AC Infinity AXIAL S1238D, Dual 120mm Muffin Fan with Speed Controller, UL-Certified for Doorway, Room to Room, Wood Stove, Fireplace, Circulation Projects

This fan is pretty amazing, I plugged this in and put it to max and it actually started sliding back from the strong air it generated. At max speed, the fan was still very quiet and at low speed it is barely audible. The frame around the fan is metal and strong. I will be using this to cool the garage an active vent, the speed control is a nice feature specially if you will be using indoor in an audio / video room. Great fans!UPDATE: Fans still working well, it really helps cool the garage down. I finally plugged in the kill-a-watt to see the usage of the 2 fans running.Low = 16 wattsMed = 27 wattsHigh = 41 wattsI have also connected this to a smart plug to schedule the fans to turn on in the afternoon, really impressed!

Mounted these on a portable propane heater and they work like a charm! Variable speed works very well. We use it in the living room to offset the electric central air running all the time. The propane heater puts out a lot of heat. Ceiling fan helps disperse the heat kind of so-so but these do much better. Low noise, but there is some noise. Even with the cost of propane this heater and the fans put a big dent in our electric bill and we were still very comfortable. My son will probably be doing this in his home for next winter

Using these as replacement gas fireplace blowers. They are a little louder then I would prefer but are moving air. One note: the power cord coming from the speed controller are a daisy chain and the power connectors do not lay flat on the fan body which I would have preferred due to the tight quarters I placed the fans. Well constructed Aluminum. Giving them 4 star due to louder than preferred at about 47dbs.

we use these as replacement fans for our blower motor for our fireplace. Worked wonderfully.

I wanted a fan to push the air from our pellet stove to circulate heat better than the internal stove fan does. Our pellet stove fan does not run on the lowest heat/pellet setting so these fans are great for circulating the hot air from the stove while running it on low saving us a substantial amount on pellet use and it truly made a huge difference keeping our home warm this winter. The only thing that I didn’t care for was that you couldn’t change the direction the fan plug faces on each fan, but it was more of an aesthetic issue which really didn’t matter to me. Love the dial for fan speed. The fan is fairly quiet on the lower speeds and gets louder when cranked on high which is to be expected. Again, not an issue for me. The fans do not rattle or tick like many fans do which drives me to distraction. I’m impressed by the amount of air these little fans move and I plan on buying a few more sets. There’s so many uses for them other than just heat resistance functionality.

These things are amazing. Got them for my fireplace and they don’t disappoint. Well made and surprisingly quiet

These little fans blow all the heat out and not up. Our fireplace stove is working more efficiently and safely. I heard a lot of cussing coming from the installer.

I purchased these to aid in pushing the hot air in our basement from out wood stove through the floor vents. I was skeptical that it would make much of a difference, but these little fans really pack a punch! We noticed a drastic improvement in the air being circulated. The best part was seeing a decrease in the electric bill with our electric heat not kicking on nearly as much! out of recommend
