Thank you Lonny. That is what I did. I flipped the blade and will run it in reverse polarity so it pushes air from the top down to the ground. Making it a "pusher" fan instead of a puller.On a fan, if you flip the blade over it does not move air in the other direction. It just makes the fan less efficient.
Fan blades have a leading edge and trailing edge. If you want to make a fan a pusher you will need to reverse the polarity and flip the fan blade so that the leading edge hits the air first.
