What is the difference between cylinder oxygen and medical oxygen generator?

1, at present, most of the medical oxygen is liquefied at low temperature and separated from the production, and then filled into the oxygen cylinder, the concentration of this kind of oxygen will be relatively high (more than 96%), and, in the output port of the oxygen cylinder pressure will be higher.

2. However, some of the medical oxygen is produced by large molecular sieve oxygen concentrators, so that the concentration of oxygen obtained is the same as that of small oxygen concentrators (85%-96%), but these large molecular sieve oxygen concentrators are usually equipped with pressurizing devices, so the output pressure of oxygen is relatively high.
