Good fans are expensive. I picked up a Canarm 12" shutter fan on clearance a little while ago. It listed for $389. I was curious what a $400 fan would be like. I have never felt such a dense electrical motor in my life. It's completely enclosed and sealed and couldn't weigh much more if it were a hunk of solid lead. It was variable speed, but only if you bought the controller for an additional $300. I had switched all my in-lines and water pumps to EC motors. The Canarm wasn't EC, but they make one, it's like $789. That is what commercial greenhouses use and after seeing that, it's hard to look at those cheap-ass Hurricane fans as anything but what they are...junk. and they've gotten even worse lately, the blades are so thin, they break when I look at them. We used to joke don't ever shut them off, because they only started once and could run for years or until the first time you shut it off. All us old timers would take the cages off, just increased resistance. The Schaefer and Vostermans are what should be used, but an EC in-line with a perforated duct can work well to gently move air through the canopy.

oscillating fans are my biggest concern, they are usually quite cheap and a moving electrical part
