I have a ClearVue cyclone and use 6' PVC piping for my ductwork (yeah I know). We live in the Hill Country of Texas and in the summers especially have relatively low humidity (7" of rain so far since Jan 1 on top of the whopping 11" from 2022), so yeah it is really dry. I saw humidity down to 19% last week. My shop is in a 900 sf garage with one single insulated garage door. The entire shop is insulated on all 4 walls and roof with spray foam and is climate controlled to 72F in summer. There is a 6" concrete slab.
I know I need to ground my piping as evidenced by the collected fine dust on the PVC piping, but I am not sure how to go about it. I thought some of you guys have had this issue and /or know how to rectify it. I jump from my PVS pipes to Rockler (or others) expanding 4" piping that has a wire core. Dust collection is set up to the following: Table saw, router, drum sander, jointer, planer, band saw, and partially to drill press and miter saw. You can see a partial layout in the photos and also a close up of how static electricity is causing the dust to adhere to the outside of the PVC.
Open to all suggestions. IMG_0780.jpgIMG_0781.jpg
