21353433 Single Cylinder, Air Compressor — VOLVO

This single cylinder air compressor is engineered to provide reliable air pressure for heavy commercial vehicle pneumatic systems. Designed for high-demand environments, it serves as a critical component in maintaining the operational integrity of the vehicle's braking and pneumatic-driven functions.

21353433 is the OE-equivalent Single Cylinder, Air Compressor used in VOLVO systems. This component is engineered to meet strict technical standards, ensuring seamless integration with the original engine and pneumatic architecture. It is specifically designed for heavy-duty applications where consistent air delivery is essential.

The installation process requires precise alignment with the through-drive mechanism. The unit features a water-cooled design with specialized inlet and outlet ports (M16x1,5) to manage thermal loads effectively during operation. Workshop technicians should ensure all port connections—including the M26x1,5 air outlet and M12x1,5 unloader port—are secured to prevent pressure loss or leaks.

Maintaining proper cooling through the water-cooled valve plate and ensuring the ESS feature functions correctly will extend the service life of the compressor. Regular inspection of the cylinder bore and stroke performance is recommended during routine heavy vehicle maintenance cycles to ensure optimal system pressure.
