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

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.
