I want to step up to an airbrush system, but having a hard time choosing what to buy. I need not only the airbrush itself, but also a compressor and all the little bits and pieces to go. Is there some nice kits out there?
Jan you'll need an AirBrush, Compressor, Hose, Regulator and Water Trap. It wouldn't hurt to put a second small water trap at the AirBrush.
What is the recommended pressure? How much airflow from the compressor (is 23 litre/min good enough?)
You need at least 35psi from the Compressor. I paint at about 25psi, sometimes less and sometimes more depending on what is coming out of my Gun.
To my understanding a dual action is the best choice, but it seems to me that it can be hard to make a consistent spray, giving you can regulate both air and paint.
I would suggest for anyone to start by using a double action airbrush. The guns are better made and atomize paint much finer.
I have several AirBrush Guns and when I used my first double action I wished I had started out with one.
A decent double action gun is only a few bucks more than a single action and still within your $300 total budget.
Does any have a set-srew or something that makes me able to adjust the paint-/airflow?
Good point! Yes, any double action gun can be set to maintain a consistent paint flow. Better guns can be purchased that have an additional set screw (mac screw) below the front of the gun making even further adjustments possible.
Budget is about $2-300 for a complete set (if possible)
I've got a couple of AirBrush Tutorials on an AirBrush Forum Site about Guns and Compressors and links to find them.
I'll try to find the links and in the meantime I'm sure you'll get lots of recommendations from AirBrushers here.
