A good regulator (~$25 new) will knock the pressure down to airbrush levels. Be sure to look up your brush type; top feeds need very little pressure, some operate under 10 psi. Bottom feeds need more, up into the 30 psi range, and pressure for side feed is between them. Set the regulator to the right setting, then slightly adjust as needed for your particular airbrush. Also be sure to have a dryer or moisture trap on the line.

The real bonus for 'airbrush compressors' is their noise level, or rather their lack of noise. Some are extremely quiet, sounding like a loud cat purring. Of course this quietness costs more too but sometimes it is worth it. You can save money with a long length of hose to use on an existing loud tire/tool compressor so the compressor can be put it in another room or outside. If the hose has standard connectors, you also need to make or buy an adapter into the smaller airbrush hose size.
