21516476 VOLVO Twin Cylinder, Air Compressor

This heavy-duty Twin Cylinder, Air Compressor serves as a critical component within the pneumatic system of heavy commercial vehicles, ensuring consistent air pressure delivery. Designed with a focus on durability, the unit utilizes high-strength components to maintain reliable performance under intense operating conditions. The integration of a water-cooled system ensures optimal thermal management during continuous operation.

21516476 is the OE-equivalent of the VOLVO 21516476 air compressor used in VOLVO heavy-duty vehicles. This precision-engineered part is specifically developed to meet strict technical requirements for compatibility and performance. The unit features a cylinder bore of Ø85.00 and a 56 mm stroke, providing a swept volume of 636cm³ for efficient air compression.

Workshop technicians can rely on the precise fitment of this assembly, which includes an M26x1,5 air outlet port and an M12x1,5 air unloader port. The water-cooled design requires careful attention to the M16x1,5 inlet and outlet ports during installation to ensure proper cooling flow. Regular maintenance and checking the water-cooled valve plate functionality are recommended to extend the service life of the compressor within the vehicle's pneumatic circuit.
