8 inch metal duct fan from Amazon.

I have purchased two of these in the last 3 to 4 years and they have ran almost non stop for that amount of time. That being said, both of them have gotten so loud that I cannot use them anymore. What are your experiences with this fan.

    • Yes, they do wear out. Good solid work horse, though. The 6 is anyway, not much experience with the 8. But vivosun is pretty basically good stuff. 24/7  3 to 4 yrs is really good for any motor.

      • That's the one I have 2 years perfect no problems with 8 inch.  I got the kit that comes with 8 inch carbon as well must of went down I paid 215 for 8 inch inline and carbon this is a great deal though

        • I have one of those from a different manufacturer, or should I say different label on it, typically my luck with electrical things from Vivosun has not been good. The one I have has been running nonstop for 2 years now. My only complaint is the 8" ducting doesn't fit well on its own so I had to use duct tape to seal it up. I am deaf so the noise doesnt bother me, no complaints from my wife but I am deaf so I may be missing them

          • i had 2 of those and i replaced them with ac infinity fans and never turned back. i use to hang them with bungy cords to quiet them down a little.

            • They do have top shelf fans, I still use the 3 AC Infinity AIRTITAN T7, I used on the bottom of a grow cabinet pulling air into my grow room and they are at least 5 years old. 2 of them died a few months after I bought them but they were replaced with no problem and they are still running strong with 0 maintenance

            • I agree it is a loud bitch and used aluminum tape to fit on carbon because it kept slipping off.  Next big grow I am going with ac infinity

              • So I guess I  should be happy with the life I got out of them. Anything with Chinese bearings and brushes doesn't last forever. CPW to your comment I have had piss poor life out of multiple vivosun 8" carbon filters they didn't last two grows before my whole place smelled of dank.  I went with ac infinity and they are better quality. Oh well live and learn.
