    • Perfect
Size: 6"
I bought this to use as a fresh air intake. Works perfect. Extremely quiet. Metal blades move a lot of air. Also works perfect on a timer to run a min or so every 15. Some of the other reviewers made me a little leery but it runs perfect and seems very well made. Thank you AC Infinity!

    • Used as ventilation fan
Size: 6"
I have run this fan continuously for 6 months straight every single year for three years now. My power bill goes up about $2.75 per month when I do this. Zero problems with bearings or speed controller. I installed it to draw hot air from the top of a room with a wood stove and blow it into a cold back room. On wide open speed the fan is a bit noisy (short duct work has no turns in it). But I only run it at that speed on the very coldest February days. Tuff little fan. Love the speed controller. It replaced a single speed duct fan that had only lasted 2 years before the bearing gave out. Only negative I have about this unit is fits loose in standard 6" diameter duct piping. Did I tell you I love the speed controller? ... show more

    • decent performance and price. too loud.
Size: 6"
This is a nice quality fan for the price. moves a decent amount of air. Had mine over a year and still working good. Its a little bit too loud for me but not any louder than the competition so its as expected. It has a nice dimmer for adjustable fan speed. Nice colors also. Next time will probably go for the cloudline. ... show more

    • A really decent unit that is low-noise
Size: 6"
This unit is really nice. It has a solid build quality, and runs very quiet in compares. Pushes a good deal of air as needed. The speed controller is of nice design, even has a little light on to show when its turned on. It fits inside a 6-inch duct easily enough (maybe a bit too loose?). Both ends fit inside the 6-inch duct ends. Various ways you can affix it from there. I bought this as a second choice after wasting twice the money on a different unit from a different maker (which that other thing was so noisy you couldn't be inside the same house with it running!). ... show more

    • Powerful, quiet fan
Size: 6"
I got this for my grow tent setup. It’s not huge, so I didn’t need an actual inline fan, but I did need something to exhaust hot air. I’d tried another brand before this one, and kicked myself because I should have just gotten this one in the first place. The other one sounded like a jet engine on the lowest setting. This one moves a good amount of air while also being quiet; I notice it when it first starts up then it fades into background noise. Before I added this fan, my tent was getting close to 90°, even with 2 small fans blowing. With the fan, my tent stays between 76°-79°. ... show more

    • High Quality and Easy Install
Size: 6"
The Inline Booster Duct Fan 6” was well package. I like that the body has no seams. It's all one piece. Fan seems higher quality than the cheapo replaced that was 1/2 the CFM. Used it on my HVAC duct work coming from the furnace. Short run with 3 elbows. Was a little surprised the existing fluted 6" furnace pipe would not slide into the wider side of the fan housing. Ended up working out great as the fan can fit into a pipe that is cut in 1/2. That way you can expand the pipe outward from the fan body as needed and you can get it into really tight spaces. Make sure you have some aluminum tape to seal. Fan on max I'm guessing tripled output. Noise not much different than existing sound from vents at least for me as furnace in the basement was not too far from 1st floor room. If you have loose duct work, that volume of air pushed might make more noise. I don't. ... show more

    • It works
Size: 6"
It is a little noisy on the high setting but is working great to even out the house temperature, before the back half of the house was always warmer than the front half, now i can't tell the difference.

    • Quiet motor but loud wind noise
Size: 6"
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. ... show more
