Thread: Dust separator with cyclone cone from eBay

Yes I did and I made a series of 2min videos to explain the whole process I took.

Yes, I bought one of these separators. Mounted it to the top of a large plastic drum (blue) and then connected to a shop vac...works well and am happy with the result.

I made sure not to use a drum with a screw lid (but not sure it matters) and I did originally add a rubber gasket to ensure a good seal but it wasn’t really needed.

Drilled some holes in the plastic lid, strengthened the lid with wood and mounted.

Only issue I do have is the drum does have a tendency to distort when in use.

I have the original, Dust Commander, which originates from France ...



I switched to this from a Dust Deputy as the DC is anti-static. They otherwise work identically.

Yes, they work brilliantly. The Dust Commander is a direct steal of the previous design from the original Chinese developer. The brand is Sunning. A ring lock drum as used by Derek is by far the best collection bin. A lot of plumbing fittings can be used as adaptors and the scrap bin at your local specialist vacuum cleaner supplier is a good source of hoses and couplings.

Thanks for all the answers and the links.
Do you have recommendations for the size of the bucket? Or any suggestion where to find one here in Melbourne? I could find only small buckets at bunnings

I thought that Suning (correct spelling ) copied the French company, not the other way around ??

Jekkyl, the ring lock bin is also known as a "painter's bucket". They are not available from Bunnings. I searched around for mine. They may be available on eBay.

I have larger ones on my DC as well. Air tight, steel construction, and easy to seal and unseal.

Trade size paint used to commonly come in these 20L drums but I think OH&S concerns has made the suppliers shrink the larger tins to be more usually 15L these days. I have seen things like concrete paving sealer still coming in this size tin so they will be around. It's getting hard to go dumpster diving at building sites these days, everything behind fencing or in deep skips, but that's where I'd look around new house builds.

I created an insert into my plastic bucket but I have saved one of those 20L paint tins in case I decide to upgrade it or build a 2nd one. I'd inquire at one of those speciality paint shops to ask where to find empties.
I discovered that you don't need to seal the lid provided it is a good fit. This is because the vacuum pressure pulls the lid down anyway.

Does it have to be a round bin necessarily?
Can it be a box made of plywood instead?
I guess the shape does not matter as the vortex is created by the cone..correct?

Nope, it was the Chinese design stolen by the Frog. Tony (the Frog) and his brother were the biggest distributors of the Suning products in Europe and the UK, they just stuck a Dust Commander sticker on it. Their first in-house product was a direct copy of the second generation Suning cyclone that they had been selling.

When I first started selling the Suning cyclones in Australia I got an intimidating/threatening message from Tony, he and his brother are not very nice people. At this stage they were still selling the Suning cyclone. Once they started making their own I brought it to the attention of Ning Qiu (Suning) he was livid. Subsequently he supported me with selling these into the UK and the USA. This only lasted about 6 months by which time Suning had a huge number of retailers on board and he was no longer willing to do a special deal for me. Importing from him was always difficult because he didn't have the necessary export approvals (first time I had struck this) and this made container freight impossible. As time went on the cyclones were available on eBay delivered for less than I could land them for. By that time I'd sold about 1,000 of the various generations.

This is the only case I'm aware of of IP theft from a Chinese company. Tony and his brother are not my favourite people.

Interesting! Thanks for the history behind the design. I was not aware of it.

I doubt that the shape of the bin makes much difference.

I was using a round plastic drum as a separator for years and it works reasonably well. I then fitted one of those small cyclones to the top of it but was disappointed that it worked less well than the drum on it's own. Vac is 1100w and hoses to old and new setup were both 50mm. Ended up with less suction overall and more dust in the vac also. Have reverted to just the drum on it's own again.
