VEVOR 16 Inch Shutter Exhaust Fan Wall Mounted Automatic Louvers Silver, Sturdy Steel Housing, 2438 CFM Low Noise, AC Motor, Ventilation and Cooling for Attic, Garage, Barn, Greenhouse, Workshop

Installed it in our greenhouse. I have a min-max thermometer in there too. On a 90 degree day, the temp topped out at 115 degrees. When I walked in and looked, the temp was down to around 100 degrees. The thermostat is set to kick on at 105 degrees. The tomatoes love it. There is an automatic vent door, but with no wind, no air flow. The fan moves plenty of air to keep temps under control. Last year, plants died because temps were too high. Just like in a closed car, probably 150 degrees plus. Not any more. Quality made, not cheap at all. Note: fan does NOT have a thermostat, you have to supply one for it. The one photo showing the fan running was right after I installed it, and it was after dark. The yellow wire was a jumper to kick on the fan. In the 10 days or so after taking these photos, it's been working flawlessly. You have to walk into the greenhouse to hear it running, it's very quiet.

Made a notable difference in attic heat

Works well. I installed a variable speed switch which gives me more flexibility

Nice fan. Appears to be well made. Quiet and smooth operating. Shutters function well, completely opening when fan is on and completely closing when it's off. I cut an extension cord to make the pigtail but it would be nice if it came with a plug already or at least a longer cord. I hooked mine up to a thermostatic switch for venting my garage so it works automatically. We'll see how long it lasts...

Very good for my hangout shed when I'm not in there running the AC the size is good, and installation was easy wish it just came with a cable attached but I had a cable end lying around to get it to work also it keeps ac and heat in well when not on and it's not to loud on the inside and out it's a nice humm

Nice fan. The louver helps keep birds and squirrels out of my attic and prevents rain from entering. I paired it with a fan controller with a thermostat so that it turns itself on when the temperature gets too high. It does not come with an electric cord so if you want to plug it in like a regular appliance you will need to purchase/attach one. It also has attachments points that allow you to bolt it in place to a window, cutout, or other objects. I wanted this to mount in a window and be removable so I attached it to a frame I built to nest inside the window.

moves a lot of air easy install

Purchased this to help cool a small workshop in the garage attic. Its a barn roof style building and not insulated metal roof so gets very hot in the summer. This does a fairly good job of moving air, especially if I open the door on the other side. The price was the best for its size I could find This would be perfect if: - It always closed fully when off - It came with a power cord attached - The corners were sealed - no plastic on it I ended up adding a power cord to plug it in to a switched outlet. Its designed to be hard wired, this isn't really bad, but would be nice if it had a cord but was set up to easily remove it for hard wire install. This didn't affect my rating. It would be nice if it closed fully, but the louvers can rub on one side or the other and not close fully when off. I just bang on the wall when turning it off and it closes the rest of the way. The corners are not sealed so I needed to use some caulking on them so rain hitting it wouldn't come inside There is a plastic film on it which is hard to remove. The metal is stamped so hard to remove the plastic without cutting yourself if not careful.

fits well runs quiet moves a lot of air.

NO TIENE FUERZA SUFICIENTE PUES APENAS LEVANTA LA PERSIANA. NO LO HE DEVUELTO PORQUE LO MONTE EN LA PARED QUE TUBE QUE AGUJEREAR, PARA QUE NO QUEDARA ESE HUECO 1/10 PUNTOS. MUY MAL PRODUCTO.

Segueix funcionant bé després de dos anys.

Très bon ventilateur , moteur silencieux , bonne extraction de l'air , idéal pour une serre , tourne plusieurs heures sans problèmes
