21379906 Compressor compatible with Volvo FM series

What does a twin cylinder compressor do?

This twin cylinder compressor serves as a critical component within the pneumatic braking system, providing the necessary air pressure for reliable vehicle deceleration and system operation. Built with high-strength components, it is specifically designed to withstand the thermal and mechanical stresses of heavy commercial vehicle service environments.

Vehicle and engine compatibility

This unit is engineered for Volvo FM II models, including variants such as the FM 370, FM 410, FM 450, and FM 500, as well as various other FM series trucks. It is compatible with Volvo systems that require a water-cooled configuration to maintain optimal operating temperatures during continuous use.

Installation and maintenance guidance

Installation requires careful attention to the water inlet and outlet ports (M16x1.5) to ensure proper cooling flow. Technicians should verify that the through drive and air unloader port (M16x1.5) match existing engine specifications to prevent system leaks or pressure imbalances. Regular checks of the water-cooled valve plate are recommended during routine maintenance intervals.

Selection and performance

When replacing an existing unit, ensure that the swept volume of 704cm³ and port sizes align with the original equipment to maintain correct system performance.
