Ive just bought and installed the Timbecon DC-1750 With massive 1220mm tall pleated filter.
It is sold as being computer modelled and super advanced. Optimised I think it says.
It is incredibly powerful compared to my old 2hp generic. It is obviously far more powerful, for as a test it evacuated my cabinet saws impressive leftover dust-dune in under a minute.... Clean as a whistle. Happy! :)
There is a design element that bothers the hell out of me... Where the blower mounts directly to the body it:
-- attaches directly at 90 degrees, and
-- the inside of the body/barrel is simply a tube
Now, I expected that the inlet to the body would decline by 15 degrees to impart a downward velocity to incoming material. I see this design on Bill Pentz's cyclone. I see it on the Clearview and I see it on the better cyclones. So, why would that not be part of a dust collectors design?
Now to the part that REALLY bothers the hell out of me.... Dust comes in and only falls when it is heavy. All the rest goes straight up in to the pleated filter.
There is no internal ring (or "Donut") inside the barrel above the inlet, with a hole in the centre.
This is present on my generic 2hp which must be over 10 years old. It makes sense. It forces the material to loose energy and fall, where lighter cleared air swirls up the centre hole to the filter.
Why would they have left this off? Is a clear unimpeded tube better? (I think not, for a quick test of big bucket of dust left a considerable amount of it in the filter).
Would it be in my interest to make one and install it?
Lastly, if I were to add a "donut", should I also add a "wok"?
These articles discuss woks and you see the "donuts" present on every single one of them...

edit1: donut may be called a separator ring?
