In many applications, particularly those with high temperature or aggressive chemical environments, the use of synthetic lubricants like perfluoropolyether (PFPE) offers superior characteristics compared to mineral oil. PFPE fluids are free of additives, chemically inert, and thermally stable. If you are operating a Leybold vacuum pump, please consult us at Intlvac Inc to learn if your application is suitable for the use of PFPE fluid.
