Dust separators - why can't you just...

[Grahamshed]

I have just bought a camvac 286 and want to make a separator bin. I know ( in principle ) about cyclones, and Theins, but why can you not just have one pipe from tool to bin lid and another from bin lid to vac with a filter over the bin end ? Is the cyclone 'funnel' or the Thein 'slot bit' really necessary ?

You can and I did - with a plastic dustbin. Most of the heavier stuff fell to the bottom and stayed there, the finer stuff just carried straight through to the vac. Having a filter over the outlet to the vac. helps to catch more but the snag is it needs frequent cleaning.

As did I, but the Thien and cyclone separators remove more of the fine dust...
