Description

The precision-engineered Twin Cylinder, Air Compressor is a critical component designed to maintain consistent pneumatic pressure within the braking system. This water-cooled unit ensures optimal thermal management during heavy-duty operation, providing reliable air supply for heavy commercial vehicle systems.

The 85000491 is the OE equivalent of the VOLVO 85000491 air compressor used in VOLVO vehicles. This high-strength component features a cylinder bore of Ø85.00 and a stroke of 62 mm, delivering a swept volume of 704cm³. It is specifically designed for compatibility with high-demand industrial environments.

For workshop technicians, this unit offers streamlined installation with an M26x1,5 air outlet port and an M12x1,5 unloader port. The integrated water-cooled valve plate and ESS feature support long-term durability and stable performance under varying thermal loads.

Regular maintenance of the air compressor system is essential to prevent pneumatic failures. Technicians should monitor the water inlet and outlet ports (M16x1,5) to ensure efficient cooling and prevent overheating during operation.
