20478166 VOLVO Single Cylinder, Air Compressor

The heavy-duty Single Cylinder, Air Compressor is a critical component within the pneumatic systems of heavy commercial vehicles. Designed to provide consistent air pressure, this unit utilizes a single-cylinder architecture with a 352cm³ swept volume to ensure steady operation. The integration of a water-cooled system ensures thermal stability during high-load cycles, maintaining efficiency and preventing overheating in rigorous workshop environments.

20478166 is the OE equivalent of the VOLVO 20478166 single cylinder air compressor used in VOLVO heavy commercial vehicles. This component meets strict technical standards, featuring a Ø85.00 mm cylinder bore and a 62 mm stroke. The assembly is engineered for precise fitment within the engine's auxiliary systems, ensuring seamless integration with existing pneumatic architectures.

For workshop technicians and fleet managers, maintaining the air supply system is vital for vehicle safety and uptime. This compressor features an M26x1,5 air outlet port and an M12x1,5 unloader port to facilitate standard assembly procedures. Regular inspection of the water inlet and outlet ports (M16x1,5) is recommended to ensure the cooling-based thermal management functions correctly during long-distance hauling operations.
