I’m having some outlets added around the shop, and one of the things I’m adding is outlets for two wall-mounted fans. I have two ~10×10 bay doors on the front of the shop, a 6’x4’ window across from them, and another 6’x4’ window perpendicular to them. Shop is 30’-8” x 26’-5” with 18” ceilings.

My initial thought is to put them on the back wall, about 1/4 in from each side, with the assumption that with the windows and doors open the air will flow. I’m planning on putting them up about 1/3 of the way vertically. But I don’t know if there’s a better location.

IF you want the wall mounted fans to help with dust control, mount them: on opposite sides of one another, one close to the ceiling, one close to the floor, add furnace filters on both sides of each box fan. If you are looking to just move air, I would do the same thing except mounting both fans at the same height.

Box fans will move a lot of fine, airborne dust around your shop. For your health, put the furnace filters on them to help trap and minimize the airborne dust. MINE are on a timer to run for an hour or more after I’m done producing dust. I use 2 filters on the incoming air side, one is a hepa and the other is a standard filter. This setup allows the more expensive hepa filter to last a lot longer.

I’m looking just for cooling, not so much dust. I’m in SE Florida and the shop gets almost unusable during the summer. I have a large jobsite fan and a smaller oscillating fan now but I’m hoping to get something up that gets off the floor and moves more air.

Sounds like maybe something like this would be better?

Also, this is the fan I have in mind.

Up off the floor and moves more air, sounds like a good idea.

I’d locate the power outlets, for the fans, to be as flexible as possible. Airflow is complicated and there’s really no way to know what is going to work best for you and how you work. I’d plan to make use of the 12’ power cord the fans come with.

Given that, center a power outlet on each side. Or simple put a few on each side. Outlets are cheap.

In the end, I think what will give you the most comfort is going to be having the fans blowing at you to keep you cool.

Based on your drawing, with the fans in red, I would think turning one so that the two work together to rotate the air around the shop might be best. I do realize the fans have swivels and this is trivial.

Also, if part of your goal is to help move air through the shop, then you really want a fan “in” the wall of the shop drawing in fresh outside air. Moving air is helpful for comfort, but will do nothing to remove the heat. I wouldn’t want to rely on random breezes for what air moves through the shop.

I’d also get an AC unit, but that’s a different topic.

I’d like to get an AC unit but I don’t even have a table saw yet so that’s not high on the list of priorities.

What I was hoping these two fans would do, oriented more or less as they are if not rotated even further towards the bay door, is draw air in through the back window by pushing air out through the bay doors.

I’m thinking now that if I put an outlet in each back corner that would give me 12’ in either direction from each to mess with. I was hoping to “nail” the outlet location a little better though so as not to have cords dangling all over the place.

I’ve been considering getting some window fans but I haven’t seen one that allow me to close the window(s) which is an issue for me.

Maybe I just need to save myself some money and get a pair of these for that back window…

For my house, I made what my wife and I affectionately call the “ghetto” fan. We have a large house that is cooled with AC. It was frustrating to have it cooler outside than in during some evenings, but no way to draw in that outside air. So I mounted two box fans to a sheet of plywood that fits in the channels of a window. These fans exhaust and we just open windows as needed around the house.

Box fans are very cheapo and it is simple to mount them to a sheet of plywood. In your case I might attach the plywood to the wall just in front of the window and therefore allow the window to be closed without having to remove the fans. Lot’s of ways to skin that cat.
