Description

What does a twin cylinder compressor do?

This twin cylinder compressor serves as a critical component in the air brake system of heavy commercial vehicles, generating compressed air through two piston-cylinder assemblies. By utilizing two compression strokes per crankshaft revolution, this unit provides a higher air output than single-cylinder alternatives, allowing for faster reservoir filling. It is constructed from heavy-duty grade materials to withstand rigorous operating conditions in demanding environments.

Compatibility with Volvo NH12

This specific unit is designed for Volvo NH12 trucks equipped with D12A engines. It features a water-cooled architecture with a Ø88.00 cylinder bore and a 50 mm stroke. The unit includes an ESS feature and is compatible with Volvo OE specifications, ensuring precise integration into the vehicle's pneumatic system.

Installation and maintenance guidance

When performing installation or maintenance, technicians should verify the water inlet and outlet ports (M16x1,5) and the air unloader port (M22x1,5). Ensuring that the through drive and mounting flange match the existing setup is essential for proper operation. Always check the air inlet (Ø29) and outlet (M26x1,5) connections during assembly to prevent leaks.

Troubleshooting air supply issues

If you experience slow air pressure buildup or frequent unloading, inspect the valve plate and cooling lines for obstructions or wear.
