  • SF6 Portable Gas Systems — BaronUSA

    SF6 Portable Gas Systems — BaronUSA. DESCRIPTION: Baron USA SF6 gas units are designed for efficient removal, purification, storage and recharging of SF6 gas used in circuit breakers and other switch gear. SF6 gas is pumped using an oil-less compressor system to prevent oil contamination of the gas. Gas liquefaction is achieved by pressurization thereby eliminating the need for refrigeration equipment .

  • Dilo SF6 Gas Mobile Vacuum Pump Units B046R20 | CEPCO Sales

    B046R20. This vacuum pump unit is “powerful” – its nominal suction capacity is 200 m³/h at 50 Hz for quick and reliable evacuation of air to a final vacuum of 1 mbar. This unit is particularly suitable for the evacuation of large gas compartments. Two coupling connections (DN20 and DN40) allow the evacuation of two gas compartments at the same time without any manifold that means more efficiency and higher productivity during operation.
