Abstract: A lubricant for reducing or eliminating airborne lubricant exhaust mist in ambient air when used by a tool driven by compressed air. The lubricant includes between about 58 vol % and about 90 vol % polyalphaolefin or polyalphaolefin blend, and between about 10 vol % and about 42 vol % complex ester compatible with the polyalphaolefin or polyalphaolefin blend. The ester includes polymeric molecules with a cohesive tendency to adhere to each other, and when subjected to shear stresses, to form elongate filaments.

Abstract: An air tool or air motor lubricant for adding to compressed air, and the method of operating air tools with the lubricant, in which the lubricant comprises a mixture of a polyalphaolefin or polyalphaolefin blend having a viscosity in the range of 2 to 3000 cSt and a high molecular weight complex ester in a ratio of 1.3:1 to 20:1 of the polyalphaolefin or polyalphaolefin blend to the high molecular weight complex ester. The lubricant comprises about 58 to 90 vol % polyalphaolefin or polyalphaolefin blend and about 10 to 42 vol % high molecular weight complex ester. The mixture of polyalphaolefin or polyalphaolefin blend and high molecular weight complex ester is added in an amount in the air of about 0.2 to 0.6 ppm effective to generate a lubricant airborne mist concentration in exhaust air of 0.2 ppm or less.
