CAMCO 91-40 Plus Is Applicable in a Variety of Demanding Applications

Product Description

A combination of premium synthetic and semi-synthetic fluids with a combination of premium additives. Used in applications where an improved degree of oxidative stability, higher temperature performance, low volatility and seal conditioning is required. Meets the viscosity requirements of most major screw compressor OEMs.

Formulated for extended life in flooded screw compressors, certain vacuum pump applications, and general applications where a high quality lubricant with excellent oxidative, rust, and corrosion inhibited product is required. Provides improved cleanliness, low foaming characteristics, good water separation, and improved compatibility with elastomers and seals.

Typical drain intervals are up to four times that of conventional mineral oils rotary screw air compressors under normal operating conditions, and one year drain intervals possible. These products typically outperform competitor’s group II and III type semisynthetic compressor oils, including many that claim one year.

A lubricant analytical program is suggested to maximize the drain intervals. Life expectancy is dependent on operating and environmental conditions. Other viscosity grades and formulations are available for specific applications. These products have lower volatility than mineral oils, and have improved compatibility with systems designed for use with mineral oils.
