Some fans can be reversed by just reversing the polarity of the wires to the
motor. HOWEVER, if the blades are pitched for suction they do a poor job of
blowing and vice versa. Sometimes this can be fixed by reversing the motor
direction and flipping the blades over on the motor shaft but that may not be
possible. Check with the manufacture before trying to change the direction of
air flow. You could wind up with less than half of the rated cfm.
