The Windchaser fan captioned above is for crap!It is NOT Industrial!It does not meet industrial standards to be called "Industrial"!The item was to have aluminum blades. Mine arrived with plastic!What kind of false advertising are you guys trying to pull?
This seems like a quality fan. It moves a great deal of air, but is quite loud. If noise is an issue, I would look for a different fan. As stated in the earlier review, the blades are plastic not aluminum.It was easy to assemble, and the instructions are well written.
Nice fan, better than any I found locally. Easy to put together, good airflow. The description is flawed though. It says aluminum blades but they are plastic.
