sf6 Pressure and vacuum units with return system

This system configuration also allows the filling of the test objects with SF6 gas in the test chamber and subsequent recovery of the gas. However, with atmospheric pressure, the test duration is on average 10 – 30 times longer as the increase in concentration for atmospheric pressure is significantly lower.

  • SF6 gas recovery unit - AGRU-8 series

    More about SF6 Gas recovery units from AGRU-8 series: SF6 gas is a great electrical insulator. Employing SF6 gas in switchgears is found to be a more effective method than relying on air or vacuum for dielectric functions. SF6 gas not only provides insulation, it provides the kind of stable operation at routine pressure levels that vacuum cannot provide.

  • The Fundamentals of Vacuum Theory

    Aug 10, 2018 · The manner in which a gas flows in a vacuum system is dependent on the gas pressure. At rough vacuum pressures above approximately 1 mbar (.015 PSI), continuum (or viscous) flow prevails. At these pressures, the molecules are relatively close together, and their collisions more frequent. Therefore flow is governed by interaction between molecules.
