20429339 Volvo FH12 Twin Cylinder Compressor

What does a twin cylinder compressor do?

This twin cylinder compressor serves as a critical component within the pneumatic air brake system, providing the necessary air pressure required for reliable braking performance. Built with high-strength components, it is engineered to withstand the rigorous thermal and mechanical stresses typical of heavy commercial vehicle operations.

Compatibility with Volvo FH12 models

This specific unit is compatible with Volvo FH12 models, including the FH 12/500, FH 12/340, FH 12/420, FH 12/380, and FH 12/460 variants. It is designed to meet the technical requirements of these heavy-duty engines, ensuring seamless integration into the existing air supply architecture.

Installation and maintenance guidance

Technicians should note that this is a water-cooled model featuring a water-cooled valve plate and an ESS feature for optimized performance. Installation requires attention to the M26x1,5 air outlet port and the M16x1,5 water inlet/outlet ports to prevent leaks and ensure proper thermal regulation.

System maintenance and troubleshooting

Regular inspection of the through-drive mechanism and air unloader port (M22x1,5) is recommended during routine maintenance to prevent system failures. Maintaining clean coolant flow through the M16x1,5 ports is essential for long-term durability.
