## Overview

The 6" Draft Blocker Back Draft Damper is a robust inline duct accessory crafted from galvanized steel, aluminum, and stainless steel components. Designed for easy push-in installation, it ensures one-way airflow by preventing backdrafts in ventilation systems. Ideal for a wide range of HVAC applications including AC units, exhaust fans, and heating ducts, this damper enhances air quality and energy efficiency in both residential and commercial environments.

## Description

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. Back draft valve can be inserted into flexible or non-flexible ventilation ducts. Cannot be used with plastic ducts due to differences in size. 【WIDE APPLICATION】This backdraft damper is widely used in AC, exhaust fans, extractors, range hoods, heating ducts, vents, and other residential, commercial and industrial applications.

Review: works great for my microwave vent
Review: I have allergies and apparently if I leave my portable Danby AC connected to the Window I wake up wheezing with Asthma or rather a type of bronchitis that fills my lungs with mucus from the allergies. Coughing and wheezing throughout the night. I had no idea that a backdraft damper existed or at least I could imagine that it existed but I had to search for "AC Duct air Blocker" to find that what I was looking for was a backdraft blocker. Measured twice the size of my Duct and it turns out that there are only three sizes 4", 6" and 8". My duct was 6.5". When my Draft Blocker arrived and I fitted it into the duct it was loosely fitted so I added a foam seal around the draft blocker and that made the backdraft blocker a tighter fit. Wasn't sure how far to push it into the duct but on the first try I decided to just have it near the entrance of the duct and that should be good enough. Checked that it was closed when my AC is not on and checked that I had Air flow when I turned on my AC by checking outside whether there was hot air blowing out of the exhaust. Yup works wonderfully. SOOOO theoretically without the outside air flowing through my AC duct I should have a good sleep tonight. I love how that if I have a problem such as a Backdraft on my AC Duct that I could find it on desertcart.
