21379906 SP2 Compatible Twin Cylinder Compressor

What does a twin cylinder compressor do?

This twin cylinder compressor serves as a critical component within the pneumatic braking system, providing the necessary compressed air for heavy commercial vehicle operations. Built with high-strength components, it is engineered to maintain consistent pressure under demanding service conditions typical for long-haul transport.

Compatibility with Volvo VNL engines

This specific unit is designed for use in Volvo VNL trucks equipped with D13 engines. It features a water-cooled design to manage operating temperatures effectively, a Ø85.00 mm cylinder bore, and a 62 mm stroke. The assembly includes an M26x1.5 air outlet port and an M16x1.5 unloader port to ensure precise system integration.

Installation and technical specifications

For proper installation, technicians should verify the through drive configuration and port alignments against the existing unit. Given the water-cooled valve plate and ESS feature integration, ensure all coolant lines are clear and connections are tightened to prevent leaks during high-pressure cycles.

Maintenance and selection guidance

Always verify that the mounting flange and drive gear match the original equipment requirements to avoid system mismatching. Consult your authorized distributor to confirm exact fitment for your specific engine configuration.
