Airbrushes - Differences

Before choosing an airbrush ask yourself: What will it be used for? How often will I use it? What type of material will I be spraying? What kind of paint will I be using? Will you be using a can of air or compressor?

Make sure to hold the airbrush in your hand to feel the weight & balance. If it is too heavy your hand will easily tire or cramp and affect how you paint.

INTERNAL MIX - the air and paint mix inside the airbrush giving an atomized 'fine dot' spray pattern.
EXTERNAL MIX - the air and paint mix outside the airbrush making a larger, coarser spray pattern.
DUAL ACTION - the trigger on the airbrush controls both the air and paint seperatly. this allows for different line widths when spraying.
SINGLE ACTION - the trigger only controls the air flow. Turning the needle adjustment screw gives a pre-set amount of paint when pressing the trigger.
GRAVITY FEED - a top-mounted colour cup uses gravity to draw the paint into the airbrush. (this one is great if using a can of air with your brush)
BOTTOM FEED - the paint enters through a tube or colour cup attached to the bottom of the airbrush. This requires a high PSI so a compressor drived airbrush is better.
SIDE FEED - uses a small colour cup that fits into the side of the airbrush. This requires at least 20 PSI and either air method is OK for this one.


The needles and nozzles come in varying sizes to accomodate many different projects on many different materials. Come in and see us for great books, DVD's and knowledgeable staff.
