85013935 Compressor compatible with Volvo FM

What does a twin cylinder compressor do?

This twin cylinder compressor serves as a critical component in the pneumatic braking system of heavy commercial vehicles. It is engineered to provide consistent air pressure required for brake actuation and auxiliary pneumatic systems. Built with high-strength components, it ensures durability under the rigorous thermal and mechanical stresses typical of long-haul operations.

Vehicle compatibility and engine fitment

This unit is specifically designed for Volvo FM models, including the FM 300, FM 340, FM 360, FM 370, FM 380, FM 390, FM 400, FM 410, FM 420, FM 430, FM 440, FM 450, and FM 460, as well as the FM 480 and FM 500 variants. It is compatible with Volvo systems and features a through-drive configuration.

Installation and maintenance guidance

For proper installation and maintenance, technicians should verify the water inlet and outlet connections (M16x1.5) to ensure efficient cooling. The unit utilizes an M26x1.5 air outlet port and an M16x1.5 unloader port. Regular checks of the cooling circuit and air inlet ports are recommended to prevent system failure.

System troubleshooting

Maintaining correct air pressure within the system helps prevent premature wear on braking components. If air pressure drops or unloader performance fluctuates, inspect the ESS feature and port seals to ensure optimal performance of the pneumatic circuit.
