Be very carefull compressing breathing air. There are
serious safety risks that may not be obvious. For example,
even at normal shop air pressure, the heat of compression
can partially partially decompose compressor lubricating
oil that gets into the air stream. The result is carbon
monoxide... There is also a form of pneumonia that is
caused by the fine oil mist often found in shop air. I
don't know enough about these risks to evaluate them, but
I do know that compressing breathing air, even at relatively
low pressures, is not the kind of project that you want to
treat casually. You really have to do your homework, or
pay someone else to do it for you.
