What does a twin cylinder compressor do?

This twin cylinder compressor serves as a vital component in the pneumatic braking system of heavy commercial vehicles. It is engineered to provide consistent compressed air pressure required for reliable brake operation and system stability. Built with high-strength components, this unit is designed to withstand the rigorous thermal and mechanical stresses found in heavy-duty engine environments.

Vehicle and engine compatibility

The unit is compatible with Volvo FM13 trucks featuring the D13A engine. This specific configuration is designed for seamless integration into the existing air system, ensuring optimal pressure delivery. It is also suitable for other heavy commercial vehicles requiring similar specifications.

Installation and maintenance

Technicians should verify that the water inlet and outlet ports (M16x1,5) and the air outlet port (M26x1,5) match the existing installation. This water-cooled model includes a water-cooled valve plate and ESS feature to maintain thermal stability during operation. Ensure all mounting flanges and drive gear configurations are identical to the original equipment during installation.

Troubleshooting and selection

When replacing the unit, always check that the swept volume of 704cm³ and the cylinder bore of Ø85.00 mm align with the vehicle's original requirements to prevent system imbalances.
