## Overview

The 8" Draft Blocker Back Draft Damper is a robust ventilation accessory crafted from galvanized steel, aluminum, and stainless steel components. Designed for easy push-in installation in 8-inch ducts, it features a spring-loaded flap that ensures one-way airflow, preventing unwanted backdrafts in HVAC, exhaust, and ventilation systems. Ideal for both residential and commercial use, it enhances air quality and system efficiency while maintaining a quiet, secure seal.

## Description

Back draft damper is made to insert into inch ventilation ducts. Backflow damper RKI automatically opens and closes. Strong spring loaded for horizontal or vertical mounting Flaps fit completely inside the duct making them suitable for aftermarket wear.

Review: It comes with a factory glued gasket and the gasket is what holds the flaps in the closed position, unfortunately the gasket wasnt glued properly and got displaced soon as exhaust was used, causing the flaps to not seal properly. It had one job and it failed at it, relying on a poorly glued gasket to limit the flaps os not a good idea. Need to install own gasket and or limit the travel of the flapa
Review: Works well, makes a tight seal, no tapping sound when the flaps close, a little undersized for 8 in hvac. But not so much that some hvac tape couldn't seal it. Easy to install. Seems like it will hold up for a long time. Decent damper for the price.

## Features

- 【Material】The 8" backdraft damper is made of galvanized steel and the flap leaf is made of aluminum and the shaft and spring are made of stainless steel
- Installation Method: The backdraft damper is installed by pushing it into the ventilation pipe. When installing the flap horizontally, make sure that the spring position is level so that it can be opened and closed for optimal opening. This also applies to vertical installation
- 【Function】This air flow control backdraft shutter is designed to fit TD lip and improve ventilation by preventing air from recirculating when the fan is not in use
- 【Widely Used】Backdraft damper is widely used in AC, exhaust fans, extractors, range hoods, heating ducts, vents, and other residential, commercial and industrial applications
- 【Note】Backdraft valve can be inserted into flexible or non-flexible ventilation ducts. Backdraft dampers are not for use on plastic ducts due to different sizes

## Questions & Answers

**Q: Can this be used to stop my Hot water tank from blowing out the flame on windy days?**
A: sorry, I did not use it for the flame from  HWT.

**Q: can this be used on a dryer vent or will the foam seal melt?**
A: I would say the dryer heat could damage or maybe even melt the seal. Maybe you could try removing the gasket and wrap a strip of fiberglass in it’s place.

**Q: Would this help keep out bugs?**
A: Yes it creates a barrier and only opens one way from the inside of house

**Q: Would this fit between two sections of standard, 4 inch semi-rigid ducting? Looking to add to bathroom vent fan ductwork.**
A: Yes, that's exactly how you would use it. Make sure to buy the correct HVAC aluminum (metallic) duct tape for the connection. A clamp cannot be used bc the crushing pressure would inhibit the flapper from working properly.
