These machines are gas generators fed by distilled water and electric current. They are very useful in gold industry, sunglass industry, dental units, laboratories etc.
They differ from other similar machines as the gas generator operates at a pressure  rate of 1.5 atm, higher than any other machine, thus avoiding the so-called ìfog effect”.
