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

    For evacuation of air or nitrogen. 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.
