Understanding Airbrushes

There are 2 types of airbrushes –

1. Single Action.

By pressing down on the trigger, both the air and paint come out of the airbrush. To adjust the amount of paint flowing through the airbrush, you will need to adjust the knob at the back of the airbrush. You will need to continuously turn the knob for different airbrushing levels - from little spray from working close, to more spray when airbrushing further away.

2. Dual Action.

Pressing down on the trigger releases the air through the airbrush and by pulling back the trigger at the same time the paint will be released. The amount of paint released is controlled by how far back you pull the trigger.

These airbrushes can be further divided into 3 styles that relate to how the paint is stored in the airbrush.

(i) Siphon Feed where the paint is stored in a bottle under the airbrush

(ii) Side Feed where the paint is stored in a cup on the side of the airbrush side feed airbrush
(iii) Gravity Feed where the paint is stored in a well or cup on the top of the airbrush

Paint Tip

Each different brand of airbrush has their own sizes. It is recommended that you use the “medium” size. The “small” sizes are usually used for inks.

Needle

It is also best to purchase an airbrush whose needle can tolerate being brushed clean with a nail brush without damaging it. You will find cleaning between different colours much quicker when a brush can be used.

Whatever brand you decide upon make sure it includes a warranty, repairs are available in Australia, parts are easily obtainable and the cost of those parts are reasonable. Some airbrushes are average price, but their spare parts are very expensive. Also, if purchasing overseas, the warranty conditions ie. if faulty do you have to return to country of purchase at your own expense.
