The rotation of water down a drain has everything to do with the earths rotation. You can force it to spin anyway you like but if you let it choose it's own rotation direction it will always go clockwise north of the equator and counter clockwise on the southern hemisphere. This might have small effect on a dust sepparator but then again it might be just the sort of thing wich makes it work just good or that makes it work Great! I gather noone has tried switching direction to investigate this then.

Thien Cyclone Separator Lid Discussion / Equator
June 02, 2012, 10:31:22 AM
Hello to you all. This is my first entry in this forum wich topics; spinning dust into cans :)
I am a full time construction capenter. My main dust producing tools are the miter saw, electric hand planer, hacksaw, rotary sander and bench drill.
Since I am moving around alot betwen smaller projects I try to travel as light as I can. This is why I bought the smallest of the Festool vacuum machines The Festool CTL Mini. In europe this model has the same motor as the bigger models and just about the same extracting capacity. The biggest model extracts 3.900 liters (1030 gallons) per minute and this smallest one that I bought extracts 3.700 liters (977 gallons) per minute.
The downside is that it has a small dustbag at only 7.5 liters (2 gallons). This is fine for tidying up some breadcrums but for collecting dust and chips from a miter saw or planer this will not work. I will have to build a good dust separator for this. I've studied videos on youtube on the Dust Cyclone and the Thien Extractor and have made some plans for the one I'm going to build.
I hear great things about these extractors efficiency and I hear some people that have alot of problem with clogging and such.
I meditated on how this thing works and realised that it's pretty much the same dynamics as in a low preassure weather system, a tornado or - a cyclone.
When I pull the plug in my bathroom sink, the water goes down with a clockwise rotation. It's known that on the other side of the equator it's the other way around, same with weather systems.
I don't know the importance of this in building a dust extractor. But does anyone has any say about the rotation direction of the airflow when building one of these extractors?
Thank you /Bramberg
