My shop is un insulated and in direct sun anything over 70 degrees it becomes an oven. Was looking for some big fans but I'm doing a commercial restaurant up fit and they are doing away with alot of the exhaust vents. And well free is for me. Originally I was going to build a box with wheels and install this and have it force air to one small area. After looking at it more indepth I'm thinking about hanging this one and two others on the back wall and letting it rip. Which would be the better option. My neighbors will only smell Chinese for a while I would guess.

My shop roof is uninsulated with aluminum siding and its def an oven. I have a big exhaust fan at one end in the eve and then many other portable fans to move air. It's still hot as hell but I do have air moving
 
My shop roof is insulated and it's in the shade for the entire afternoon but it's still too hot. I need to insulate the walls and put a couple mini splits in. But time and money sure do fight these ideals. Anyway, I digress. Hang them puppies on the wall and rock on. Bound to be better than nothing. In my experience, wall mounted exhaust fans just don't evaporate sweat as well as direct wind blowing on me from a fan. But I also sweat like a cold metal roof on a humid summer day.
 
I have a HF cage fan at the top peak of my building on one side blowing out. 2 Ceiling fans sucking up, and a small fan one the other side in a doorway. I am in shade after 1 or 2:00 o'clock. it's "tolerable" un-Insulated steel building. I can pretty much keep the inside the same temp as the outside.

I'm trying to get some cross ventilation. I can open the front and pull air across and I'm still looking for a swamp cooler. Possibly try to turn one of these into one now that I think about it

Mount fan in sidewall position as high as possible on back wall. Crack garage door for best results (smaller the gap the higher the velocity the air travels). Pull in low on one end, exhaust high on the other end.

Exactly. My shop has a high rear corner fan rated to move the volume three times per hour. I crack the opposite door about 6 inches. That 14 foot by 6 inch crack creates a nice cross flow up and out. Smoke gets gone and a little trapped high heat as well. My only mistake was buying single layer metal roll up doors. They are a frying pan.


Absolutely skip the swamp cooler. Complete waste of money in our climate zone. We have to much humidity to get the evaporative cooling effect . Our average dew point doesn't make them work as designed at all. If you want stanky wet air the same temp as it's surroundings by all means get one. You would have to keep well water on a constant flush to get any cooling. With that your still increasing the humidity by a big factor. You feel more relief with an equivalent dehumidifier with the exhaust directed outside.
I run a small dehumidifier to deal with tool rust. It actually feels much better when I first walk in most summer days with just that going. Needing to get smoke out ruins it, but initially it's very nice.

I did some flexible welding hoods (exhaust you can locate right over your work area) for FTCC that were pretty neat. But those were for isolated work spaces of about 12'x12' and several $thousand 🤦‍♂️ but man... That'd serve you well
 
In my shop (25 x 70 rectangular with 12' garage door and 3' man door opposite end) I run a stand up fan at the man door and crack the garage door. It sucks the hot air right out with nice velocity.
If it were MY shop, not a rental, I'd place a fan up high like others said and get better cross flow.
