I can't spend too much time explaining as my mother passed away on Sunday but I can tell you my system piped in all 6" pipe can take a 25' rule from any outlet and suck that baby back to the DC unit without issue. So how much do you really need or want? As for static the only machine I notice any feedback is my spiral head planner. I will be running bare copper around my lines and outlets to a ground source later on. I'll also say my basement shop stays about 68-70 degrees and maybe 40-50% RH.
