Keeping hywin rails clean?

[mike os]

cyclones tend to be used to stop large particles clogging /filling the extractor unit, fine material tends to pass through the cyclone and into the filter bay/vac unit,, with coarse material dropping out into a hopper.. as you don't have coarse material I don't think it would work, but could be totally wrong with the right cyclone design.

Hope your extraction system has sufficient earthing to prevent static build up....if it is plastic I would be looking to run a bare metal strip in the ducting and earthing that

If your cyclone is efficient enough it should have no problem filtering the foam dust. You can always add a filter to the exhaust to catch what the filter misses.
