Basic airbrush information
dealing with airbrushes made by the leading airbrush manufactures
Badger,Paasche,Iwata,Grex,Harder Steenbeck and more.
Airbrushes can be
either internal or external mix, single action or double (dual) action.
SOME AIRBRUSH
DEFINITIONS
EXTERNAL MIX -
Combine air and paint after they exit the tip of the airbrush. Paint volume is
controlled by a knob on the airbrush.
INTERNAL MIX - Combine air
and paint inside the airbrush (tip actually).
ACTION - How the
trigger is used to control the airbrush functions which affect the spray
pattern of the airbrush.
SINGLE ACTION - Pushing down on the
trigger gives you both paint and air. To stop paint being applied (flowing)
just let up on the trigger. Amount of paint applied is controlled by a separate
knob (pictured below). Single action airbrushs operates much the same as a can
of spray paint but with the added ability of being able to adjust the amount of
paint applied and the air pressure. To control the amount of paint the single
action will apply when you push down on the trigger you would adjust the paint
volume adjustment knob. Turning the knob clock wise decreases paint flow and
turning it counter clockwise increases paint flow. Which means during the
painting process to adjust paint flow you must stop and adjust the paint volume
knob to increase or decrease paint flow. Very slow process painting anything in
this manner, very limiting.
The air hose would just screw onto the post
marked air hose connection in the picture below. The other end of the air hose
screws onto the compressor.

DOUBLE ACTION -
Pushing down on the trigger gives you air, pulling back on the trigger gives
you paint. The amount of air used should be controlled at your compressor
setting not by feathering the amount of pressure you apply by pressing down on
the trigger. Amount of paint applied is determined by how far back you pull the
trigger.( pictured below) This gives you ability to paint non stop and increase
or decrease paint flow simply by how much you pull the trigger back or push it
forward. Giving you much more control during the painting process than the
single action airbrush. Double action or dual action is great for applications
where constant adjustments of spray widths and volume are required. The spray
pattern as with a single action airbrush is determined by how far from the
painting surface you are. The closer you are the smaller the spray pattern the
further away you are from the painting surface the larger the spray pattern
will be.
DOUBLE OR DUAL ACTION
AIRBRUSH
Airbrush Styles
Weather it be dual action or
single action there are three different style airbrushs available. Gravity
feed, siphon feed and side feed.
Gravity feed - The most detail
oriented airbrush style available. As the paint is stored directly above the
airbrush and it is gravity that draws the paint to the needle / tip makes this
style airbrush the most consistent and responsive style airbrush. Nozzle size
range from 0.10 to 0.35 mm
Siphon Feed - The advantage of this
style airbrush is the ability to use many different size color cups and bottles
and to change colors quickly. Nozzle sizes range from 0.1 to
0.5mm
Side Feed- The advantage of this style airbrush is the
color cup attacked to the side will rotate 360 degrees giving you the ability
to work at just about and angle or even over head. Nozzle sizes range from 0.10
to 0.35mm
