I currently have a 5 m 110mm soil pipe fixed to my low ceiling

I've fitted outlets to it with blast gates to provide extraction to:

Mitre saw
Band saw
Router table
Table saw
Thicknesser/ planer
40mm outlet to a shop vac hose.

At the other end I've connected up a Schappach HA1000 dust extractor

I'm wanting to change it to something more powerful most of the bagged type seem to be for chips, most of my waste will ge dust except the planer/ thicknesser...so what do I need? thanks
yes the camvac has lots of power , i built a thein baffle to go in front and collect most of the dust, mine is using an axminster workshop dust extractor, quieter than the camvac but its not got the grunt for a whole workshop, just used on my cnc, did lots of research first, kept as many sharp bends out as possible, and used 4 inch pipe throughout, just a bit of 4 inch flexi at either end. the baffle is great gets at least 99% of dust so you dont clog filters in the dust collector. build vids on youtube.

110mm for main run is great, doesn't restrict the CFM like flex or even 100mm/4".
If your worried about static sparks, just wind copper wire around it and attach to the metal of the extractor.
+1 for the 110mm pipe. My system sounds very much like curryjunkie above (incl the thein) although my vortex bin only really collects the bigger bits as I'm very fortunate that my fine dust gets vented outside. I have a 2hp single.

Mate of mine built his based on mine but split his workshop into two sides and installed 2x1hp extractors, one to either side. Suits him.

Both of us have never had any issues with static and, if I'm honest, don't know anyone who ever has with drainage pipe??....I would assume 'larger' professional setups would be using metal anyway.
