Renewable Lubricants Bio-Food Grade air tool lubricant. A specially formulated, ultimately biodegradable1 air tool lubricant designed to replace petroleum based air tool oils. Bio-Food Grade air tool lubricant is designed to be commonly used in food processing equipment as it is essentially odorless and tasteless. Because of the super high viscosity index of the HOBS, this biobased product performs in many applications. The natural oily film of this product has shown in laboratory and field tests to out perform petroleum base oils in terms of natural lubricity. This air tool oil provides excellent lubrication for both rotary and reciprocating types of air tools, such as chipping hammers, impact wrenches, air motors, grinders, reamers, drills, etc. It can be fed through an airline lubricator or by a squirt can directly into the tool through the quick coupling air connection. Bio-Air Tool lubricant can be very effective on the lift cylinders of can fillers in breweries, bottling plants and canning plants. This product has exceptional benefits over petroleum oils in these applications because there is direct danger of polluting the air, water, soil, or work environment through loss of the lubricant.
