Review on Tornado 20-Inch High Velocity Industrial Wall Fan - 4750 CFM - 3 Speed - 6 FT Cord - Industrial, Commercial, Residential Use - UL Safety Listed by Michelle Ortiz

I bought this fan to cool my garage/workshop when I work there and this fan does the job well. I attached it to the ceiling. The included mounting bracket allows the fan to be rotated in elevation and I attached it to the ceiling joist with a mounting screw and wide washers (not included) so I could rotate it in azimuth/direction. That was sufficient, but I would have liked a slightly wider mounting bracket to make the single-bolt mount more stable. I suspect the manufacturer's intent was to secure the fan with more than one screw, but the instructions only talked about how to assemble it, not how to install it. During operation, the fan is relatively quiet considering the volume and speed of the air it moves. The cord is about 6 feet long so I had to pick a location with that in mind.
