So, I have no experience with the big CFM flowing towers, aka those dust collectors with a plastic bag on bottom and a textile bag on top. But my logic is the following:
That type of dust collector moves BIIIG quantity of air, however it has 0 suction power, so the more you restrict the airflow, it gets exponentionally worse at moving air. For example they are mostly 100mm hoses, and for the CNC, for example i use the LR4, has i think 65mm inner diameter for dust hose, I run a 70mm hose, it grabs the outside of the shoe and somewhat fits. However I run a big shop vac, a raider DC-02, paired with a vevor cyclone. Both have 100mm pipes and hoses, and then from the vevor to the CNC i run 4 meters 70mm. The vacuums have less CFM, but they have SUCTION, aka vacuum fource. As soon as the brushes from the dust shoe get within 5mm of the material im cutting, I can hear the metal drum on the bottom of the separator pop, aka cave in a bit. I have basically 0 dust left after cutting on the table, 99.9% of the chips are in the cyclone bin, and that 0.1% is very very fine dust which goes in the vacuum bin, seems like only MDF manages to clog my bag in the vacuum, but one quick blow and its back on. The vacuum also has a hepa filter and two bags to put over the filter for finer particles.
Its not fully perfect, I think the vacuum is even too strong for this cyclone, even though its hte biggest i could fine on a budget. Vacuum was 80 euros, separator was 100 with the metal bin underneath it. So for this price i Can’t complain, its doing a perfect job.
EDIT:
Forgot to mention, they claim 100% antistatic, BUUUUULSHIIIT. I’ve ran so much wiring to ground this thing, a lightning zapped me from 10cm away, before I did that, I grounded the cable that goes to the CNC, but after the dust enters the separator and starts spinning, it starts charging static in the cyclone plastic and in the bin. CNC is safe, but the bin could have set on fire with all that wood in it, after grounding the cyclone seprately, No more static anywhere.
