Pure nitrogen hydrogen air machine Introduction:

Combined three gas generators, N2/H2/Air generator is a perfect machine which combines to produce pure nitrogen,hydrogen and air. Compact size, easy operation. It is an idea gases resource. Could be used with kinds of gas chromatographs and other analysis instruments. 


this machine produce pure nitrogen, pure hydrogen, pure air at the same time.



daily only use water and electricity. the ture oilfree compressor inside.



1. Nitrogen is produced through water electrolysis technologyuse qualified membrane which is widely used in spaceflight electrolysis instrument. N2 output purity is stable.

2. Hydrogen is produced also by water electrolysis technology. Through electrolysis water under KOH catalyst, to get pure H2 gas.

3. Air is powered by whole sealing silent air compressor. After purification, water,oil,dust and impurities are removed. Through pressure stable system, pure and silent 

air is finally produced under stable pressure. Use imported compressor inside without oil.

  It is an ideal equipment to replace high pressure gas cylinders.


Oilfree air compressor inside, imported from abroad.

This machine produce separately N2, H2, air at same time!
