Aerovent AIRFLOW/ROTATION OVERVIEW
©2017
ADJUSTABLE PITCH PROPELLERS (AIRFLOW = MP) AIRFLOW = MP (AIR OVER MOTOR THEN PROP)
Rotation is determined by viewing the propeller
Airflow Direction from the discharge side of the fan.
Leading Edge of Blade
- Air is drawn through the propeller from the leading Intake Side
edge of the blades.
- The concave side of the blade cups the air and Airflow Direction
pushes it away from the prop air passes over Motor
then through Prop
(Airflow = MP)
aka: Hub on Discharge

LH Rotation
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.
