Angstrom Advanced GHA-300/500 Combined Hydrogen and Air Generator


Angstrom Advanced GHA 300/500 Combined Hydrogen and Air Generator


Based on Angstrom Advanced HGH high purity hydrogen generator and Angstrom Advanced HYA air generator, GHA-series generator combines the two with great quality and user friendly design. It is a perfect combination of safety, convenience, and reliability, featuring advanced technique and stable performance.


  • Hydrogen and air can be generated together or separately
  • Air passage: since the cylinder is made of stainless steel, there is no rustic water like in generators which use carbon-steel cylinder
  • Hydrogen passage: advanced switching power supply is adopted so that efficiency of electrolysis can be highest
  • Multi-stage protective device is installed, improving effectively the safe operation of the instrument.
