My wife, who does Reverse Glass Painting restorations, and uses air for both cleaning and air brushing started out with my portable air gun compressor with a filter/regulator. Noisy would be an understatement.

Then I purchase a used tank-less airbrush compressor that is almost silent, with a very gentle airflow. I think is was only $25 on Craigslist. You could hook up a foot switch to it if needed.
