20547525 VOLVO FM 480 Twin Cylinder, Air Compressor

This high-strength component serves as a critical element within the pneumatic system of heavy commercial vehicles. As a twin cylinder air compressor, it is engineered to provide consistent air pressure through a robust design that integrates seamlessly with the vehicle's engine and braking systems. The unit features a water-cooled valve plate and a specialized design to ensure durability under demanding operating conditions.

20547525 is the OE-equivalent of the VOLVO 20547525 Twin Cylinder, Air Compressor used in the VOLVO FM 480. This part is engineered to meet strict technical standards for fitment and performance. The assembly includes a Ø85.00mm cylinder bore and a 62 mm stroke, ensuring the necessary swept volume of 704cm³ for efficient operation within the vehicle's air brake system.

Workshop technicians should note that this unit is water-cooled (W) and includes an ESS feature for enhanced system stability. The installation requires attention to the M16x1,5 water inlet and outlet ports to ensure proper thermal regulation. Maintaining the correct air inlet port (Ø35) and outlet port (M26x1,5) connections is essential for preventing pressure drops during heavy-duty cycles in the field.

This component is designed for precision assembly in professional workshops catering to heavy duty trucks and tractor units. By adhering to the specific dimensions of the air unloader port (M12x1) and through-drive requirements, technicians can ensure long-term reliability and prevent common pneumatic system failures.
