28 x 50 x 12 Fan

[unpaulie]

Recently built a 28 x 50 x 12 pole barn with a liner ceiling. 1 foot overhang on all sides with vented soffit and ridge vent. Can I install a exhaust fan to keep humidity/temps down? I would like to install below the liner ceiling. Or are there better option?

Not what you want to hear but, air conditioning works best for heat/humidity control of a room.

Then, there are whole house ventilators like the one in the pic that mounts in the ceiling, along with many other types of ceiling mount exhaust that will pull the air out of the room and exhaust it up in to your vented attic. A whole house fan ***** major air running wide open, and will require some way to allow air in to the room though. They come with 3 speed or variable speed controls though, as one prefers. JMO
