We have obtained oxygen generation with two columns around 93-95% using the setup that has been given here at 1.5-3 bar pressure. We used Li-based zeolite.
However, we are facing a challenge that there is a fluctuation in the generation from 30-95% in 4-5 mins followed by 95-30% in the next 4-5 mins. So would like to know if you have observed any such behavior when running the system for longer duration.
Any help is much appreciated.
