What does a twin cylinder compressor do?

This twin cylinder compressor is a vital component of the pneumatic braking system, responsible for generating the compressed air required for reliable braking performance. Built with high-strength components, it ensures consistent air pressure delivery even under heavy-duty operating conditions. The unit features a water-cooled design to manage thermal loads effectively during continuous operation.

Vehicle compatibility and engine fitment

This specific model is engineered for Volvo FM13 trucks equipped with D13B engines. It is designed to integrate seamlessly with the engine's drive system, maintaining optimal pressure regulation for the vehicle's pneumatic circuits. The assembly includes an ESS feature to ensure precise system control.
