Air Tool Oil is a low zinc antiwear circulating oil meeting Denison HF-0 requirements. It is produced from highly refined lubricating base stocks and hydraulic oil additive packages. These products are designed for hydraulic systems with higher make up rates or those, which operate at moderate temperatures. The additives found in Air Tool Oil enhance the anti-wear characteristics of the fluid. They also inhibit foam from forming in the oil and offer a moderate level of protection against rust and corrosion in the event of water contamination. Air Tool Oil is suitable for applications used in equipment located in underground mines, industrial hygiene units, and other hydraulic & pneumatic systems.
