There is a good option when a full size compressor is not an option, because of space, power supply, cost, etc.
Small commercial artist shops have an airbrush compressor. About one - two pounds, flexible hose about 6 foot, and a small air brush nozzle for pinpint control. Go for about a hundred bucks.
I use one for blowing out dirt off guns, and fluids out of guns after ultrasonic cleaning. Debris off the bench, etc.. I have used it for blowing off extra powder from the shell plate and base on the Star. Easily portable and works well. It is quiet, and takes up little room.
