is the simplest (and cheapest) type of airbrush available. It has
a single on/off trigger for the air supply. There is no control
over the amount of air drawn into the airbrush or the ratio of air
to paint while in use. Many single-action airbrushes allow adjustment
of the paint volume, but only when not spraying. To adjust the spray
pattern and the spray density while in use, the distance between
the airbrush and the work piece must be changed.
mix' single action airbrushes are the most basic. Air blowing
across the top of the paint supply tube draws the paint into the
air stream. Often the paint does not atomise completely which results
in a rather rough spray.
mix' single-action airbrushes overcome this problem by mixing
the paint with the air as it flows through the body of the airbrush.
These provide a much better spray quality and allow for more varied
spray patterns but are far more expensive. You still cannot adjust
the spray pattern and paint flow while spraying.
the single-action airbrush is great for laying flat colours, but
is a very limited tool when the best airbrushing techniques are
Double Action Airbrushes, although the most expensive, is by far
the most versatile and popular type of airbrush. It has a trigger
assembly that gives you complete control over the amount of air
flowing through the airbrush, and the amount of colour, which it
sprays. Once mastered the user can switch from the finest of washes
to a dense, solid colour in a single pass.
models have an adjusting screw or ring that fixes the trigger at
a certain point so that it can be used as a fixed double action
airbrush. This allows the presetting of a fixed spray volume, ideal
for nail artists.
airbrush, although more expensive than other types, is a tool well
worth the investment. If looked after correctly, it will serve the
user well for years to come.
