Purchased this fan for a 18x20 sunroom. This fan is for LOOKS only!! On the website it claims the CFM’s are close to 6000. The box arrived very tattered and beaten up. First thing I noticed was the CFM’s on the box said just around 2000. I called customer service. I explained that if this fan didn’t put off adequate air, I would like to return it. Especially because this is a very intricate fan to assemble. Well, 5 hours of labor assembling this thing! It blows air to the walls. It does not blow air down. We are devastated!!! We will be returning :(
