85000329 Compressor Compatible with Volvo NH12

What does a twin cylinder compressor do?

This twin cylinder compressor is a critical component in the air brake system of heavy commercial vehicles, designed to generate the high-pressure compressed air required for reliable braking performance. Utilizing two piston-cylinder assemblies, this unit ensures efficient air production and rapid reservoir filling to maintain consistent system pressure during operation.

Compatibility with Volvo NH12 engines

Specifically engineered for Volvo NH12 models, including NH 12/340, NH 12/380, NH 12/420, and NH 12/460, this component is built to meet stringent heavy-duty requirements. It features a water-cooled design with an M16x1,5 inlet and outlet to manage operating temperatures effectively under continuous load.

Technical specifications and maintenance

Maintenance technicians should note the technical specifications: this unit has a Ø85.00 cylinder bore and a 62 mm stroke, providing a swept volume of 704cm³. The air outlet port is M26x1,5, and it includes an ESS feature for optimized system integration. Regular inspection of the water cooling ports and unloader valves is recommended to prevent pressure fluctuations.

Installation and system integration

When replacing this component, ensure the mounting interface and through drive configuration match the existing installation to avoid air leaks or mechanical misalignment in the pneumatic circuit.
