When choosing an airbrush compressor keep in mind that put airbrush art onto t-shirts does require a high psi. The psi setting should be between 40 to 60. Make sure that your compressor is rated for the type of work you are going to be doing. In this case it will be airbrushing t-shirts. When doing airbrush art onto t-shirts as a business then invest in a commercial air compressor. The trigger will control the air and the amount of paint that comes out is determined by the needle adjustment on the back of the airbrush handle. Dual action is when the trigger on the airbrush controls both the air and paint. The trigger is pressed down for the air and back for the paint. Now when it comes to the feed on the airbrush there are three types of feeds that you can choose from. This is also the choice for airbrushing t-shirts as well. But as long as your project is made from the above material you can use water soluble acrylics for your airbrush art designs. Depending on which brand of acrylic paint that you go with, you may need to thin it down so that it flows freely through the airbrush.
