21353433 Compatible Volvo FH II Compressor

What does a single cylinder compressor do?

This single cylinder compressor plays a critical role in the pneumatic braking system of heavy commercial vehicles by providing the necessary air pressure for braking and suspension functions. Built with heavy-duty grade materials, this unit is specifically engineered to withstand high-pressure operating conditions while maintaining consistent output through its robust internal assembly.

Compatible Volvo FH models

This component is compatible with Volvo FH models, including the 400, 420, 440, 460, 480, 500, 520, and 540 variants, as well as Volvo FH II versions. It is designed to integrate seamlessly into the engine's cooling circuit via the M16x1.5 water inlet and outlet ports.

Installation and maintenance guidance

For optimal performance, technicians should verify the M26x1,5 air outlet port connections and the M12x1,5 unloader port during installation. The through-drive design and water-cooled valve plate ensure thermal stability during long-haul operations. Regular inspection of the air inlet port and cooling lines is recommended to prevent system contamination.

System integration and troubleshooting

When replacing this unit, ensure the ESS feature and water cooling connections are properly aligned with the vehicle's existing pneumatic architecture to maintain system integrity.
