VEVOR 12 Inch Shutter Exhaust Fan Wall Mounted 1347 CFM Automatic Louvers, Sturdy Steel Housing, Low Noise, AC Motor, Ventilation and Cooling for Attic, Garage, Barn, Greenhouse, Workshop, Silver

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

Works great!

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

Ottimo

facile da montare, buona ventilazione
