For evacuation of air and safe refilling of SF₆ into gas compartments by overpressure

This device covers two important functions: The integrated vacuum pump allows the evacuation of air down to < 1 mbar so that no air/gas mixture is produced during the subsequent filling process. The use of gastight and selfclosing DILO couplings guarantees emission-free gas handling.

The weight of the gas to be refilled can be conveniently registered (with the 3-001-4-R022 / R122 version) by means of the integrated weighing scales. The weight is indicated on the illuminated display which switches off automatically if the scales are not used for a longer period of time. Thanks to the tare function, the gas can be precisely quantified.
