SF6 Breakers evacuation for Mitsubishi

SF6 Breakers evacuation for Mitsubishi

Nominal suction capacity 495 m³/h Roots pump for evacuation of air or nitrogen This series is very powerful and allows quick evacuation of large gas compartments. A vacuum pump combined with a Roots pump enables to obtain a final vacuum of 2x 10-2 mbar. Thus, both air and moisture are removed from the circuit breakers.
