    It looks like nice, and 70 dB is very low noise for something compressing air.

    I am perplexed by the symbols in the video:

    Water is H2O alright, but air was not O2 last time I checked.

      That would be some dangerous air.

      A wonderful archaic technology that is also an useful thing-to-know in post-apocalyptic settings.

        Although a an apocalypse were access to compressed air sounds more like a lull than a collapse
