I've had a few Mathes Cooler's - used one as a renovation vent for a long time. Identical to the one pictured with the variable speed control. The finish was toast so I didn't mind using it as a vent before it met it's maker.
A good friend told me these were originally used as swamp coolers with wet media pads on the back side, thus that is what the brackets were for on the intake side. Draw air through the wet media to create a cooling affect.
The only issue? They would never work in the humid Midwest, but would work wonders out in the dry west. However they do make fantastic fans and move quite aa lot of air, and are fairly quiet.
Port-A-Cool makes large industrial sized ones today. You'll see them used by the NFL and College football teams this fall.
