Airbrush Definitions

[Hospital_Rocket]

Would some one please explain the difference between

Single and double action

Internal and external mixing

And the application difference between bottom and gravity feed?

Thanx

Single action = trigger controls air-flow only
Double action = triigger controls air and paint flow

These are just like they sound,
Internal mix is where the air and paint are mixed inside the airbrush.
External mix is where the air and paint are mixed outside the airbrush

These two I can't explain. My guess would be something to do with overall design, ie. Single vs. Double combined with internal vs. external

gravity feed , the color cup is on top of the brush
bottom feed(or siphon feed) the container attaches below the brush.

the gravity feed airbrushes usually have a pretty small cup
the bottom feed allows for a larger container to be attached.
