As rated .. seems to be a good fan for the price and features, but it's nowhere close to the rated CFM. (4800 for the 20" model - or is that just the rating for the largest version?) In any case, I doubt it moves even 1000 CFM such that it was a waste of money. I need something that moves more CFM in the same space..

Installed the fan only to realize the temperature controller does not work. Can't return it because I've already installed. The only reason I bought this one was for the thermostat.

There's absolutely no way this fan moves almost 7000 ft.³ of air per minute. It's rated at 6900 and it doesn't even come close. I have a $50 floor fan that moves more air and that's not an exaggeration. The fan barely blows hard enough to keep the louvers open. I bought the 30 inch version and I'm very unhappy. I've already installed the fan so I'm not taking it down but I should've just spent the money and bought a real industrial attic fan.

Install was great, quality looks great, only problem is it has a loud resonant frequency. High speed or low speed, it is always there, same frequency and same loudness

Very noisy fan at low speed

I had a few issues with this product like the cord not being long enough the fan speed control looks like it has a lot of options but when you set it on anything close to 3/4 or more of its highest setting soon as you let go of the knob it moves itself back down to under 3/4 speed so unless it's only mine that does this there's no need for a knob with that many settings if 1/4 or more don't actually do anything

The fan sitting on the table does not even provide enough CFM to even open the shutters a 1/4 of the way. I have 8" fans that produces more CFM.

Not about the product but the poor customer service. I tried to return due to being too large for my windows and company insist i have to pay when i contacted them with 16 days for return. The ticket i submitted was acknowledged but NOONE finalized my request and when i finally got online to chat the agent was insisting on not helping and wanting me to pay for return of my product. I have never had a horrible return experience like this one but i have to warn customers, if you buy its yours! Buyer Beware.

Fan came with one louvre bent. The aluminum is very thin and was able to bend it back. With light wind the louvres flap open and close making it noisier than the Canarm fan opposite side of greenhouse. Same size fan but much much lower cfm than the Canarm which was twice the price. Really proves you get what you pay for! Very short electrical cable to make your connection.

While the service was prompt, when I put the fan in, took the tape off and started it for only a minute, the shutters became bent. I have asked for a refund or a fix. I will see how they respond
