21931626 VOLVO Single Cylinder, Air Compressor

This single cylinder air compressor is a critical component designed to provide consistent air pressure for heavy commercial vehicle pneumatic systems. Engineered with high-strength components, it ensures the reliable operation of the braking system under demanding service conditions. The water-cooled design helps maintain optimal operating temperatures, enhancing the overall durability of the unit.

21931626 is the OE-equivalent VOLVO single cylinder air compressor used in VOLVO heavy commercial vehicles. This component is a direct replacement for the 21931626-coded part, ensuring seamless integration into the existing air brake architecture. It is specifically engineered to meet the rigorous requirements of modern heavy-duty truck systems.

Workshop technicians should note that this unit features a Ø92.00 cylinder bore and a 54 mm stroke, providing a swept volume of 360cm³. The installation involves connecting the M26x1,5 air ports and the M16x1,5 water ports to ensure proper cooling and pneumatic flow. Regular inspections of the unloader port and water passages are recommended during routine maintenance to prevent system downtime.

Maintaining the air compressor is vital for the safety of the entire pneumatic circuit. This part is designed to fit perfectly within Volvo's heavy vehicle systems, providing stable performance throughout its service life.
