Inadequate pressure in cyclone dust colector

[Prairieboy]

.2KW is about 1/4 horsepower. Even the simplest dust collector systems boast at least 1.5 horsepower. A Dewalt shop vacuum uses a 15 amp motor, this translates to 2.25 HP or about 9 times the power you have. ( 1.8 KW )

It sounds like you are severely underpowered. I am assuming that you are not connecting this to a duct collection system, but rather connecting it directly to a single machine.

I would recommend you drastically increase the size of your motor. 1.0 kw minimum ( 1 1/4 hp ). 1.5 KW to 2.0 KW would be even better. You should also check if there are any leaks in your connections. A vacuum system can be hard to troubleshoot. A simple way is to take a candle, light it and then blow it out, the smoke after you blow it out would be sucked into a leaky joint. There are special candles sold for this purpose, but an ordinary candle will still work.

If you are connected to dust collection piping system, you can also optimize the system by insuring that there are no 90 degree bends, no connections that have the ridges pointed away from the vacuum itself, no corrugated piping and the piping is large enough, i.e. matched to your dust collector capacity.
