20547525 VOLVO FH 440 Twin Cylinder, Air Compressor

The 20547525 Twin Cylinder, Air Compressor provides essential pneumatic pressure for heavy commercial vehicle braking and suspension systems. Engineered with high-strength components, this unit ensures consistent air delivery even under demanding operational cycles. Its robust construction and precision-engineered cylinders make it an ideal choice for maintaining optimal system pressure in heavy-duty trucks.

This specific air compressor is the OE-equivalent of the VOLVO 20547525 product used in the VOLVO FH 440. It features a dual-cylinder design with a swept volume of 704cm³, a cylinder bore of Ø85.00, and a stroke of 62 mm. The assembly includes a water-cooled valve plate to manage heat effectively during long-haul operations.

Workshop technicians can rely on the precise fitment of this unit, which includes an M26x1,5 air outlet port and a Ø35 air inlet port. The integration of the ESS feature and the water-cooled system ensures that the compressor operates within safe thermal limits. Regular inspection of the M16x1,5 water ports and the M12x1 unloader port is recommended to maintain peak efficiency during routine maintenance.

Designed for seamless integration into existing pneumatic circuits, this compressor maintains high performance through its specialized water-cooled architecture. The presence of the through-drive feature ensures compatibility with standard engine drive configurations found in modern heavy commercial vehicle platforms.
