Description

This high-strength component is designed to provide consistent air pressure within the vehicle's pneumatic system. As a critical part of the air brake compressor assembly, it ensures the reliable delivery of compressed air required for heavy commercial vehicle safety and operational efficiency.

85000491 is the OE-equivalent of the VOLVO 85000491 Twin Cylinder, Air Compressor used in VOLVO heavy commercial vehicles. This part is specifically engineered to meet the rigorous demands of professional transport environments, maintaining structural integrity under high-pressure cycles.

The assembly features a water-cooled design to optimize thermal management during continuous operation. It includes a technical configuration with a Ø85.00 cylinder bore and a 62 mm stroke, ensuring precise volumetric output. Workshop technicians should verify the water inlet and outlet ports (M16x1,5) and the air unloader port (M12x1,5) during installation to ensure seamless integration with the existing cooling system.

For optimal service life, regular inspection of the air-cooled components and the water-cooled valve plate is recommended. This twin-cylinder unit is built for heavy-duty grade performance, providing a stable pneumatic foundation for the vehicle's braking and suspension systems.
