                              - Air is drawn through the propeller from the leading
                                  edge of the blades.                                                                                                                                                                                                Intake Side
                              - The concave side of the blade cups the air and
                                  pushes it away from the prop                                                                                                                                                                                                                Airflow Direction

               NOTE 1: Airflow direction and rotation must be correct in order for
                                the fan to operate at 100% performance.


               NOTE 2: If the propeller rotates in the wrong direction, you will not
                                get any airflow at all in the proper direction.
