What is a double action airbrush?

A double-action (or dual-action) airbrush is a regular airbrush with a control button/lever that regulates both air and paint flow.

A regular airbrush has a button or lever that will start the air flowing. The resulting air stream will pick up paint as it passes a paint reservoir and a fine paint spray will be deposited through the nozzle.

A dual-action airbrush works in much the same way but the lever regulates both the air and the amount of paint that is allowed to mix with it to give greater control and precision to the modeller. This is done by pushing down and pulling back the lever at the same time.
