Description

The single cylinder air compressor is a critical component within the pneumatic system of heavy commercial vehicles, ensuring consistent air pressure for braking and suspension systems. This high-strength component is designed to operate under demanding thermal conditions through an efficient water-cooling mechanism.

This Vaden Original air compressor is the OE equivalent of the VOLVO 20733974 part used in the VOLVO FH12 D12C engine. It features a Ø85.00 mm cylinder bore, a 56 mm stroke, and a 318cm³ swept volume to meet precise technical requirements. The unit includes an M26x1,5 air outlet port and an M12x1,5 air unloader port for seamless integration.

For workshop technicians, installation requires careful attention to the water cooling ports (M16x1,5) and the air inlet (Ø35). Ensuring all connections are secure and following the specified maintenance intervals for the engine's pneumatic system will optimize the lifespan of the compressor and maintain vehicle safety.

Regular inspections of the through-drive and water cooling paths are recommended to prevent system failures during heavy-duty operation.
