The fan works by pulling air in and then making it move faster. The air flow behind the fan is slow moving and wide (you can see the arrows behind the fan coming from above and below the fan blades) whereas the air flow in front of the fan is fast moving and narrow (which follows from the conservation of mass flow.
How do you know the airflow of a fan?
The Rear or Exhaust side (the side that the air comes out of) of our fans will always be the side that houses the fan motor. You will also be able to identify the Exhaust side as you will see power wires entering the fan motor. Lastly, the fan airflow can be identified by the arrow markings on the fan housing.
