This twin cylinder compressor plays a critical role in the pneumatic system of heavy commercial vehicles by providing consistent air pressure for braking operations. Built with high-strength components, this unit ensures reliable air delivery even under demanding service conditions. The design focuses on durability and efficient thermal management through integrated water cooling.

Vehicle and engine compatibility

This specific model is compatible with Volvo B12 trucks equipped with D12A engines. It is engineered to meet the strict requirements of the original equipment, ensuring seamless integration within the vehicle's air brake assembly. The unit features a through drive configuration and is specifically designed for high-duty cycle environments.
