Features
- Home Improvement: Especially suitable for inserting into dryer duct. Perfect for use in bathrooms, garages, sheds, campers, stopping inflow of air from AC units, range hood extractors, heating systems
- Easy Installation: The duct damper opens and closes automatically, allowing only one-directional airflow. The damper blades open only in the outflowing air direction when the shutter is installed. The duct valve for 8-inch duct best installed in a horizontal position and inserted fully into the duct. This also applies to vertical installation
- Great for Home Use: The inner rubber seal is used for better tightness and for noise reduction. The outer foam sealing strip provides good tightening and fixing of the backdraft damper inside the duct. The back draught valve can be inserted into a non-flexible metal or plastic duct directly, but for flexible duct you must use steel duct clamps to secure the backdraft damper

I installed this for my daughter on her dryer duct at an apartment. The duct had feedback so we put this on to ensure the airflow was one way only and not flowing back into her dryer. IT was a perfect fit with the flexible duct tubing and the dryer. I did not need to bend or crimp anything. The flapper doors work very well and it’s a quality metal product. Very easy to install. So far it seems very durable. Great value for the money!

My microwave vent to the outside of the house was letting cold air pour into my house. I purchased this backdraft damper and it instantly fixed my issue. It slid perfectly into place and has a good seal around the outer edges. The flaps do have small holes where they connect to the hinge but I put a piece of weather stripping on each side. It still lets the flaps perform like they should and when they close, it creates a perfect seal that blocks out any traces of air. Definitely recommend if you need a quick fix to stop backdraft and don’t want to tear all your duct work out.

I had a serious draft coming through my range hood. If you put your hand under the vent you could feel all the cold air seeping in. I purchase this backdraft damper and put it in the wall end of the duct in the image, and it was perfect. I no longer feel any air coming in. The spring mechanism works well as I see no difference in noise or airflow when I turn on the range hood. It seems to be well made and should last a while. Trapping out the cold is worth the cost. Especially these days.

This backdraft damper has been very effective at keeping odors out, which has made a huge difference. It works well most of the time and has really improved the air quality in my space. The only downside is that it occasionally gets stuck, so I have to check on it and adjust it now and then. Other than that minor issue, it’s a solid product that does what it’s supposed to do.

Perfect! We had a cold windy day and I felt cold air circulating out from under my range. It was pouring in from the microwave through the vent hood duct. My first winter in this home and found the vent on the outside doing nothing to prevent cold air blowing in through the microwave vent hood. This fit perfectly INSIDE the 6” duct and created a great seal to prevent any draft coming into the house through the duct. There was not room for an additional fitting as there is a 90 out of the wall into the hood. Good quality, perfect amount of spring tension, the vent van pressure opens the damper with no problem.

Excellent! Simple, fast, and easy to install, this product connects the laundry dryer exhaust to the outside. I had looked all over the retail marketplace before buying this through Amazon. A very well-made product at nominal cost! DJD-

SAVED MY WIFES SANITY AND OUR DRYER from being removed from our home. Wife was going crazy with the dryer having a musty wet smell after drying the clothes especially if they sat in the basket for any length of time post drying. Our dryer exhaust was installed in the slab at some ridiculous pathway to the exterior and didnt include a damper flap which after installing this one COMPLETELY SOLVED ALL DRYER RELATED ISSUES LIVING IN FLORIDA! The humidity here is on a level of insane that you may well just decide not to deal with. Ya beaches are cool but 65% humidity in the house was killin us! now sitting at a comfortable 48%-52% after damper installation. Damper fit inside of our 4" pipe and sealed using a little rubber/foam gasket. The flaps are spring loaded stainless steel and easily alert you to when they are working although the sound easily drowns out during dryer operation. one way dampers are the way to go!
