Yeah basicaly they shouldn't ever realistacaly fail in your lifetime, unless abused/ run outside of spec.... the benefit of newer tech ones is they use less power, are more controlable, and don't make as much noise for a given rate of size/airflow.
Good info. I have a visosun 6". Nothing fancy but it does a great job venting 3 tents in one. I was just concerned how long it would last.
After reading folks posting these newer fancy versions with better environment control and energy savings make me rethink what I'm currently running. I may upgrade soon to a newer one. Black Friday sales are just around the corner. Thanks for sharing
Yeah I use my old ones for bottom air now...couldn't beat free.
I prefer 8" in my 4x4's...they run on 1 most of the time. 2 or 3 on hottest days.
I like the Terrabloom brands controller best and they've run 24/7 for 3 years with no issues.
Have some cheap I-power 6" that I can't complain about other than their controller sucks.
We were talking inline exhaust fans. In my experience, their oscillating fans are delicate. Slight mishandling can damage the gears. I have found vivosun exhaust fans more reliable in that regard. Nice if they've improved them but after the third one started clicking and getting stuck I switched.
