21379906 VOLVO Twin Cylinder, Air Compressor

This high-strength component is designed to provide reliable air compression for heavy commercial vehicle braking and pneumatic systems. As a twin-cylinder unit, it ensures consistent pressure generation through its optimized 704cm³ swept volume and robust mechanical structure. The integrated water-cooling system and water-cooled valve plate are engineered to manage thermal loads effectively during intensive operation.

21379906 is the OE-equivalent of the VOLVO 21379906 Twin Cylinder, Air Compressor used in VOLVO heavy commercial vehicles. This part is specifically designed to meet the rigorous demands of the vehicle's air brake system, maintaining optimal performance under high-pressure conditions. The assembly features an Ø85.00 cylinder bore and a 62 mm stroke to ensure precise volumetric efficiency.

For workshop technicians, this unit offers seamless integration with existing cooling lines via the M16x1,5 water inlet and outlet ports. The inclusion of an ESS feature and a through-drive design provides high durability and ease of installation. Regular maintenance of the cooling system and checking the M26x1,5 air outlet connections are recommended to ensure long-term serviceability in heavy-duty environments.
