## Description

FRESH SPEED 8-Inch Backdraft Damper Shutter, Galvanized Steel Duct Valve | aluminum blades, foam sealed, fits 8" AC, dryer, extractor, bath exhaust ducts, one-way valve, blocks backdraft - desertcart.com

## 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
- Warm Prompt: Please note the diameter of this backdraft damper is 3.9" and it can be fit in a 4" diameter pipe or hole easily. If you have any questions about our air vent cover, our professional customer service team is here to assist you

### ⭐⭐⭐⭐⭐ Solid spring shut 6” option
*by P***L on February 20, 2026*

This worked good for me . Durable metal not cheap the fit was perfect for 6” duct. Proper airflow through it and shut as it should.

### ⭐⭐⭐⭐⭐ Easy install. Works great
*by R***R on November 26, 2023*

Well built. not perfect but 95% all you could ask for. Fits 6" duct nicely. Easy to install.

### ⭐⭐⭐⭐ Works as intended.
*by M***K on February 16, 2026*

Works as intended with solid backdraft closure. Care should be taken when trying to crimp the metal for inserting into a 4 inch duct as to not getting the damper out of round or striking the butterfly flap inside.
