The air that comes out of my 58 year old compressor is definitely
unsuitable for breathing. This compressor may not be representative,
for obvious reasons.

In any case, I would try to put at least two filters in the air line
to be on the safe side. If the air does not smell after filteriing, I
would use it. as there are many cheap sources of breathing
air, there is no sense to use anything substandard.

Why would anybody screw around with breathing air? Look at the junk that
gets drained out of compressor tanks. Not what I want to breathe, unless
it's been through a big Bullard filter, and they cost a bit more than
most
of us are willing to spring for.


Those are not necessarily expensive.

I had a 5 HP Bullard breathing air pump once that I could not sell for
even $50. That was a very lucky circumstance, as I quickly realized
that I could use its 5 HP single phase motor on my old Curtis
compressor.

I think that a HVLP turbine should be acceptable for breathing air and
is a nice inexpensive package. Same with a very cheap vacuum cleaner
switched to blowing, as long as you did not use it for collecting
dust.

Again, I would not hesitate to use a compressor, if after filtering
its air does not smell of anything (and this is a big if).

5 hp would supply a lot of breathing air! The Bullard filter I was referring
to can be used with a regular tow-behind compressor, in conjunction with CO
monitoring. The setup is fairly expensive.
