Description
EnviroLogic 122 hydraulic fluid is a readily biodegradable and non-hazardous ISO 22 viscosity grade hydraulic oil for use in general purpose hydraulic systems. EnviroLogic 122 is based on unique biodegradable base oil technology and is a direct replacement for petroleum oil based hydraulic fluids. EnviroLogic 122 is formulated for high anti-wear performance, excellent water separation, low foaming and air release characteristics, excellent corrosion and rust protection, and high oxidative stability for long fluid use. It also has a high viscosity index and will permit fluid operation over an extremely broad temperature range. EnviroLogic 122 will meet or exceed the performance of petroleum hydraulic fluids and will meet the requirements of virtually all major pump manufacturers.
