20382345 Twin Cylinder Compressor for Volvo VNL

What does a twin cylinder compressor do?

This twin cylinder compressor serves as a critical component in the pneumatic braking system, providing the necessary air pressure for heavy commercial vehicle operations. Engineered with high-strength components, it ensures stable air delivery under demanding duty cycles. The unit features a water-cooled design to manage thermal loads effectively during continuous operation.

Vehicle and engine compatibility

This component is specifically fitted to Volvo VNL trucks equipped with D12 engines. It operates as an OE-equivalent solution to maintain original system performance. The architecture includes an integrated ESS feature and a water-cooled valve plate to optimize pneumatic efficiency and longevity.

Installation and maintenance

When installing this compressor, technicians should verify the M26x1,5 outlet port and M16x1,5 water inlet/outlet ports are correctly sealed. Ensuring the through-drive alignment is precise will prevent premature wear on the drive mechanism. Regular inspection of the air inlet port and unloader ports is recommended to maintain optimal airflow.

Troubleshooting and selection

If air pressure drops or the unloader fails to cycle, check the integration between the compressor and the braking system valves. Using high-quality components helps prevent leaks in the pneumatic circuit and ensures reliable braking response for fleet managers.

OE cross-reference

1300 180 001 (Twin Cylinder Compressor) is the equivalent of the Volvo OE number. This part directly replaces Volvo OE number 20382345.
