  • Mobile Vacuum Pumps for Evacuation of Air and Nitrogen

    The mobile vacuum pump unit is engineered for easy handling. The unit serves for evacuation of air or nitrogen from switchgear. The 40 m³/h vacuum pump enables a final vacuum of < 1 mbar. Therefore, it is guaranteed that no air / gas mixture is generated and the insulation properties of SF 6 are retained.
