Can an electric fan be installed as a pusher or as a puller?

Yes, while all Perma-Cool electric fans are pre-assembled at the factory, and shipped as pullers, they are reversible. In most cases, to convert a fan's directional flow from a puller to a pusher, the blade must be removed and flipped over (or reversed), and the wiring must also be reversed. In some instances a fan can be converted by simply reversing the wiring polarity.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
