My business has a swamp cooler (evaporative), but none of the windows open so I have no way to vent air. There is a vent in the alcove (?) over my front door facing downward. The vent is about the size of a box fan. I have been thinking about putting one face down on top of the vent.

If this is not a good idea is there a better option? I have an outlet not too far from the area, but do not think that there is anywhere near to hard wire. I could run a wire out the vent for a solar panel, but the awning is north west facing.

Vent opening:

Box fan bearings are not typically designed to run in that orientation. It will probably run for a while before failing prematurely. Might make it a couple months or just a few weeks.

This is a much more robust fan and they come in various sizes to better fit your opening. They move a lot more air, and many styles come with a thermostat and speed controller. Sorry for the Amazon link, this is just the general style: https://a.co/d/bLeBCeD

And that one will be okay laying to push air down?

The bearings are much sturdier as the fan is bolted to the motor, and the motor is a generic one meant to be used in any orientation. I personally bought [this](iLIVING 20" Wall Mounted Shutter... https://www.amazon.com/dp/B0BVY8VCNZ) one for my house to cool it in the summer and at half power, every open window in the house has a stiff breeze.

Thanks. I will look into that, but at that price 2-3 box fans over the summer would be a better way to go.
