Hello I am looking for a inline two to four inch duct fan (booster) that can blow forward or reverse. Just trying to move air around my house forward for winter reverse in summer. My house is odd shaped with a 16/32 22ft ceiling addition in the back. Anyone know of one? Thanks

As far as I know, no such thing made. They're all made for one direction.

you could just use two of them. A three position switch could be set up for Summer/off/Winter.Some chillers use reversible fans for low ambient. Problem is going to be they move air great in one direction, not much in the other.
