Forum topic about creating an oxygen concentrator to fill up oxygen bottles. A user asks: Is any one here is using or has used an oxygen concentrator. I do know you cannot get 100% pure oxygen. Basically it is a PSA oxygen concentrator that also has a compressor mounted to it that pumps direct to scuba tanks. It will also provide continuous flow for blending, but a concentrator that small doesn't put out enough for a big compressor. Several manufacturers have boosters designed for this application though. Invacare homefill, Rix microboost *yes this was actually designed around PSA oxygen concentrators*, Philips Ultrafill *only one that will go to 3000psi*, and a few others. I use one and fill 2200 psi O2 bottles to do PP blending nitrox. It's a invocare homefill set up. Makes perhaps 200+ cuft a day of 96% O2. 2 days to fill a standard 5' tall O2 bottle used for standard acetalyne rigs. These systems can be hard to get because they need a perscription to get one. but some will sell for hobby use. (glass works etc.) I think you can still get the concentrator and compuressor for about 1000 $ and then there is an adaptor hose that is needed to connect to fill tanks that may be 100 $ unless you hae one of hte designed carry around tanks to get the part from. There are other solutions of course. Keep the unit indoors or somewhere where it is dry and low humidity and the concentrator will last a long time. I will post pics of what i have if any one want s to see them. PM me.
