21225199 VOLVO Twin Cylinder, Air Compressor

The heavy-duty Twin Cylinder, Air Compressor is a critical component designed to maintain consistent air pressure within the pneumatic braking system. This high-strength component is engineered to withstand demanding operating conditions, ensuring reliable air delivery for heavy commercial vehicle systems. Its robust construction and precise dimensions are tailored for long-term durability in professional workshop environments.

21225199 is the OE-equivalent of the VOLVO 21225199 Twin Cylinder, Air Compressor used in VOLVO heavy-duty vehicles. This part features a cylinder bore of Ø85.00 and a 56 mm stroke, delivering a swept volume of 704cm³. It is specifically designed to be compatible with the structural requirements of high-performance Volvo engine and braking-related pneumatic systems.

For workshop technicians, this compressor offers ease of assembly with standardized port sizes such as the M26x1,5 air outlet and M16x1,5 water ports. The inclusion of a water-cooled valve plate and ESS feature ensures optimal thermal management during operation. Maintenance teams should verify the compatibility of the M12x1,5 air unloader port and the Ø35 air inlet port during installation to ensure seamless integration with existing heavy vehicle hardware.

This assembly is optimized for water-cooled systems to prevent overheating in high-load scenarios. The two-cylinder configuration provides steady pressure output essential for maintaining braking efficiency and system responsiveness in heavy trucks.
