I'm all for, but you make it sound like it's easy as pie. Proper cyclone modelling requires a few factors to be taken into account doesn't it? Like the suction pressure, size of the air inlet and outlet, and a few other parameters.
It's enough mind abusing that people sometimes managed to write
over 100 pages about this topic. And
here is another dude that details the build process of a sawdust dust collector that uses cyclonic separation (the very object of inspiration for the dyson products).
However I have never heard of orcy, neither seems google. Is it similar to the technology of those industrial cyclonic separators used to clean gas using a fluid that's injected into the cyclone?
Anyways, I have two 1000W vacuum turbines that were pulled out of an industrial vacuum (a numatic I believe). I got them for a dust collection project I have in mind, don't know if a portable dust collector/vacuum can be designed to make use of them. If it does, it would mean more shelf space for me, a fun project to collaborate on, and a proper cleaning equipment for the lab ... However to reduce the noise, maybe as suggested earlier by Armin, a centrifugal fan would make meeting the requirements easier.
