Questions & Answers

Is there a wildlife grille or can one be added?

Is there a wildlife grille or can one be added?
Asked by: TH
This fan does not come with one. You can probably add one from the inside or perhaps box one in from the outside but it will reduce the efficiency of your fan

Do the louvers operate independently or are they joined with some kind of metal wire device?

Do the louvers operate independently or are they joined with some kind of metal wire device? I'd be using these in an unconventional way, on a porch, is why I ask. I'd love it if the louvers were rigged to all work together so I could manually open and close the vents.
Asked by: Studiopop
I think the force of the air generated by the fan blows and holds them open while its on. Then gravity shuts them when it stops.The bottom of the flaps are weighted so they go back to the closed position when no air is blowing on them.

16.75 in. x 16.75 in. Aluminum Automatic Gable Square Mount Louvered Shutter Attic Vent is rated 4.2 out of 5 by 48.
Rated 4 out of 5 by from Good product! Product is good and would recommend it. You'll have to caulk the corners but that's no big deal (few gaps). Be-careful when handling due to it can be bent. I bent mine while screwing it to fan shroud but it was easy to re-straighten back out. I used mine for a solar attic vent. The fan I bought had a 20 watt solar panel which is not really strong enough to push the louvers completely open so I would recommend using a 40 to 60 watt solar panel. I went ahead and bought a 60 watt solar panel and it blows the lovers wide open! When using a solar fan, you have to keep in mind part of the pressure from the fan has to have enough force to push open the louvers and this will cause the fan to run a bit slower so that is why I recommend the larger wattage for solar use. If you are handy, you can buy a car radiator fan for $50.00 from online auto store, then buy a 60 watt monocrystalline solar panel for $105.00 at amazon. Find a remote controller from attic breeze or some other place and you're all set! Why spend $$$ when you can do it yourself!

Rated 3 out of 5 by from Good product. Works well. But, not perfect Product works well and is easy to install. Louvers are light weight, so the air from my attic fan easily opens them. They also close quietly, again because they are light. All is aluminum, so they won't rust. My biggest problem was that the aluminum frame did not meet soundly in the mitered corners. There was a gap on each corner that would allow water to infiltrate if the vent is mounted so it is exposed to wind and rain. I used angle aluminum screwed on the outside of each corner to narrow the gap, then caulking to seal them. In the end it seems fine, but did require extra, unexpected effort.
