20770303 Compressor compatible with Volvo FH13

What does a twin cylinder compressor do?

This twin cylinder compressor plays a vital role in the pneumatic braking system of heavy commercial vehicles by generating the necessary compressed air for braking and suspension operations. Built with high-strength components, it ensures consistent air delivery even under intense thermal loads through its efficient water-cooling design.

Vehicle and engine compatibility

This specific model is designed for Volvo FH13 trucks equipped with D13A engines. It provides a swept volume of 636cm³ and features an integrated ESS feature for optimized system performance. This unit is compatible with Volvo OE standards to ensure seamless integration into the existing air supply architecture.

Installation and maintenance

Installation requires attention to the water inlet and outlet ports, both measuring M16x1.5, to maintain proper thermal regulation. Technicians should verify the through-drive alignment and ensure all connections, including the M26x1.5 air outlet and M16x1.5 unloader port, are secure to prevent pressure leaks.

Operational checks

Regular inspection of the water-cooled valve plate and air inlet port (Ø35) is recommended to prevent buildup that could impact compression efficiency. Maintaining clean coolant levels is essential for the longevity of this heavy-duty component.

OE cross-reference

1300 190 008 (Twin Cylinder Compressor) is the equivalent of the Volvo OE number. This part directly replaces Volvo OE number 20770303.
