KRYTOX 1506 Vacuum Pump Fluid by TMC Industries
The KRYTOX 1506 Vacuum Pump Fluid from TMC Industries, supplied by Econtrol Devices, is developed for applications where conventional vacuum pump oils create safety, waste disposal, and maintenance concerns. This vacuum pump fluid is nonflammable, eliminating the chance of fire in pumps, and is non-reactive, making it safe for use in oxygen systems. It can replace competitive PFPE fluids as well as other types of vacuum pump fluids used in industrial applications. Unlike many conventional fluids, Krytox vacuum pump fluids do not contain acetal groups that are susceptible to attack by Lewis acids, providing superior stability in demanding vacuum environments. The fluid is precisely distilled to deliver low vapor pressure and reliable performance while also being recyclable.
KRYTOX 1506 Vacuum Pump Fluid is designed for applications requiring dependable performance and low vapor pressure. The product supports industrial vacuum systems where contamination control and operational reliability are important. Its recyclable formulation allows used fluid to be reclaimed and reused, supporting efficient maintenance practices.
Applications
KRYTOX 1506 Vacuum Pump Fluid is recommended for a wide range of industrial vacuum applications, including:
- Vacuum pumps
- Plasma processing
- Chemical Vapor Deposition (CVD) operations
- Semiconductor manufacturing environments where process chemicals can attack conventional lubricants
- Vacuum system valves, seals, bearings, and connectors requiring low vapor pressure, low outgassing, and contamination tolerance
- Edwards Root blowers EH250–EH4200, QMB Series, and HV Series
- Replacement for Fomblin 14/6, Leybold HE1600, Halocarbon 56, and Castrol Braycote 1723/1723+
