## Description

2PCS 4'' Draft Blocker, Backdraft Damper Duct, Draft Stopper, Backflow Preventer, Inline Fan Vent DeflectorFeatures:  What Is a Backdraft Damper? A backdraft damper, also known as a gravity damper, is a piece of equipment that allows air to flow through in one direction while preventing air from entering the opposite side, also known as a backdraft. Backdraft dampers assist in the exhaust or intake of heating, ventilation, and air conditioning (HVAC) systems. Why Do I Need a Backdraft Damper? A backdraft damper is beneficial if you are looking to control and enhance the air quality of your home or office. Installing a damper keeps temperature-controlled or purified air within your space while simultaneously keeping outside air from coming in. A backdraft damper is useful in controlling temperature but can also be used to improve the ventilation of a space.  Ideal for all tumble dryer vent pipes / hoses, bathroom extractors and vents, air conditioning and heating units, kitchen vents and fans, all home wall and ceiling vents, heat transfer and ventilation systems, gas and electric dryers, cooker hood extractors, as well as a wide variety of industrial uses.Specifications:  Quantity: 2 PCS Material: Quality galvanized steel Color: Silver Mold size: backdraft damper: 100x88x0.5mm/ 4x3.5x0.02inchesPackage contents:  2 x Backdraft damper Warm Notice:  Please consult and pay attention to product size before buying.

### ⭐⭐⭐⭐⭐ Worked great
*by B***B on January 17, 2025*

These worked great. The gasket keeps any flow from backdraft Just note that they only fit over female end.

### ⭐⭐⭐⭐ They seem to work just fine
*by R***. on February 2, 2024*

I elected to vent two bathroom exhaust fans through a single roof vent. I installed these backdraft dampers to ensure exhaust from each bathroom traveled out the roof vent and didn't travel into the other bathroom. These dampers appear to meet my objective. I didn't venture onto the roof to see how much air volume is exiting the roof vent, but I ran each fan individually and checked the non-running fan opening for an signs of air movement from the fan into the room and didn't detect any. You need to install these dampers in a horizontal position and that took a few minutes to get right in my situation. Other than that , they installed easily with some clamps and foil tape.
