I want to boost the heat from porch pellet stove, about 8 feet into the house.** A: It is really hard to understand what it is you are wanting not knowing what you are working with. If you have heat ducts going into the house from this stove it would boost the heat very well into the house, but if you are just trying to capture the heat from the air, that will be a problem. **Q: How many amps does this fan draw?** A: I never checked the amps it draws, all I was concerned w/ it is 110 volts, and I needed a duct booster fan and it has been working for several winters. I run 3-8" ones and one 6" and one 12" on my wood furnace that is ia a small building outside and theses fans help the furnace blower push tha air into the house. **Q: is the 420 cfm free air** A: Yes I use it for a booster in my plenum for my wood burning furnace **Q: Is this 8 inch radious or 8 in diameter?** A: 8 inch diameter ## Customer Reviews ### ⭐⭐⭐ 3.0 out of 5 stars Too Loud *by T***S on Reviewed in the United States on December 15, 2011* This fan is waaay too loud. I am using it to blow air between my room with a woodstove to the rest of the house, it is mounted in the wall 15' off of the floor. When hardwired in to a switch and this thing is on full blast it shakes and rattles all over the place even though it is securely mounted. I ended up purchasing the "Duct Fan Speed Adjuster" for another $30 here on Amazon so I could control this thing. This is a relatively quiet fan up to about 60% of it's speed and then after that it just starts rattling and sounds like crap, I'm sure this would be way worse in the actual application for this product (in a duct). There is no way I would ever use this product without the fan speed adjuster but that's $30, this fan was/is $40 so you're into this at least $70 plus shipping and handling costs. I also thought that 420 CFM would be enough for my application, but I was wrong because I can only turn this fan up to about 1/2-3/4 power before my wife complains and my 2 year old runs off scared. ### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars Good, fairly quite fan *by C***R on Reviewed in the United States on February 13, 2013* I bought this to make a thermal downdraft fan for the karate dojo I go to. That is, to suck the hot air of the ceiling and push it down to the floor through flex-duct. It wasn't until after I received it that I read in the instructions that it is only to be mounted horizontally. My application is vertical so we'll have to see how long it lasts since I'm ignoring the Manufacturers recommendations. ;-) The pipe around the fan is of a decent thickness and the fan is mounted solidly within. I did have to add a cord to it but since I wired a thermal switch on it anyway this didn't bother me. The fan pushes air well and is fairly quite. But, since I'm mounting it in a warehouse type environment, the forced air heaters drown out any other fan noise anyway. ### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars Running 4 months non-stop *by M***E on Reviewed in the United States on February 1, 2012* I got this fan to transfer heat from our living room where our wood stove is to our back bedroom. I used about 20ft of 8" flex duct and put the fan in the middle of the run. The air flow has been great, you can really feel it transferring the heat.So far we've been running it for about 4 months pretty much non-stop without any problems.The noise level is as expected for a fan. With it being up in the attic we can hear a slight hum when it is on, but you have to be listening for it. Most of the noise is just from the air flow through the register.The only negative I can say is there is no built-in mounting options, so I just used used some metal strapping and screwed it to a rafter. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pl/products/57324781-diversitech-625-af8-ab8-air-booster](https://www.desertcart.pl/products/57324781-diversitech-625-af8-ab8-air-booster) --- *Product available on Desertcart Poland* *Store origin: PL* *Last updated: 2026-05-12*
