Nitrogen generators and oxygen generators operate with the PSA principle (pressure swing absorption) to produce a continuous flow of nitrogen or oxygen from the compressed air filtration: we remind you that air is composed of 78% nitrogen , for 20.8% of oxygen the rest by traces of other gases (argon, helium, hydrogen ...)
You do not want to buy? Do you prefer a lease agreement? Now you can! You can still have the gas you need without purchasing the system, but only to lease it, or only paying the gas you consume.
