In Roots Vacuum Pump and Roots Blower in Japan│Yotsuba air

Since the VP Type pump adopts the Roots system, the rotor rotates inversely as gas flows back if the pump is stopped while the suction side is still in vacuum. To prevent such phenomenon from breaking the pump and contaminating the vacuum unit, the pump is equipped with reverse rotation prevention mechanisms as standard.Get price

Sulfur hexafluoride - Wikipedia

Sulfur hexafluoride or sulphur hexafluoride, is an extremely potent and persistent greenhouse gas that is primarily utilized as an electrical insulator and arc suppressant. It is inorganic, colorless, odorless, non-flammable, and non-toxic. SF 6 has an octahedral geometry, consisting of six fluorine atoms attached to a central sulfur atom. It is a hypervalent molecule. Typical for a nonpolar gas, SF 6 is poorly soluble in water but quite soluble in nonpolar organic solvents. It has a density ofGet price
