20547525 VOLVO FH 12/420 Twin Cylinder, Air Compressor

This twin cylinder air compressor is an essential component for the pneumatic systems of heavy commercial vehicles, ensuring consistent air pressure delivery. Designed with high-strength components, the unit features a precise Ø85.00 cylinder bore and a 62 mm stroke to manage high-pressure demands efficiently. The water-cooled design and specialized valve plate architecture provide superior thermal regulation during intense operation.

20547525 is the OE-equivalent of the VOLVO 20547525 twin cylinder air compressor used in the VOLVO FH 12/420. This part is engineered to meet strict mechanical standards for seamless integration into the vehicle's braking and pneumatic systems. By maintaining precise tolerances in the air inlet (Ø35) and outlet (M26x1,5) ports, it ensures optimal system-wide performance.

For workshop technicians, this unit offers a reliable replacement solution that facilitates easy assembly due to its through-drive design and standardized port sizes. Maintenance professionals should ensure that the water cooling connections (M16x1,5) and the unloader port (M12x1) are properly inspected during installation to prevent overheating or pressure loss. Regular checks of the ESS feature functionality are recommended to maintain peak pneumatic efficiency in the fleet.

This component is specifically developed for heavy-duty applications where reliability is non-negotiable. The integration of a water-cooled valve plate helps mitigate heat buildup, extending the service life of the internal moving parts under heavy commercial vehicle workloads.
