Let's try to ignore all of the irrelavent BS that was recently posted to
this topic. An oil less air compressor is perfectly safe to use with a
simple filter to trap any particles that get through.

But your stock dive regulator won't work. It is designed to work with about
200 psi air supply. A typical Home Depot oil less compressor won't supply
enough pressure.

You need a "hookah" regulator that will work with about 25-50 psi supply
air. I bought mine from an outfit that sells equipment for small scale gold
mining. Google around and you should find one.
