We have two on the end wall in my work area at the dealership. They do pull the heat out in the morning but after it gets hot I shut them down. Don't want them pulling more heat in. Around 11am, I turn on my swamp fan to cool off.

We use two 16" 3-speed fans in one greenhouse (14'x44') and a 48" in our big hoop house (30x96). They definitely pull a lot of air. The multiple speed feature is nice, on high the 16" fans are pretty loud. Sound like a remote control plane or something.

Got ours from this company. They've got great phone support for finding what size will be best for your application.

Sweet !!! I'll check them out. I figured they would work decent, just wanted some reassurance before cutting a hole in my building.

You may not have a lot of options, but look at where your makeup air will be pulled in from, when deciding where to install the fan.
I worked in a shop where the fans pulled the air from the big door facing an asphalt parking area.
After any rainfall, all it did was pull in steam from the blacktop for the next 2~3 hours.
The Heck of things was that the fans exhausted into a weedy area behind the building were all the coolest air was.

Just saying that a little forethought in fan placement would have made that shop a lot more bearable.
Instead of wiring all of the fans as one and mounted on the same single wall, having one single fan operable would have let us pull that blacktop warmed air into the shop on a moderately cool day and saved a bit of propane.
Welding curtains on a stand can be used to help steer airflow too.

I own a Drycleaners with 30hp worth of steam boiler heat in the building.

A 3hp 48" exhaust fan pulls heat out.

Louvers on a fan will greatly reduce the airflow. I would use something like storm shutters over the fan that can be swung out of the way of the airflow during use..
Draw your air into the building from the cooler side/ end of the building and exhaust out the warmer side.
Air is lazy, locate the fan as far away from open doors as possible so the air will draw thru the entire building before exiting thru the fan.
Openings closest to the fan will have the most flow in towards the fan.

We have two like this, only run in the mornings. Don't like pulling heat in after that.

The back wall would be ideal if the fan could pull air in, instead of pulling air out. The rear of my building faces the woods and the air there is always cooler. I'm not sure a fan pulling air in could override the amount of air a 12x10 door let's in. The front of my building faces the driveway. I'm just trying to create some air movement.

Eat lots of beans?! :p

I found out that once You get used to air flow while working You can't live without it afterwards.
I usually just boil in my own steam. :confused:

A squirrel cage blower with some ducting blowing in from the end opposite the exhaust fan
An evaporative cooler/swamp cooler blowing thru ducts that are dircted down at the work areas wash, stir the air then the exhaust pulls the air out. More exhaust out creates negative pressure allowing, pulling more air in which increases the felt moving air coming in thru the blower ducts.

Here in Georgia we have high heat and humidity. You can't lower the heat but having felt airflow/ breeze helps evaporation of sweat in a high humidity environment.
I have 1.2 million BTUs of steam coming into the machines combined with summer heat so i kinda know sweat.

Well, I got a 20" fan and got it mounted. It definitely pulls the air out, it's a little loud but not as loud as a floor fan. Definitely could've went bigger, just didn't want to spend the coin.
