I just got a Grex Airbrush compressor for my airbrush. My big compressor is still down so I wondered if this little guy would handle my Harbour Frieght touch up gun that I use to spray lacquer on smaller pieces. I cranked the power up to 35PSI and it works perfectly. It does have to power up each time I pull the trigger but it seems to keep up. I didn't see the pressure drop at all. I had to do some jury rigging to make all the fittings work but nothing spectacular. I don't have a spray booth so I spray out the door. Seemed to work fine.
