Ceiling Fan on Corrugated Steel Ceiling

[GAR64]

I'm thinking about installing a large ceiling fan in my garage to help keep humidity down. My ceiling is corrugated steel (like roofing steel). The building is 36 x 30. I have not picked out the fan but was thinking about a 6'. (Yes, those Big *** fans are nice but too much $). Based on the weight of any fan, I know attachment is important. How are people attaching on a ribbed ceiling? Trusses are 2' OC. Any recommendations on a particular fan also appreciated.

You need to bridge the trusses. No recommendation on a fan but shop fans are common in all shapes and sizes. They seem to cost more than residential fans which do the job.

How is a ceiling fan going to lower humidity?

I do use a dehumidifier but want to add some airflow.

Warning: Physics lesson.

The ceiling fan does not actually reduce humidity, but it does even out the areas of the room with humid air.

Water droplets collect on your cold drill press, and thus the air around the drill press is more humid than the rest of the room. The humid air around the drill press cannot hold more water, so the fan moves the humid air from around the drill press and replaces the area around the drill press with less humid air that can now absorb more water.

This will help keep your drill press from getting surface rust, but you still need a dehumidifier to actually remove the water from the air.

This is the same way a fan removes sweat from our body. If you stand in still air, the area around your body becomes saturated and cannot hold more water. The fan blows away the wet air and replaces it with dryer air.

Weight hangs from the trusses. Gotta make that happen.

Lowes has a giant fan. Not big *** but consumer equivalent.

Had mine for 5 years. Works ok. Sometimes turns on or off spontaneously. But no bid deal.

Looks like they have a 96” as well.

Bluedog, yup that is the one I was looking at. The 72". I see that do have good brackets for 2' space that you can install from below, since I don't have access above. Barnabas, I appreciate the Physics lesson.. I get it. I should have clarified by saying I wanted to reduce the issues caused by humidity by adding airflow.

I had the same situation...solved it with a Home Depot 60" 3 blade garage fan (actually 2 of them for my 30 foot building).
It comes with a 4 speed controller that mounts on the wall.
cost was $49 about 10 years ago, probably $69 now, but it works really well for my purposes.
I have not shut it off since I installed it...it runs 24/7 with no problem.

There are some really neat expandable mounts that work w/ wood joists. I have used one a couple of times w/ great success.

The second one is the style I have used. What is your corrugated steel hanging from? Wood or metal?
For the fan itself, I would just buy a standard home unit. Our bedroom and living room fans go on sometime in April and off sometime in September and we have never worn one out.
