Product Description
These automatic roof ventilators have been designed to help reduce the amount of energy needed to cool your home by as much as 40%. That's because they're designed to help ventilate your home without having to open windows or turn on the air conditioning. And they do this by automatically operating when the temperature rises to 75 degrees or more. You'll be able to tell that it's working because you'll see the powerful, efficient and virtually silent motor spinning. And it's also very easy to install. All you need is a ladder and about an hour of time. And you'll be able to keep the fresh air flowing throughout your home all summer long.
