Actually the situation gets confusing: the reports claim, that e.g. the Orky (http://www.orky.de/) does not clean dust very, but what I've seen myself is, that a filter in the air stream out of my Siemens vac, (sucked by the Orky )became grey in minutes, while the same type of filter (?) in the outlet stream of the Orky stayed absolutely white, after a much longer time. Conspiracy theories lurk everywhere - the only remedy is measuring ourselves... On 2014-07-17 11:11, Armin Faltl wrote:

Now that being said, we do need a better cleaning equipment at the metalab, and this thread kind of turned into a motivator to build one. I too, do not endorse the abuse of equipment. A vacuum cleaner with the outlined features is however desirable in it self (but see below).
Armin, just let me know when you'll be working on it at the lab, and I'll show up with one of the turbines, apart from that, I'm not sure how else I can help. At the moment, I'm pretty busy, so I can just supervise a construction and contribute literature like the paper about cyclones. Throwing together a (simple) model on my CAD system may be possible, but I don't like to promise it (soon).
So my approach is, to start with the frame and the gas washer. If we don't get the washer right, the entire project is doomed. The cyclone is there, just to prevent coarse material that might block them, to enter the nozzles of the washer. (A sieve would serve that purpose too, so it does a bit more ;-)

Well, after reading the 2nd test report, my enthusiasm for a water filter/ gas washer is more or less gone. Before we put any effort into that project, several points have to be clarified...
