A conceptual demo of how a sawdust cyclone works. This was imported from AutoCAD from my shop project I made and tweaked and composited like crazy to make this video

Things to note-
The edges...mmmmm I love clean edges...
"View port" is tracked to camera for the see through effect.
This is heavily composited.
Cool. Now make a matching wigwam sawdust burner furnace.
