FWIW: I recently installed 3 Westinghouse 7861400 Industrial 56-Inch Three-Blade Ceiling Fans in my new 1800 sq. ft. shop (30' x 60').
They are non-reversible, but when its hot I keep the doors closed, windows open, and fans on high and it is very nice, warm, but not over-bearable hot. On high you get a definite breeze and they are very quiet.
This winter I'm running them on the lowest speed with the heat on and they work great to move the air up above down below.
My peak ceiling is 16'-4".
I am very happy with these fans.
