Can Ventline Vanair Trailer Roof Vent Blow Either In or Out


Hi I am trying to install a roof vent/fan on my van and I only have a 10“ area next to my solar panels. Since I can’t find anything smaller than 14 inch standard opening fans, I was going to get to two ventline VP-543SP fans instead. My question is can I configure the fans to have one of them blow inword and the other to blow out? Thank you.

No the Ventline Vanair Trailer Roof Vent # VP-543SP cannot be configured to run in an opposite direction as intended. While you can use two of these vents they will run in the same direction but do efficiently move 100 cubic feet per minute.
