AC Infinity RAXIAL S8, Inline Booster Fan 8” with Speed Controller

Rented out a house where I had to run heat to a bedroom and bathroom that the previous owner converted from a garage. Ran duct instead of the baseboard heater that was previously installed. It was a pretty long run, about 35' of 8" ducting and a couple branching off of that. 4 total registers. Went to the orange store to buy one of these but they didn't have the 8" in stock. Said I'd have to order it online and when It comes to that, I'd rather just order it on Amazon. This thing is solid. Metal fan blade, pretty solid housing. And cheaper than the store by about $20. Probably got it faster than if I'd ordered from the store too. The housing is a little smaller than a normal metal pipe but it wasn't a major difference and was a tight fit with the tape. I supported it from the ceiling because it has a little weight to it but that's a good thing. It actually looks nice, too bad it's mostly covered by the other ducts. Love the fact that it has a speed control on it, makes it more adjustable. It's not just 3 settings, it has "off" and all the way up to high is incrementally adjustable. It pushes some serious air. Without it attached to the duct work, it seemed like it was pretty loud on high but with it attached, it's no louder than the furnace. I also got a BN-LINK Heat Mat controller because the one at the store looked old, clunky and awkward. It was also more expensive. So I got that and it works great when the furnace is on and turns off when the furnace turns off. I'm happy with the setup and the price. Tenants love it because it makes that bedroom and bathroom warm like the rest of the house. Sorry for the long post but I like to give credit for a good product and show how I ended up using it.

Very pleased with this fan. I have had one for 4 years running almost nonstop and it runs just as well as a new one. The controller do high to low is great as well. I use it as an exhaust fan on my laser cutter and it is perfect for that.

I bought this S6 fan to create some circulation in my basement The fan works well and seems to be well-made. My basement is about 2000 sq feet and is chopped into these three main areas: Space A. Unfinished area (about 350 sq feet) Space B. Main living area (about 1200 sq feet) Space C. Exercise/rec room. (450 sq feet) Space A connects to Space B via a door. Space B connects to Space C through another door. Space C does not connect to Space A directly. We have a humidity/mold problem throughout the basement, so I installed a dehumidifier in Space A. I wanted to pull air from Space C over the wall into Space A then push it out to Space B and back to Space C to complete the cycle. I am hoping that by circulating some air through space A the dehumidifier will dry out the whole basement over time. My dehumidifier is rated to process 160/190 cfm on its two speed settings. So I bought this 265 cfm AC Infinity S6 fan and 8' of 6" flex duct from AC Infinity as a circulation fan. My configuration is as follows: I cut a a 6" round opening in the Space C ceiling. I put a 90" hard elbow there and attached the 8' of 6" duct that terminates in Space A. In Space A at the other end of the duct I mounted this fan onto a 12x4x6 90-degree register box and a 12x4 diffuser. I hope to pull over some air from Space C past the dehumidifier. Issue: After completing the install, the noise level in Space C at all fan speeds (where the intake vent is) is higher than I would have liked. I measured some dB readings with my iphone app and here are the results. [NOTE: For reference, in this next part I am looking at the speed control's dial like a clock face, where you have the "off" position at the 6:00 (bottom) position. Then "Low" is at 8:00. "Medium" is at 12:00 (top). And "High" at 4:00 position.] While the controller seems infinite, there are really only three or four distinct areas of power/noise: At the 8:00 and 9:00 position, the noise level in space C is about 40 dB. At 10:00 position it jumps to 49 dB (nearly ten times louder). At 11:00 - 12:00 it is about 52 dB. Then at the 1:00 position it jumps to 54 dB and doesn't really get much louder from there. Recall that the dB scale is logarithmic, not linear. If there is a relationship between noise and cfm, then between the 1:00 position and 4:00 position, it seems there is very little air volume increase. I am not an HVAC engineer nor a sound expert, but it seems you have a low 40-ish dB setting, a low 50-ish dB setting and then a 54 dB setting, all as measured on the inlet-side vent, which for me is 8' from the fan. I would like to make it quieter in Space C because my wife spends a lot of time down there, and she doesn't tolerate noise well. I don't really care about the noise level in space A, as it is not occupied and the dehumidifier (generating 52 - 54 dB) is in there too. But for reference, with the fan attached right to the register outlet box, the noise levels in Space A (without the dehumidifier running) are 2 - 4 dB higher than the above readings from under the inlet vent in Space C. Note: I have 9' basement ceilings, and I took all measurements directly beneath the vents at 5' up from the floor. Not a scientific result, but I hoped to give you all some idea of the noise levels.

This review is for AC Infinity RAXIAL S8, Inline Booster Duct Fan 8” with Speed Controller - Low Noise Inline HVAC Blower Can Fan for Basements, Bathrooms, Kitchens, Workshops. The fan was delivered on-time, complete, and as described by the seller. It was well-packaged in a custom box and included a user manual, 2-year warranty information, and hardware for mounting the speed controller. The cylindrical structure is sturdy and nicely finished, the plug-in power cable and speed controller are integrated and the fan runs smoothly with little vibration. The speed is continuously variable with a dial control from OFF to maximum; at highest speed it makes about as much noise as a pedestal fan….. the sound is principally from the airflow itself. The fan has steel blades and is designed to be mounted/suspended inline in an 8-inch diameter ductwork; there are no mounting brackets provided. I am using this fan, funning at medium speed, to increase ventilation in my attic with the expectation of improving the efficiency of my A/C system (also installing a reflective radiant barrier throughout); so far I am satisfied with the performance. I am using an Amazon Smart Plug with the Alexa application to run the fan on a regular routine and/or use voice commands to turn on and off remotely as needed.

Sucking or blowing this fan works well. The noise level is very low and cant be adjusted more with speed controller, not heavy and easily installed alone. The fans power and air flow are perfect for the size of fan.

The product was exactly what the ad presented, size, colour, easy to install, etc. Installed it a couple days ago, was great! Quiet, speed adjustment....and today it just quit. Not sure if it iver heated or what...no burned wires or smell...nothing...just stopped working! I will be returning it and expecting a complete refund! Disappointed! **UPDATE ** After contacting AC Infinity, who were super friendly and helpful saying tgey would ship me out a new fan but have a quality check before they sent it out. I thanked them for offering but I decided to go a different direction for what I had originally purchased the fan for. Long story short...I shipped the fan back to Amazon and received my refund in just over a week. I most likely will give the AC Infinity fan another go in the future!!😊

Plugged in, switched on, 3 seconds and smoke comes out from the fan. Completely dead, so far had to pay £30 to ship it back, waste of money and time, bad experience. Got a German's made, works great. Germany-USA 1-0

Exelente producto me dejo impresionado su funcionamiento y estética ampliamente recomendado

Great fan only issue is that it came with a US plug. I needed it to have a UK plug. So I had to buy and extra 240v to 110v converter at £25. But it’s a great fan. Using it to power my home made humidifier on my mushroom farm. If it was adapted for the uk I would buy more.

het toestel heeft GEEN 230 volt wat ik verwacht wanneer je in Belgie op de amazon.com.be koopt en door belgische dealer wordt geleverd. klein foutje .... retour is direct aanvaard: wacht op de terugbetaling ....
