I have decided on buying a Camvac 286-3-wall extractor, (originally I was going for the 286-4 but I've changed my mind, simply because the drum will fill quickly when using my planer/thicknesser) because we may be moving house this year I intend to mount the extractor in a purpose built frame on castors, it will be connected to pipework with branches to bandsaw, tablesaw, planer/thicknesser, bench sander and pillar drill, I will probably also have an open end just incase I need one, all branches will have gate valves fitted. If I've got it wrong will someone tell me as dust extraction is a bit of a minefield to me
I will be use 110mm soil pipe and flexible tubing as I have these to hand, my question is how do I earth the system, do I run a wire from each machine along the pipework to a screw which is screwed into the soil pipe then terminating at the extractor, or do I have to actually wire the earth connected to the earth pin in a 3pin plug?
