If your application requires your Roots blowers to use food grade oil, we have several options available. These synthetic lubricants meet the H1 requirements for food grade lubricant.
Originally created by the USDA, the lubricant safety standards are now determined by the National Sanitation Foundation (NSF) in accordance with guidelines from the Global Food Safety Initiative and the FDA’s Food Safety Modernization Act. The NSF classifies lubricants into one of three categories: H1, H2, and H3.
H1 lubricants are what most people refer to as “food grade” lubricants. They may be used in applications where incidental food contact may potentially occur. This contact is limited to a trace amount–no more than 10 parts per million (0.001%)–or else the food is deemed unsafe for consumption. H1 lubricant formulations may only contain certain base stocks, additives and thickeners as specified by FDA regulations (21 CFR 178.3750).
