21353457 Single Cylinder, Air Compressor — VOLVO

The technical role of this single cylinder air compressor is to provide consistent and reliable pneumatic pressure for heavy-duty braking systems. Designed for high-demand environments, this component ensures the stability of the air brake system by maintaining optimal pressure levels through a robust single-cylinder mechanism.

21353457 is the OE equivalent of the VOLVO Single Cylinder, Air Compressor used in VOLVO heavy commercial vehicle systems. This part features a cylinder bore of Ø85.00 and a stroke of 62 mm, providing a swept volume of 352cm³. It is engineered to meet strict industrial standards for compatibility and long-term service reliability.

For workshop technicians and fleet managers, this unit is designed for straightforward installation within the engine's cooling and pneumatic circuits. The component includes a water-cooled design with specific inlet and outlet ports (M16x1,5) to ensure thermal stability. Regular inspections of the air unloader port and the through-drive connection are recommended during routine maintenance to ensure optimal performance.

This heavy-duty grade component is built to withstand high-pressure cycles and thermal fluctuations. Its water-cooled valve plate architecture provides an additional layer of durability for continuous operation in demanding transport environments.
