20775224 Compatible Compressor for Volvo D12C Engines

What does a twin cylinder compressor do?

This twin cylinder compressor plays a critical role in the pneumatic braking system by providing a steady supply of compressed air. Engineered with high-strength components, it is designed to withstand the rigorous thermal and mechanical stresses found in heavy commercial vehicle applications. The unit features a through-drive design and a water-cooled valve plate to maintain optimal operating temperatures during continuous service.

Compatible vehicles and engines

This specific model is compatible with Volvo FM12 trucks equipped with D12C engines. It is designed to meet the demanding requirements of the braking system in these heavy-duty vehicles. The unit's technical configuration includes an M26x1,5 air outlet port and an M16x1,5 water inlet/outlet port to ensure seamless integration into existing pneumatic and cooling circuits.

Installation and maintenance

When performing maintenance or replacement, technicians should verify the air inlet port diameter of Ø35 and the unloader port specifications. Ensuring that the water cooling lines are clear and properly connected to the M16x1,5 ports is essential for preventing overheating. Regular inspection of the valve plate and seals helps maintain consistent air delivery and system pressure.

Troubleshooting and selection

Proper selection ensures that the air brake system functions correctly under load. This compressor's 704cm³ swept volume provides sufficient capacity for maintaining pressure in large-scale pneumatic systems used in heavy commercial transport.
