21379906 Volvo FM13 D13B Twin Cylinder Compressor

What does a twin cylinder compressor do?

This twin cylinder compressor serves as a critical component within the air brake system, ensuring consistent pneumatic pressure for heavy commercial vehicle braking operations. Built with heavy-duty grade materials, it is designed to withstand high thermal loads through an integrated water-cooling system, which maintains stable performance during long-haul transport cycles.

Vehicle and engine compatibility

This specific unit is engineered for Volvo FM series trucks, including models such as the FM 390, FM 460, and FM 500. It is specifically compatible with Volvo FM13 engines equipped with the D13B configuration. The design ensures seamless integration with the vehicle's existing pneumatic architecture.

Installation and maintenance

Installation requires careful attention to the water inlet and outlet ports (M16x1.5) to prevent cooling leaks. The unit features an air unloader port (M16x1.5) and an M26x1.5 air outlet port. Technicians should verify that the through drive mechanism is correctly aligned during assembly to prevent premature wear of the internal components.

System maintenance guidance

Maintaining clean coolant and air filtration helps extend the service life of the valve plate and cylinders. For optimal performance, check all connections and pressure settings during routine fleet inspections. Consult your authorized distributor.
