Omnilube food-grade (H1) compressor lubricants are said to provide better lubricity and protection against wear, and be less susceptible to oxidation, than other H1 food-grade synthetic lubricants. Omnilube 32/46, 68, and 455 are formulated from high-quality polyalphaolefin (PAO) base oils and a proprietary additive package to achieve long life. The three oils are designed for rotary-screw compressors and, depending on the screw design, can have a service life of up to 8,000 h. Omnilube 455 can be used in reciprocating compressors. Other advantages of the oils include lower varnish formation, low pour point and high flashpoint, and excellent compatibility with elastomers, plastics, and paints. Field tests have shown the lubricants to outlast other synthetic H1 lubricants by 50–100%. Omnilube food-grade products meet the requirements of U.S. Dept. of Agriculture and Food and Drug Administration regulations (21 CFR 178.3570), conform to the requirements of NSF International, and are approved by the Orthodox Union for Kosher use.
