I see it only does 315CFM tho. Most 6" are in the 400-440 range. Can see why it uses less power and can claim the highest cfm per watt. Would be more than the 440 I have running at half speed so good enough for my needs as they stand.
I'm using a ceiling fan speed controller done up in an electrical box with cords for my fan. Works fine and no pulsing or rumbling noise at all. The bearing is going in this no-name fan that I got used from a buddy who got it used from a buddy so no idea how many hours were on it when I got it. Dirty as hell when I got it so lots of hours I'm guessing. Buddy was running it full bore for months with the fan pushing air into the carbon filter and he lives on a gravel truck route 40 ft. from the road. Plugged the filter right up good and likely wasn't good for the fan either with no filter.
I have a heavy-duty 6" biscuit fan that works with the speed controller fine I can put into service with a couple of 6" round to 7x8" side take-out pieces of duct fittings that with some tin work, a few screws and some Gorilla tape could be put into service quick if this one craps out on me. Been noisy for a few months but not getting noticeably worse very fast. Won't be pretty but will for sure save my ass and might be a while before I'd bother to replace it.
This is it here hard at work.

The backup fan is on the bottom. Loud as hell but blows lots of air hard at full speed.

Need a bigger sump pump too.

Screw the haters. Got pain they need to inflict on others and a shitty outlook on life. View attachment 4134640
What haters? I said in my initial post that hyper fans were less powerful than most inline fans but use half the wattage.
