It isn't much in the way of Variable Speed. It starts fast when first turned on, but any significant change to regulate it slows it down, and it essentially operates at one slower speed when the dial is turned. This is fine for what mine is intended for and will not be an issue. My intended use is as an exhaust fan for an emergency generator enclosure during a power outage. The generator itself will be the power source, and it will only be run when needed, so I didn't need an outlandishly priced fan for this. The only issue I have with it is that bugs can enter from the outside through the louvres. We have a lot of undesirable insects that like to ruin electrical equipment when they get a chance, like mud dauber wasps or yellow jackets. The only solution to this problem is to block their entry, and a stainless-steel screen is what I wanted to use because it has stopped them for years now in simple vents installed. This is where the problem came up. The fan blades extend out into the exterior shroud enclosure that surrounds them. There is no room to allow a screen to be inserted between the shroud and the fan motor and blades without the blades hitting the screening. To me, this is manufacturing oversight for something like this, whether used in an attic, garage, shop, or generator enclosure, in my case. Perhaps they will read/see this and include it in their future builds. My only solution was to disassemble/remove the wire cage surrounding the blades, which also contains the motor that runs it, and raise it off the exterior louvred portion enough so that the blades would not touch the screen (pictures included here show the interim fix without the screen being trimmed after testing the feasibility of this). Basically, I put in a stacked set of nuts larger than the bolts that attach the fan cage to the exterior, but I also had to replace the short bolts with longer M4 bolts that would reach the threads of the exterior. I could have used a coupler, but there aren't a

the fan itself is very nice. Louvres work smoothly, and fan has good power. Was easy to mount. Took away a star because the control panel is very difficult to use. Instructions in the manual are crappy and unclear. The digital face is impossible to see when it's daylight (very bad for a greenhouse). We have resorted to just manually turning it off and on. Tried finding some you tube videos on setting it but unsuccessful so far.

I bought one, the remote didn’t work. Contacted customer support; they gave me a label and returned it and gave me new one and it worked fine. So remote was defective but they made it right, also be sure to push the cord in tightly.. I thought the second one was defective too but was just cord. Once we got it working; it’s a great product!! —ALSO, make sure not to pinch fan into a hole or louvers will not close all the way.

We bought this to use in our pig barn which is about 20x20. It has helped thus far to keep the dust and humidity out. The programming is a little complex, but it was very easy to install and does a good job. It has multiple options for programming and a timer as well.

I used the fan only to blow air around my wood stove. Work good with low noise level.

So far the fan is functioning as promised. Worth the price.

Programming the controls was difficult and hard to understand however, the exhaust fan works great.

Fácil instalación parece buen material se ve fuerte y potente, lo único que le falta es una maya protectora para no dejar entrar mosquitos, zancudos y moscas.

Pretty good unit, it does get the humidity out of the garage with the proper settings, however, make sure you lube the vents because they will not close all the way.

Works great. Easy to install. However, to me it seems like the power cord and controller are upside down. Not a deal breaker. Just an observation.
