Review on Powerful and Reliable Air King 9020 1/6 HP Industrial Grade Wall Mount Fan - 20-Inch, Black by Donna Taflinger

This is a great fan for garage/shop. Yes, it's a bit noisy at high altitude, but what do you expect from an industrial-grade fan? I can feel the air still circulating around me about 25 feet away (at altitude). That's a good thing, because this summer it can get very hot and sticky in the south. Also read some vibration complaints. There are no problems here. It vibrates a bit at low revs, but you can't tell if it's installed properly (no rattling or anything). Can't comment on durability, but I have an 18" standalone fan from the same manufacturer that still works. 4 years later.
