AC Infinity RAXIAL S6, Inline Booster Duct Fan 6” 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.

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.

They're quiet, the speed control works well and the power draw is quite low (~40W turned all the way up.) Airflow performance is as expected given their size and power draw. I use these as automated supplement boosters to balance rooms where, for example, there's a computer that's on some times and not others and similar where full zoning is not necessary (my home automation can handle controlling it.) They work well for this provided you have reasonable expectations. If you have flex duct make sure you secure it with heat-rated ducting tape (UL rated) to the INNER plastic jacket on each end, then a wrap around the insulation so you do not lose performance or generate condensation. Other than that installation is easy. One failed after three years -- appears to be a bearing failure as it got quite noisy thus it was replaced. The others are all fine and continue to work as expected. Given the quite-reasonable price, variable speed control and that they're quiet and do the job of moving air as you'd expect I give them four out of five stars, with the last one docked due to the failure.

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 long term review. I purchased this in 2020 and it's been running pretty much non stop since. That's 5-6 years!!! I like the metal construction, perfect for an exhaust for my 4x4 tent and 3x3 tent at the same time keeping temps nice and cool. Relatively lightweight and the perfect size for the standard grow tent. Easy install, just turn on. My only "gripe" would be the adjustable speed dial. I can really only get two fan speeds out of it. it's full blast, medium or off. No matter how much I fiddle with the knob. 6 years and going strong. I'd absolutely order this again. Although I'm hopeful it keeps working for another 6 years.

I can say the the fan does work, does move a nice amount of air IF you're not connecting it to any ductwork. As soon as you attach a duct, there goes your cfm's....and a lot too. The motor is very weak for it's size. I attached a 2m 8" flexible duct to help get some outside air into the grow tent. the duct has only 2 bends and this fan is already struggling to get the air in. Let alone connecting some sort of filter to it. I guess I will need one more fan to help the first one out, one inlet and one outlet. Also the fan blade which came with the unit is NOT as shown in the pictures at all. It's a very flimsy thin material blade and when I received mine it wasn't straight. That caused the fan to have excessive vibrations. I removed and tried to straighten the fan as much as I could an now it's kinda working better, no (or a lot less) vibrations. Overall for the price I paid for 2 I think it has the same effect as 1 of the more expensive 6 or 8" models.

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.

Awesome product. I purchased this fan 6 years ago and installed it in the garage so air flow will continuously move. 6 years later original fan worked but made a bearing noise. Please keep in mind the original fan was on for 6 years straight only being turned off in winter months (3 months off) that's 54 months running time. That's roughly 40000 hours of running time before bearings started to make noise. Awesome product, Awesome price! I just installed new exhaust fan took less then 5 minutes. Great product team! Quiet,moves mass air to keep garage cool and vented. I appreciate your product. To makers 40000 hours of proven running time. And the old fan is still functional but makes a little vibration through the walls. So I ordered new one to keep garage vented. I thank you for such an awesome HVAC fan. 54 months running time that's comes out to $.92 a day cost of fan! WOW!

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 ....
