AC Infinity RAXIAL S6, Inline Booster Duct Fan 150mm with Speed Controller

Have this hooked up to the far end vent for a Bambu P2S printer to exhaust toxic fumes. Yes the instructions say don't use this for toxic fumes but I figured if thousands of others have been using this for their printers over the years it must be ok. There aren't a ton of toxic fumes, and they're not flammable fumes either. I would not use this for flammable fumes. It moves a decent amount of air once it gets to the midway power setting. On max it move a little more but this doesn't need to be hair-dryer speed to do it's intended job. Yes it's a little noisy if you don't have any vent tubes hooked up to it. I have it midway on power and connected to a flexible 4" dryer duct on one side and a tin dryer duct on the other. I can hear it from 5 feet away but barely. If you've ever been next to a RADON fan it kind of sounds like that...super muffled. It's right below our master closet and if I stand in the closet and purposefully listen, with no other noises going on, I can barely hear it but I know what I'm listening for. The spousal unit has not noticed at all, and she's in there a lot. I think that's her safe space, not that she needs one mind you. But with the clothes everywhere it helps to shut out distractions and noise and I see how it can be calming to hang out in there. Back to the topic--Once you turn it on it seems to start at 100% power, then quickly lowers power to wherever you have it set. Nothing wrong with that, just wanted to point it out. I have it plugged into a smart receptacle, so I can turn it on from afar. Should come in handy if I forget to turn it on and start a print and leave the house. Can also monitor energy usage, but I don't think it draws much. The housing is exactly 4" diameter, the exact same as most hard/tin 4" ducts. This is a little annoying. I have it connected directly to an outdoor dryer vent, and the tube that came with that vent is the exact same size as the housing, so I had to buy a short super thin adapter and clamp the vent to the adapter, then the fan to the adapter. I did get a 4" flexible dryer duct attached to the other side, little challenging but it fit. I only use about 4ft of the flexible duct, then it goes to hard duct and runs across the room to the printer.

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.

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.

I did a great deal of looking around the internet for user feedback on this fan. What I found was not stellar. However, nobody was steller that had significant feedback. The cheaper units had worse ratings. So, I went with this unit and paid a little extra. I'm quite pleased with this unit after receiving and getting first hand experience. I will list below what I found. 1. Built well and not flimsy. Not a peice of junk! 2. Not excessive fan noise like some of the reviews. The fan noise was not a problem at all. The house HVAC is louder than this fan on full setting. 3. Did not measure the CFM. However, output was more than the replaced fan while being quieter. 4. I cut off the speed control and operated it at the full CFM @120VAC. The speed control worked just fine. But, I didn't need that.

Good, solid construction. Moves a lot of air. The fan itself is no joke, so if you use it to vent a grow tent like I so you may want to cover the outlet with mesh. My only (minor) gripe is that there are only three available speeds instead of a potentiometer you can dial in more precisely.

So I tried the hon&gaun, ac infinity raxial s6 and ac infinity cloud line pro s6. The hon&gaun definetly moved the most air for the money but it was the only one that I could here the motor running both standing next to it and at the end of the vent over 20 feet away even running only 40%. But even at 40% it still moved a lot of air and there was not too much turbulence so the air noise was minimal but motor noise was loud. I really don’t recommend this unless it is somewhere we’re the noise doesn’t matter. The ac infinity raxial was the opposite, a bit more money, moves far less air, the motor is silent but the lousy impeller creates a lot of turbulence creating a lot of air noise that is mainly heard at the end of the vent. Last was the ac infinity cloudline pro, it’s far more expensive but far superior, moves lots of air, motor can’t be heard even standing right next to it and the air flow is smooth and quiet. It also offers optional WiFi controller that is very easy to use, can control up to 4 fans which can be controlled by your phone, by set speed, schedule, atmospheric pressure readings, temperature or humidity. This allows you to put the probe in a vent and have the fan only run when ac, heat or humidifier are running.

This fan has exceeded my expectations. I installed it in under 2 hours. The cutting of the duct and pulling it down took the most time then the fan nicely fit into both ends of the galvanized duct. The cord is long enough to reach an outlet about 6’ away. The fan speed adjustment is another great feature allowing a lower speed in the winter if needed and a higher speed in the summer. I’m currently running it between low and medium and will probably adjust as needed. I have a 22 x 10.5’ bonus room above the garage with 3 vents that doesn’t get enough air flow. Cold in the winter, hot in the summer. The temperature difference before the fan install varied 3 to 6 degrees hotter from the temperature on the main floor during the summer. After the install the temperature in the bonus room is about 1.5 degrees lower than the main floor with the fan continuously running. If needed I can slow the fan to dial it in. I have purchased a pressure switch which will bring the fan on with the furnace blower. I will be installing it this week.

This is a good inline option for the price, doesn’t move the most air but it’s pretty durable. Not too heavy easy to instal. There are better options but this one works for the beginner

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 ....
