A New Type Of Efficient Dust Separator ?

[fifa]

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.
