What does a twin cylinder compressor do?

This twin cylinder compressor serves as a critical component within the pneumatic braking system, converting engine power into high-pressure compressed air. Built with high-strength components, it is specifically designed to meet the rigorous demands of heavy commercial vehicle operation, ensuring consistent air supply for braking and auxiliary systems.

Compatible vehicles and engines

This unit is compatible with Volvo FH13 trucks equipped with D13A engines. It features a through-drive design and is specifically configured for water-cooled systems to maintain optimal operating temperatures during long-haul service. The technical configuration includes a Ø85.00 mm bore, a 56 mm stroke, and an air inlet port of Ø35.

Installation and maintenance

For correct installation, technicians should verify the water inlet and outlet ports (M16x1,5) and the air outlet port (M26x1,5) match the existing system configuration.
