I needed a damper to keep cold air from making its way down my range vent and into my kitchen. I installed this damper vertically, in my attic, without any issues.The first image shows how much the flaps open after I connected the damper to my range vent and turned on the lowest fan setting. Not too shabby considering that the product I received actually had two sets of dampers, offset from each other on the inside (see first image and compare it to the image shown for the product listing). Because of this, I could only give 4 stars. Maybe two sets of dampers is better than one, maybe it's worse, I don't know. I'm not a damper expert. But aside from my product not matching the one shown, this thing seems to be performing as intended, quality is good, and the cold backdrafts have stopped. Note: I am using an Arietta Model # DKI001MX36 range hood, and according to their specs, the blower performance is 160 CFM (1.5 Sones?) on speed 1. Maybe this info could be helpful if you're wondering how much air is required to open the damper (or dampers in my case). ### ⭐⭐⭐ 3.0 out of 5 stars OK damper *by P***R on Reviewed in the United States πŸ‡ΊπŸ‡Έ on January 29, 2013* First thing about this damper is that it is bigger than it needs to be, if you are trying to fit this in a tight spot then I'd recommend going with an Air King. In fact, I have both speedi 6" and air king 8" dampers and the air king damper is superior in every way.(1) The dampers spring is very weak. This thing absolutely must be installed in the vertical position, which is not unusual, but it can be a PITA if your planned HVAC run does not have a vertical component in it mostly because this damper is rather large and you'll need 2 elbows to get it back in the horizontal position. In my case that meaned replanning the run a little.(2) The seal is foam, not even rubber, and it's sure to wear out sooner rather than later as a result of that,Overall this unit is about as poor as it could be and not have me send it back. I'm not happy with this damper, but it'll work in a pinch. ### ⭐⭐⭐ 3.0 out of 5 stars Kind of meh, but probably would suffice. *by S***N on Reviewed in the United States πŸ‡ΊπŸ‡Έ on December 2, 2015* Well it's a backdraft preventer and it looks like it will work but I have my reservations about it holding up. It doesn't completely seal right there are pathways, albeit narrow ones, for air to leak backwards even when shut.I purchased it for an unorthodox use but the concept is not out of realm of uses for this in my opinion. I had planned on using it as part of a crawl space exhaust ventilation system. I was hoping its default position in the horizontal application would be closed but there is no spring and even the slightest tilt causes the flaps stay open. So my hope was this... even that slightest winter air would stay out of my crawl but I don't trust it. It is hard to tell what sort of CFM would be required to close it to prevent backdraft. --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.ie/products/8766769-speedi-products-ac-bd-06-6-inch-diameter-galvanized-back](https://www.desertcart.ie/products/8766769-speedi-products-ac-bd-06-6-inch-diameter-galvanized-back) --- *Product available on Desertcart Ireland* *Store origin: IE* *Last updated: 2026-05-27*
