I got a VivoSun 8" inline with speed controller built in but really wanted a Vortex S Series. Sexy mofo but twice the price. No speed control tho and I have a Temp/RH controller I've been using for 20 years. 10 year warranty on those I think. Canadian made too I believe.

When I ordered the VivoSun I also ordered a $16, 6-8" hard plastic adaptor for it. F'n outlet on the fan is only 7 5/8" so I'll have to DIY a seal. Not a big problem but FFS let a guy know in advance why dontcha!
I have a hankering to make my own out of sheet metal. I have a big old soldering iron that I'll have to heat up with my tiger torch, plenty of solder and flux and the DIY skills to do it. Pretty sure I can find a pattern on the web. Could use pop rivets too and seal the seams with some silicon. My 6" no-name one is still chugging along so no rush. I wired up a ceiling fan speed controller for it and that works great. Wife has been using it on the fan for her incubator lately but done for now. I also have a 10A variac but use that mainly for cooking up my cocobudder running my still.
