85000396 Compatible Volvo NH12 Air Compressor

What does a twin cylinder compressor do?

This twin cylinder compressor is a vital component of the pneumatic braking system, responsible for generating the pressurized air required for reliable braking performance. Designed for heavy commercial vehicles, this unit utilizes two piston-cylinder assemblies to provide efficient air delivery and consistent pressure levels under demanding operating conditions.

Compatibility with Volvo NH12 models

Specifically engineered for Volvo NH12 models including the 340, 380, 420, and 460 variants, this component ensures optimal system pressure. The unit features a Ø85.00 mm cylinder bore and a 62 mm stroke, providing a swept volume of 704cm³ per cycle to meet the high air demands of heavy-duty truck applications.

Technical specifications and installation

The assembly is a water-cooled type with water inlet and outlet ports measuring M16x1,5. It includes an integrated air unloader port (M12x1) and an air outlet port (M26x1,5). For technicians performing maintenance, ensure all connections are secure and cooling lines are free of obstructions to maintain peak performance.

Maintenance and troubleshooting

Regular inspection of the water-cooled valve plate and unloader ports can help prevent system pressure drops. This component is built with high-strength components to withstand the rigorous thermal and mechanical stresses inherent in heavy commercial vehicle service.
