EQUIVIS AF is a zinc-free" high performance hydraulic fluid for:- all kind of hydraulic systems operating under high pressure (limit as indicated by the pump manufacturer) and high temperature (up to 100°C in hot points)- hydraulic systems working under extreme temperature variations and equipment operating outside : easy start up at low temperature (-30°C) and regular operating in all seasons : civil engineering, agriculture, marine, transport and other industrial applicationsAdvantages:Very high viscosity index and shear stability for a wide range of operating temperature.Superior thermal stability avoiding the formation of sludge even at high temperature.Very good oxidation stability ensuring a long service life of the fluid.High protection against wear, rust and corrosion ensuring maximum equipment life. Excellent hydrolytic stability avoiding filter blocking.Remarkable filterability even in the presence of water.Good anti-foam and air release properties by using silicon free components.Low pour point.Good demulsibility ensuring rapid water separation.EQUIVIS AF does not contain heavy metals or zinc to avoid contributing to their accumulation in the environment."
