    Cool idea. I would be interested in knowing the concentration you achieve and flow rates (LPM/CFH). This wouldn't work in my workshop as we don't treat our equipment nicely enough and we don't have sparkies to tend to it.

    I wonder how this performs compared to the cheap concentrators you can get off ebay.

    Interesting, but why did the original poster link to part 2 of the thing?
