21516476 VOLVO Twin Cylinder, Air Compressor

The heavy-duty twin cylinder air compressor is a critical component within the pneumatic braking system of heavy commercial vehicles. Designed to provide consistent air pressure, this unit utilizes a dual-cylinder configuration to ensure reliable operation and high-strength performance under demanding driving conditions. Its robust construction is engineered to meet the rigorous standards of modern heavy-duty transport.

21516476 is the OE-equivalent of the VOLVO Twin Cylinder, Air Compressor used in VOLVO vehicles. This high-strength component features a cylinder bore of Ø85.00 and a stroke of 56 mm, resulting in a swept volume of 636cm³. It is specifically engineered for compatibility with VOLVO systems to maintain peak pneumatic performance.

For workshop technicians, this air compressor is designed for efficient installation and long-term serviceability. The unit features a water-cooled design with specific inlet and outlet ports (M16x1,5) to manage thermal loads effectively. The inclusion of an ESS feature and a water-cooled valve plate ensures optimal stability during continuous operation in heavy commercial vehicle environments.

Regular inspection of the air inlet port (Ø35) and the unloader port (M12x1,5) is recommended during routine maintenance to ensure the system remains free of debris and operates within standard parameters.
