Garage sale oxygen concentrator

[alepale101]

I bought a used medical oxygen concentrator for an shamefully low price. Please don't ask how low, it's shameful. It works like a charm and it produces over .5L of oxygen per min. How will it work for aeration? At that rate, which is at the low end of its scale, how long would it take to aerate a 5 gal. batch? I will add an inline filter and a stone (either .5 micron or 2 micron). Can't wait to try it, and to taste the results.

Sorry for repeating myself. I got a message that the first post was too short.

Those typically have an inline filter on them already. You have to take off the cover and it should be in the back. Not sure how long it would take to oxygenate a batch of beer though.
