PFPE Vacuum Pump Oil

Perfluoropolyether (PFPE) vacuum pump oils are inert fluids composed exclusively of carbon, fluorine, and oxygen atoms within their molecular structure. These oils are particularly well-suited for use in vacuum pumps, serving both as effective sealing and lubricating fluids as well as working mediums. They excel in environments exposed to highly oxidative agents such as oxygen, ozone, and nitrogen oxides, as well as reactive substances including halogens and hydrogen halides. Due to their exceptional stability and safety, PFPE vacuum pump oils demonstrate unparalleled reliability even under extreme operating conditions, making them the ideal choice for demanding applications.
