Diy cyclonic dirt seperator from pvc bits and a bucket

Step 5 BONUS.. videos... Web rebuttals.... improvment ideas

OK first off all i built this knowing of a couple of products already on the market
like this and that was stolen from here i hadn't seen this design but seems to be more of a general separator from what I've read
i didn't have $50-$1200 to spend on something that's easy enough to build from leftovers



the camera has trouble focusing on the small particles flying by so fast   but you can clearly see a downward counterclockwise then i tried some toner it adheres to the plex blocking the camera view



in this video you see the cyclonic action is good at the bottom of the chamber and more chaotic at the top the ability of this design  and the  size wight of the stuff your trying to separate is key to success  it works great up to a point  heavy objects just drop heavy aerodynamic objects spin around and drop  lighter particulates have a 50/50 chance of going out or down (this is where improvement is needed... if you need hepa3 grade separation)




at the beginning of this video we see a chunk of something stuck in the vortex  my guess is the cyclone vortex is started by the constant air exchange from the higher volume lower container to the lower volume upper chamber  this would also explain the chaotic flow at the top as the effect dissapates up the chamber ..why better designs have a v shaped chamber to pull the effect closer to the intake (how do you do this with pvc ? progressive reducers?) then various toner tests trying to catch the vortex without dirting up the plex



results the smaller the particles (toner is as small as.03 micron) don't collect as well


possible improvements : spiral intake after a cubed chamber ...multiple vorticity chambers 
more of a total startover if i wanted to goto a much higher separation  but ill see what i can do with what i have available without scrapping what i have
