Ceiling fan for shop

[cj7365]

I have a 30x50 metal bldg with 3 inch insulation, I am in the southwest and I am going to use a evap cooler to cool it in the summer, Just wondering if anyone has use ceiling fans in their shop, if so do you have pics.

It was 89 in the shop today

I suggest several! Best $ I ever spent in my garage was a window a/c unit. Only regret was not getting one w/heat too. Gets very hot here in the South, the garage a/c is running now...when I build my separate (not atached to my house) garage, I plan to hang several fans too.

I have 2 ceiling fans in the work bay of my 28' x 48' x 15' Pole Barn. Also put an exhaust fan in the back wall that I'll use during the night to pull in the cool night air and shut it off during the day and close up all the doors. Now that the barn is well insulated it will stay below 75º in there all day during the summer months if I keep the doors closed. The ceiling fans are more for the winters here in Michigan to move the heat off the ceilings. They are a little hard to see in the photo against the white metal ceiling.

I have one ceiling fan, use it both summer and winter. Always blowing down, FWIW. Also, in the summer, I can turn on the fan in my heater which generates a nice breeze inside as well...

THIS THREAD from 2007-2008 will be your best info.

I have pics of mine in a couple of different posts. I have a 60x60x16ft eave steel building with three 60" fans. I run them on high in warm weather, anytime I have the building opened up. They push the heat down, the wind carries it out the doors. Eliminates the broiler effect of having heat bearing down on your head.

Why push the hot air down to exit. Why not use a gable or roof vent to move the hot air out.

I opted to put a small whole house fan in my small garage to take the hot out of the top and bring the breeze from outside in. Because its a garage I do not have doors on Eric end thus no flow through of air.

Well, it works in my situation. I don't like the roof peak vents used on steel buildings, and installing a gable end fan would mean more cutting, hacking and issues with the install. I know a couple of steel buildings with the huge gable fans with the gravity closed shutters, and yes, they do work. The ceiling fans are invaluable in the winter to push the heat down, so you probably would want to install them anyhow.

Actually, after the fans have moved the superheated air from above, and it has "left the building" the air coming down is not really hot at all. Temps on the underside of the roof are only a degree or two more than at floor level. Never have any trouble working up high on the hijacker at all in the summer after I have run the fans for a while, but yes, you do need flow thru circulation. I have a 10x10 door on the north side, a 12w x 14h door on the west side, and a 53w x 14h door on the east side.
