I googled it and can't find much / am at work and should be doing other things. I have a 6(?) gallon hitachi air compressor in my shop to run nail guns, etc. Could I attach this to an airbrush, or is that a silly idea and way overpowered? I keep looking at fancy painting threads (Looking at you Spiralingcadaver) and think I should give it a go, and on the cheap to start would be okay.

You'd need a regulator for pressure and a moisture catcher in line.

I know a guy who uses a commercial sprayer for furniture, and then dials down the pressure for models.

Great news! It already has a pressure regulator. I just have to check if it is low enough. I definitely need a filter though. Thanks Kt - u -rock. lolololol

Home Depot has them. If they exist in the great whit north.

You can use a one gallon but defiantly get the filter. You should be able to get one at Hobby Lobby. They have a good selection of air brush supplies. The only issue I've ever had with using a tank compressor or compressed air is loss of spay consistency when you begin to run out of air in the tank.

Most airbrush users use between 15-30 psi at any given time. If your compressor can get as low as 15 then you are good. I use a 3 gallon tank and it takes me a while to run through the air - a 6 gallon would give you a ton of air to work with.

As for a moisture trap, you can get one that attaches to your airbrush too if you cannot find one that attaches to your compressor. Currently I use this:


I like it because it acts as a rest/grip for your hand so it doesn't tire out.
