message: While the effort to include an animation is laudable it has not been successful since it seems to illustrate some type of fully continuous process, not a cyclic pressure swing process.150.227.15.253 (talk) 13:45, 11 October 2021 (UTC)
thread_title:  Animation 

message: Oxygen concentrators and oxygen generators are not the same thing at all.
Oxygen generators are small canisters, used in commercial aircraft and spacecraft to "generate" oxygen and heat.  These are the canisters which ignited and caused the fire on the ValuJet flight in Florida.
The develpment of the oxygen generator is held by a Dr Hwoschinsky.  —Preceding unsigned comment added by 151.200.152.113 (talk) 18:53, 6 September 2008 (UTC)
thread_title: Difference

message: The flowrates with associated rated percentage of oxygen given in the article are likely to confuse people, as they seem to represent the oxygen concentration coming out of the machine, which doesn't make sense since one would expect a machine to be able to deliver higher oxygen content at lower flow rates. 
In fact, these figures represent the oxygen concentration the patient breaths when using for example nasal cannula attached to the machine. The output of the machine mixes with the ambient air when a patient inhales. The oxygen delivered while the patient exhales or pauses is not used. 
Say for example the machine delivers 2 liters per minute, the respiratory minute volume is 10 liters and the patient inhales 50% of the time, then the total amount inhaled will be 1 liter from the machine (50% of the output) and 9 liters ambient air. 84.197.185.192 (talk) 13:28, 9 August 2011 (UTC)
thread_title:  How they work 

message: The articles on PSA oxygen generators, oxygen concentrators and oxygen plants should be merged into oxygen enrichment. The article on gas separation needs some work too, there is probably some merging that could be done with it.Testem (talk) 13:22, 18 September 2013 (UTC)
replies: text: I have made the page on gas separation into a summary page of various techniques. I created a new article for its old content, which only covered membrane technologyTestem (talk) 11:05, 24 September 2013 (UTC)

thread_title: Redundant article

message: The PSA oxygen generator page is particularly thin on content and has much overlap. It should be moved first into this one, then have the overlap removed before further merging.Testem (talk) 11:05, 24 September 2013 (UTC)

thread_title: Merger proposal

message: This article needs information on alternative methods of oxygen concentration, such as membrane technology. I know that other approaches are rarely used for insitu concentration but the article title implies it covers all possible methods when it does not.Testem (talk) 13:08, 1 October 2013 (UTC)
thread_title: Missing information

message: The article (Jan 19, 2015) claims that radon gas is present in the "near pure oxygen". I challenge both of these assertions. I have some familiarity with zeolites, and I doubt that a 80:20 mixture can be reduced to a 1:99 mixture in a reasonable number of steps using such technology. Hence, I doubt the gas present is nearly "pure" oxygen. Moreover, radon may or may not be absorbed by the zeolite, IDK, but it certainly isn't a significant amount UNLESS the intake air has a significant amount it it. I expect that the zeolite's selectivity for N2 is only moderate, so I suspect this section is advertising hyperbole, not scientific measurement. Anyway, the composition in the cylinder is EASILY measured, the fact that this article provides no such measurements raises an enormous RED FLAG about its trustworthness. It is also true that for those species (radon?) which are not absorbed, they will be concentrated, and this includes ALL pollutants. Radon is such a trivial component of most air, that it doesn't merit inclusion. I also question the claim that water vapor is present in a "small amount", but I don't know what the selectivity is of the zeolite. Clearly, the H2O molecule is much smaller than N2, but what effect the dipole effects have on absorption depend on the particulars of the interaction. I'd be happy to be proved wrong here, where are the citations and what are the facts??Abitslow (talk) 20:42, 19 January 2015 (UTC)
