Your review: These fans are as advertised. Beefy, heavy duty, and will flat move some air. Our use is in a coin laundry of 2k square ft. We used two fans and the effect was super satisfactory.
1. The mounting brackets did not quite align with the fan causing some drilling and the purchase of a new bolt. Very heavy duty brackets.
2. One of the fans had a one piece of the wire screen bent. It could have happened en route. It was easy to bend back.
