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 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

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.

Pretty great fan, it's really not loud, I tried a lot of them, and this is very quiet, almost not hearable at the lowest speed
