What does a single cylinder compressor do?

This single cylinder compressor serves as a critical component within the pneumatic braking system, providing the necessary air pressure for heavy commercial vehicle operations. Built with high-strength components, it ensures consistent performance under demanding thermal conditions through its integrated water-cooling mechanism.

Vehicle and engine compatibility

Specifically engineered for compatibility with Volvo NH12 trucks equipped with D12C engines, this unit features a Ø85.00 mm bore and a 56 mm stroke. The design includes an M26x1,5 air outlet port and an M12x1,5 unloader port to ensure precise system integration.

Installation and maintenance

For workshop technicians performing installation, this water-cooled unit requires careful connection of the M16x1,5 inlet and outlet ports to maintain thermal stability. The through-drive configuration and ESS feature support reliable operation during long-haul service intervals.

System reliability guidance

Regular inspection of the water-cooled valve plate and air ports is recommended to prevent pressure drops in the braking circuit. Consult your authorized distributor to verify exact fitment for your specific engine configuration.
