iPower12-Inch Square Aluminum Automatic Gravity Shutter Louver Vent, Silver

The vent works as it should. Light weight so louvers could easily dent if mishandled. No problems with install. Opens and closes smoothly when auto attic fan kicks on. Quiet too. Functions well. Cannot speak to durability but so far I'm happy with purchase. Super cool to watch the vent open when auto fan turns on. Hoping that the exhaust set up we created pulls all the hot air from the attic and cools the house for the coming Florida Summer. We bought the Quiet Cool Green, this vent matched it perfectly. Hoping to save a few bucks on the power bill. If stats are correct the investment would have paid for itself in the 1st year!

a fantastic addition to my attic ventilation system, especially paired with the attic fan I recently installed. This vent works perfectly by allowing fresh air to be pulled in whenever the attic fan is running, ensuring the space stays well-ventilated and cool.What I love most about this louver vent is its automatic functionality—the shutters open smoothly when the fan is on, and they close just as efficiently when the fan is off. It requires no manual adjustments, which is super convenient. The aluminum construction feels durable and well-made, ensuring it will withstand various weather conditions without rusting or wearing out.The installation was straightforward, and it fits seamlessly into the attic setup. Once the vent was in place, I immediately noticed a significant improvement in airflow, allowing the fan to work more effectively. The vent not only helps pull in cooler air but also assists in keeping the attic from becoming overly hot and stuffy.Overall, this gravity shutter louver vent is a perfect complement to any attic fan system. It enhances air circulation and helps maintain a balanced temperature in the attic. Highly recommended for anyone looking to improve their attic ventilation!

The embedded female nuts are M6-1.0 screw type... in case anyone is interested: had to figure it out by trial and error... using it for a shed and did not want kids hands going in with curiosity and encounter a metal fan blade... would be nice to have an option of a shield to crew on since a adapted a fan and not used one that directly attached to it

I received myiPower 12-Inch Square Aluminum Automatic Gravity Shutter Louver Vent, Silver.💁🏻‍♀️Very simple to apply on your outdoor kitchen vent wall, I’m a female & did it myself.👍🏻Packed & Shipped with care. It works amazing. No more cold 🥶 or debris interning my kitchen stove. Works as described. Love it.

Purchased to replace a plastic louver (that broke) for my gable end attic fan. I wish that I had bought this in the first place. It wasn't an exact match to the plastic one, so it required some installation modifications, but it has worked flawlessly. It's pretty quiet when the fan isn't operating, except when experiencing extremely high winds, which is understandable. Great product.

We love these fans. There was a definite improvement in our electric consumption, which is huge here in Florida. They are inaudible in the living areas and the garage and it is a one story house. Our undersized AC was able to maintain set point inside our home for the first time all summer long, and this was the hottest summer in history here. Worth it!

Was the same size as measurements on description . Good quality not thin . Perfect fit for me

Easy install and has been running very well!
