in air handling unit
depends on if you have a 3 speed motor , if not its fixed on speed,

about 1000 cfm's per ton, and the indoor blower runs from 700 low speed 900 med speed and 1100 high speed. the red wire is low blue is med and black is high.
It should say on the compressor and the fan motor labels.
the aircondition fan is located in the outside unit of a central AC unit. It sucks outside cool air thru the fins and tubing that contains heat from air collected from inside the house thru the A-coil that's sitting on top of your heating unit. The inside fan in the heating unit blows air thru the cold air moving thru the fins and tubing in your A-coil and blows that air into your house. If you hold your hand above the outside unit while the fan is running you can feel the hot air that's coming from inside, this is how the heat is removed.
