FRESH SPEED 4-Inch Backdraft Damper Shutter Inline Spring Loaded for Dryer Duct

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!

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.

High quality… easy install.

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.

We live in a very rural, windy area. Husband installed a vent for the microwave fan above our stove to vent outside. Any kind of wind had the vent making so much noise throughout the day Abe night. We finally got fed up with it and purchased this... it was extremely easy for him to install and sealed great! We no longer hear the extremely loud, annoying flapping and it has stopped so much backdraft. The fan ventilation system is even quieter than it was before! We've had it installed for over a month now with some pretty nasty storms and seems durable!

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.

Wow, this is beat my expectations. Works perfectly. Fits snug inside the duct. And its small size made a compromising situation that was very room to with, super easy!

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-

Easy to install.

Très efficace, aide à prévenir l'air qui entre et s'installe facilement ...

Easy-to-use plugged right into the 3 way tee & duct silencer no tool or clamp Did use 1 clamp on hose end

We used this item for our stove range vent. It worked great and it opens and closes with ease. Very quiet when running, no outside noises.
