Are you powering your vacuum/impeller assembly 1:1 with an FP motor?

As far as I can tell from the picture, it looks to be a centrifugal impeller system. The FP is just being used to spin a little metal disk like the one you’d find in your shop vac. It’s a low torque, high speed application that’s perfect for the FP. 1771 and 190 built similar systems in 2008.

Yes it is 1:1 drive using FP works great

Um, don’t take this the wrong way, but that looks like it really sucks. I mean that in a good way. :smiley:

What are the suction-cup type devices you’re using to make the seal with the ball on the sucker?
