The BLACK BEAR AW ASHLESS SERIES are highly refined ashless anti-wear hydraulic oils,  developed to meet the requirements of high pressure hydraulic systems.  These zinc-free oils are designed for use in vane, rotary, gear pumps, and compressors, along with circulating systems and machine tools.  These oils are characterized by outstanding performance in preventing rust, oxidation, foaming, air entrainment and many other factors that occur in hydraulic systems. This fluid is non toxic and recommended for applications where the use of oils containing toxic heavy metals is restricted because of soil or water contamination.  The additive system in these oils is approved as meeting the requirements of pump manufacturers and machine tool builders.  These products have good oxidation resistance, detergency properties, rust and corrosion protection, as well as resistance to foaming.  The unique additives used in our AW ASHLESS SERIES also allows for better detergency properties that prevent varnish buildup in sophisticated systems.
