|
| They've been making Oxygen generators for years for medical uses,
| and the Nitrogen tire filling craze is upon us... And both gases
are
| used a lot in the home shop and small industrial settings, too.
|
| And Murphy has it rigged that you always seem to run out of gas at
| the worst possible moment, like 5 minutes after the local supplier
has
| closed for the weekend. Or you live on an island, or on top of a
| mountain three hours out of the closest town...
|
| But the only price I can find for a small PSA Nitrogen system is
| $5,000 from Ingersoll-Rand, and nothing on Oxygen system pricing
| (though I didn't look that hard on that side).
|
| And since the system is basically passing the one gas through to
the
| storage tank, and adsorbing and throwing out the other, couldn't you
| use one machine, two storage tanks, and have them both?
Conveniently
| separated, the Oxygen stored at anything above 50 PSI which is
plenty
| for welding and cutting, and the Nitrogen for tires and a
shield/purge
| gas?
|
| And since it's for shop use, neither gas needs to be 99.999+% pure,
| or USP certified, or rated for gas chromatography machine usage - it
| just has to work, and not take up an acre of floor space. That
should
| lower the price significantly. Let the buyer supply their own two
| stage compressor and air dryer, any decent shop needs them anyway.
|
| There's a market niche to be filled here... Harbor Freight,
| Northern Tool, are you listening?
