20701801 VOLVO FM 480 Twin Cylinder, Air Compressor

This twin cylinder air compressor serves as a critical component in the pneumatic system of heavy commercial vehicles, providing consistent air pressure required for braking and auxiliary functions. Designed with high-strength components, it ensures long-term durability and operational stability under heavy-duty cycles.

20701801 is the OE-equivalent of the VOLVO 20701801 twin cylinder air compressor used in the VOLVO FM 480. This part is engineered to meet strict technical standards for precise fitment and performance within the vehicle's air brake system.

The assembly features a Ø85.00 mm cylinder bore and a 62 mm stroke, optimized for a 704cm³ swept volume. The unit is water-cooled (W) via M16x1,5 inlet and outlet ports, ensuring efficient thermal management during operation. It includes an ESS feature and a water-cooled valve plate to maintain optimal performance in high-temperature environments.

Workshop technicians should ensure that the water inlet (M16x1,5) and outlet (M16x1,5) connections are properly secured to prevent leaks. The air inlet port is Ø35 and the air outlet port is M26x1,5. Regular inspections of the through-drive mechanism and cooling lines are recommended to maintain system integrity.
