I live in a windy area, and the outside vent cover (plastic) opens in heavy wind, which allows the internal baffle to flap (loudly)--Any solutions?

I also live in a windy area. I have a "Broan Nutone 636 roof cap with flap". I have not had any problems so far. Have been through a couple of storms and it has been fine.

You will need a passive inlet model number FV-GKF32S1 this allows make up (supply) air to trickle into the home and helps to prevent excessive negative air pressure that can be caused by environmental or mechanical effects.

I am familiar with two vent flappers. One is in the Panasonic unit, the other is a "clothes dryer" type at the exit through the wall or roof. Both types depend on gravity to close them. Be sure both flappers are installed correctly for the gravity assist. My guess is the primary problem is the "outside" vent flapper. Try another type of "dryer " vent. If that doesn't work try a baffle around the vent to disturb the air flow. When we get the strong Santa Ana winds here in Southern California, I can hear the wind slightly when standing under the unit even though the vent pipe run is about 12 feet from the unit to the outside vent. I do not get any "blowback" in air through the unit, nor does the flap in the unit "flap" open and closed with the strong winds. If your flappers are installed properly to take advantage of gravity, then a baffle around the outside vent to disturb the airflow may be your best bet.

Easy to install well worth the purchase , and you will be happy for the vent cover !!!

Ironically, we have had very high winds with storms over the past two days. No problems with the cover what so ever.Works like a charm.

It gets fairly windy at my house and I've never had an issue. I keep the weber cover on it also if that helps.

I have not noticed wind noise at all, and am very happy with the way they fit and look. I am very glad that I purchased them. Also, I installed them myself!

This will fit all Fan-tastic vents pretty well. As for the wind - if you live in an area where the wind will damage the cover of your vent, you have bigger issues to worry about. The cover of the Fan-Tastic vent is pretty sturdy. This cover is designed to protect your vent from debris and water while allowing it to remain open for ventilation purposes.

More obstruction of the wind flow results in loss of effectiveness and higher noise level. I am wondering what can be expected from the unusually small apertures in this front grill.

my vent came assembled . the top is plastic and you need to mount it with the hing forward or or the wind will rip it rite off and also titen the handal snog but not too hard couse the wind will also lift it open

its a vent. stake it open and it provides ventilation, the "flap" acts as a rain hood

I believe the venting system can either be internal, where it sucks in the air but doesn't really go anywhere as it dissipates internally. Or you can flip the fan mechanism in the back center (take it out and turn it so the fan faces out), this way the vented air will blow through the microwave and back into a vent that goes outside, or it can simply be vented into the wall. Cut the drywall behind where the vent would go and the air blows in behind the drywall.The ideal is to have a vent that goes outside though.

Bibration noise is loud on winds over 15 mph. Not appropriate for roof mountin as noise travel. I just took my down and plan to sell it.

You're welcome and absolutely reduces the noise of wind rolling over the crossbars. I never heard the wind until I put the crossbars on my SUV, once I installed the fairing I couldn't hear the wind anymore.

There is a plastic piece inside that floats up and down with air pressure from the dryer to seal out outside air. If this vent closure is turned 90 degrees this vent closure will not work as designed.

There's an exhaust on one of the sides. You have to vacuum in favor of the exhaust side to keep the dirt swept up from blowing anywhere.

I can't find a way for the tape to wind. We leave the cover off and manually wind it as needed.

If you don't have any way to vent outside like windows or something, you might be able to build a water filter to clear the exhaust. It wouldn't be too hard and would only require some engineering and pvc.
