Helium gas filling and AIR evacuating device
HE-3-001-4-R002A
Description

For evacuation of air and safe filling of helium gas 

This device covers two important functions.  

  • AIR evacuation 
  • Helium filling 

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 self-sealing DILO couplings guarantees handling without gas loss.
