1900 020 001 BMC Compatible Twin Cylinder Compressor

What does a twin cylinder compressor do?

This twin cylinder compressor serves as a critical engine-driven component within the air brake system of heavy commercial vehicles. By utilizing two piston-cylinder assemblies, it generates the high-volume compressed air required for efficient braking and pneumatic operations. This specific model is engineered with high-strength components to withstand the demanding thermal and mechanical stresses of heavy-duty service.

Vehicle and engine compatibility

The unit is designed for compatibility with BMC vehicles and functions effectively within systems requiring high air output. It features a water-cooled design to manage operating temperatures, a Ø75.00 cylinder bore, and a 38mm stroke. This configuration ensures rapid reservoir filling and consistent pressure delivery for heavy-duty applications.

Installation and maintenance guidance

For proper maintenance, technicians should inspect the water inlet and outlet ports, which feature 1/2"-14 NPT connections, to ensure no leaks are present in the cooling circuit. Regular checks of the unloader port and valve plate integrity are recommended to maintain optimal performance and prevent system pressure drops.

System performance and selection

When replacing this unit, ensure that the mounting interface and through-drive configuration match the existing installation to guarantee seamless integration into the vehicle's pneumatic architecture.
