How to Install Trailer Vent Fan to Run In Reverse

Question:

Would it be possible to run it reverse i.e. blow air into the van rather than vent it outside by switching the polarity or by putting in the fan blades the other way?

It is indeed possible, you'd just reverse the polarity of the wiring connections. I've confirmed this with my contact at Ventline.
