 Airbrushes

 The SINGLE ACTION airbrush has a trigger that controls the airflow only. A pre-set amount of liquid is sprayed when the trigger is depressed. You can only adjust the amount of fluid released by turning the liquid cap on the paint tip located at the front of the airbrush.

 The DUAL ACTION airbrush has a trigger which controls both air and color by pressing down for air and back for color. This trigger allows the artist to change the range of opacity and the width of the line easily, without stopping the spraying motion.

 INTERNAL MIX means the air and paint mix inside the airbrush. Air and paint come together inside the head assembly to produce a thoroughly atomized fine point spray pattern.

 EXTERNAL MIX means the air and paint mix outside the airbrush. Air and paint come together outside the head, or fluid assembly. External mix airbrushes produce a larger point spray pattern than internal mix airbrushes.

 The GRAVITY FEED AIRBRUSH is the choice of professionals for fine art in almost every Airbrushing operation. The Gravity feed requires much less air pressure to operate, as the paint is supplied to the air mix chamber by gravity, thus eliminating the high air pressures required to siphon up the paint materials from paint jars siphon feed units use. The finest of lines are acquired from an airbrush by using  the lowest possible air pressure settings, thus  making gravity feeds much superior for fine detail. This also makes the airbrush easier to clean, and you well have much less clogging problems. Most fine Gravity Feeds are Dual Action, Internal Mix.
