My shop is 50'x75' and 12' high down the center.
I have a fan mounted in the wall up high at each end.
The fans are form old condensing units and move a lot of air.
This creates a good breeze thru the shop from north to south.
And,I usually use a small fan where I'm working.
Best I can do living right on the Ms. coast in all the humidity.
It's at 98 % right now!And,raining!
Mike.
