## Features

- Home Improvement: Perfect for use in AC, dryer vent, heating ducts, extractor or range hoods. Especially suitable for using with exhaust fan, bathroom fan, blower fan, attic fan
- 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 4-inch duct best installed in a horizontal position and inserted fully into the duct. This also applies to vertical installation
- Premium Material: The casing of the shutter is made of galvanized steel sheet. The dryer vent valve blades are made of aluminium. The shaft and spring are made of stainless steel. The shutter is able to withstand temperatures up to 140°F
- Great for Home Use: The foam sealing on the damper reduces operation noise and provides extra air tightness. The back draught valve can be inserted into a non-flexible metal or plastic duct directly, but for flexible duct you need to use steel duct clamps to secure the backdraft damper

### ⭐⭐⭐⭐⭐ Product is as described

Good damper with foam seal.

### ⭐⭐⭐⭐ Solved back flow and noise problems
*by M***1 on June 6, 2024*

We have three fans in our master bath, which created an air circuit pulling either cold or muggy air into the house. Installing one of these in each duct has stopped that completely, stabilizing the temperature and humidity in the room (meaning our HVAC runs less often to compensate). As an added bonus, we didn't realize how much outside noise we could hear through those fans, but it's sure quiet now. The foam ring effectively silences the closing of the butterfly doors, so there's no closing noise when the fan turns off. Only nuisance issue is that the hinge pin sticks out enough on both ends that you can't insert this into the tapered collar end of a duct, nor can the tapered end quite fit into the ends of this fitting, so you have to cut completely through the duct to insert it. This issue is the only reason I don't give it five stars all the way around.
