A no.3 nozzle airbrush set by Paasche USA come with a PU hose, spanner, bottle, valve for aerosol pressure can and a double action air brush. By pressing the trigger button air is released to clear any remaining colors. Pulling back the depressed button, color will be released. Practice by varying the distance of the nozzle to the canvas for different spray patterns. Paint volume control is through adjustment of the wheel next to the trigger button.
Keep air brush clean after use by flushing a brush cleaner through its nozzle until traces of colors are cleared.
