A New Type Of Efficient Dust Separator ?

[Boyan Silyavski]

I see. I am also playing around with dust shoes, DIY separators, etc. I went to the conclusion that for my CNc the best is 2-3 stage shop vac LVHP and a hose around 40-50mm, no bigger than 60mm. I have very serious 2.500w 2 stage vacuum cleaner using 42mm hose that sucks very well.

These Chinese separators suffer from design flaws. One thing is that the dust rotates inside but will not go down until i stop the vac. Previously i had Thein Baffle type from a bucket like thing, it was more efficient. Though at that time i did not know to separated the area with a plate so i does not suck back the fine dust floating around.

Remove large debris (saw dust) from air flow is not an issue. Dust thinner than 20 microns is harmful for human lungs. We are not able to filter it.


I am using cyclone and reusable bag from HEPA filter in the intake of workshop dust collector Bag has a zip on one side for empty. Works good, however claims like 99.9% do not say a lot. Even "clean" room air has some dust in - would this device clean it?

The best way is exhaust the air outside of the workshop. This works well during the summer, during the winter we are loosing to much energy. Simple cross recuperater helps to harvest it back.

I am hobbyist. However I am surprised how much dust come through filter anyway. It colour the snow.
