If you have skill with building your own stuff, consider a
compressor out of an air conditioner, or refrigerator. Fairly
quiet, and delivers good pressure. You may be able to get a HVAC
guy to sell you an old one, cheap. You'd need to change the
lubricating oil. Replace it with an equal volume of ND30. Make
some kind of check valve, and a bleeder so that the compressor
doesn't start under load. Use an old water heater tank for an
expansion tank.

I know at least a couple repair garages where you can't hear
yourself think when the chug chug compressor comes on. Wish they
would use a refrigeration compressor instead. Actually, I may
suggest that to a couple of them.

That might be OK for home/hobby use, but you would need one hell of a
large AC compressor to supply the 15 - 20 or more cfm @100 psi or more
that is typical of an automotice repair shop.
