necessary compressed air for reliable braking performance. Engineered with high-strength components, this unit features a water-cooled design to manage thermal loads effectively during continuous operation in demanding environments.

Compatible vehicles and engines

This specific model is designed for Volvo FH12 trucks equipped with D12C engines. It maintains high efficiency through its 704cm³ swept volume and through-drive capability, making it a reliable replacement for original equipment in the Volvo series.
