I would say that 100mm hose extractor will do the job ideally.

There are 2 ways that to be done- high pressure and low pressure. In both acases its important all to be grounded or there will be an explosion from the static electricity especially if a plastic job is done. And believe me even the shock from it is much greater than the typical static shock we experience entering or exiting cars or similar


High pressure

The cheapest high pressure is 1000W and around 100 euro/gbp here or similar. Problem is high power consumption and noise.


If i was going that way I would rather buy 3 stage vacuum motor and design a simple enclosure to silence it mounted directly on top of separator on top of 200l barrel. I have done that in the past and works like a charm. The separator and enclosure is very simple to design and make from MDB

here is the motor:





Problem with the above is they make noise, so have to be isolated and they have high power consumption, plus have to be ventilated outside otherwise they heat the room much.



CLARKE Woodworker DUST EXTRACTOR 1hp could be the other solution. Again separator must be build on top of the barrel as there are no cheap ones for 100mm hose size/ if any/ . The original bag is crap, it will not collect fine dust.






I am in from of the same problem now and for the moment i use a shop vac and dust separator on top of 200l barrel. I don't like it for the high power consumption, small diameter hose and the noise.



I am thinking also about a smaller wattage tangential motor like 350W mounted on top of DIY separator on top of barrel. My friend has the same setup and reports its good. I will go these days at his shop to see with my eyes if small motor could evacuate the fine dust and small chips.
