85000396 VOLVO FH II 420 Twin Cylinder, Air Compressor

The high-strength component designed for the air brake system provides critical pneumatic pressure through a robust twin cylinder configuration. This air compressor is engineered to maintain consistent output under heavy-duty workloads, ensuring the stability of the vehicle's braking system. The water-cooled design facilitates efficient temperature regulation during continuous operation, which is essential for long-haul heavy commercial vehicle transport.

85000396 is the OE-equivalent Twin Cylinder, Air Compressor used in the VOLVO FH II 420. This part serves as a direct replacement for the VOLVO 85000396, ensuring seamless integration with original vehicle systems. It is specifically designed to meet the high standards required for heavy commercial vehicle engine and air-braking architectures.

For workshop technicians, this unit features a through-drive design and includes an integrated ESS feature. The installation involves connecting the water inlet and outlet ports (M16x1,5) and the air unloader port (M12x1). Proper maintenance of the water cooling circuit is vital to ensure the longevity of the valve plate and cylinders. This component is built to handle high-pressure requirements while maintaining precise volumetric efficiency.

Given its technical complexity, ensuring the correct alignment of the M26x1,5 air outlet port is necessary during assembly to prevent leaks in the pneumatic line. The 704cm³ swept volume provides the necessary air capacity for heavy-duty cycles typical in long-distance freight transport.
