Which ever way it blows air... 8-)
Actually, squirrel cage blowers work by "slinging" the air to the
outside. The vanes on the cage are curved on the inside and
"straight" out on the outside of the cage. Rotate the cage
so that the curved part "points" in the direction of rotation.
Picture it as the curved part scooping up the air and changing
it's direction so the centrifugal forces (yes, I know that
there really is no such thing) throws the air to the outside
(and out the vent)...
