I second what Don said re: nitrogen or other dry gas. Compressors tend to
put contaminants (lubricants, generally) in the air. I happen to have
argon around for welding and for putting an inert filling in chemical and
paint containers, so I tend to use that. More expensive than nitrogen, but
I have it and the amount I use for other purposes is nearly insignificant
compared to welding.
For compressors, a cheap airbrush compressor should work. Maybe even an
aquarium/hydroponics compressor. Both of these tend to run pretty clean.
