21353433 Compatible FM II Single Cylinder Compressor

What does a single cylinder compressor do?

This single cylinder compressor serves as a critical component within the pneumatic braking system, providing the necessary compressed air for vehicle deceleration and auxiliary functions. Engineered with high-strength components, it is designed to withstand the rigorous thermal and pressure demands of heavy commercial vehicle operations.

Compatible Volvo FM series vehicles

This unit is specifically compatible with Volvo FM and FM II models, including variants such as the FM 300, FM 420, and FM 500. It is engineered to function seamlessly within the air brake systems of these heavy-duty trucks, ensuring consistent air supply for safety-critical operations.

Technical specifications and installation

Technical specifications include a 318cm³ swept volume and an air inlet port of Ø35. For proper installation, technicians should verify the water cooling connections via the M16x1,5 inlet and outlet ports. This water-cooled design helps maintain optimal operating temperatures during extended use.

Maintenance and troubleshooting

To ensure long-term reliability, regular inspection of the water-cooled valve plate and unloader port (M12x1,5) is recommended during routine maintenance intervals. Maintaining clean coolant flow prevents overheating and preserves the efficiency of the piston assembly.
