21521357 Compatible Twin Cylinder Compressor for Volvo FH13

What does a twin cylinder compressor do?

This twin cylinder compressor serves as a critical component in the pneumatic braking system, ensuring consistent air pressure generation for heavy commercial vehicles. Built with high-strength components, it is engineered to withstand the rigorous thermal and mechanical stresses found in heavy-duty engine environments.

Compatibility with Volvo FH13 engines

This specific unit is designed for use in Volvo FH13 trucks equipped with D13A engines. It features a Ø85.00mm cylinder bore and a 56 mm stroke to provide the necessary air volume for reliable brake system operation. It is compatible with Volvo OEM requirements and maintains high performance under heavy-duty service conditions.

Installation and maintenance guidance

For proper installation, technicians should verify the water inlet and outlet ports, which feature M16x1,5 threading. Ensure that the M26x1,5 air outlet port is correctly aligned and that the unloader port (M12x1,5) is free of debris during assembly to prevent system leaks or pressure fluctuations.

System performance and maintenance

Regular inspection of the water cooling lines and air ports is recommended to maintain optimal compressor efficiency and prevent overheating during long-haul operations.
