Grounding pvc and other dust collection myths Mar 26, 2018 · (MYTHS are itemized at the very end. May 18, 2015 · As of May 2015, there have been no known fires caused by a static discharge in a PVC pipe from a dust collection system. This is the most common fallacy in discussions regarding grounding. Jan 21, 2020 · After having done a lot of research on my own (in other words, I read some Internet articles and watched some videos), my personal feelings are that in my small home workshop in my garage, I’m not worried about PVC static electricity causing a fire. Because PVC is an insulator, you are more likely to get a number of small static discharges than a single large static discharge. It's hard to believe there's so much hype about grounding them. He uses logic, basic physics, and some equations to describe electron density, migration, and grounding within typical 4" PVC ducting attached to dust collectors. Here’s an informative article: Grounding PVC and Other Dust Collection Myths. May 14, 2003 · Similarly, the point of grounding attempts with PVC is not to remove charge from the dust. But Oct 7, 2021 · Grounding PVC and Other Dust Collection Myths Now, to your point about using highly sensitive electronics in the same area as the dust collector system, you are totally correct! Not only would the dust itself be harmful because of heat build up, but any potential or actual static would shock damage the electronic components. Grounding PVC and Other Dust Collection Myths by Rod Cole I am most struck by is how hard these guys have to work to get dust explosions in the lab. Even if you want to ground your PVC anyway, simply running a ground wire through the PVC will Nov 1, 2021 · Grounding PVC and Other Dust Collection Myths With some sometimes tortuous explanations, the author discusses the issue of static electricity generation in ductwork. . ) "Grounding PVC and Other Dust Collection Myths" WoodCentral Articles & Reviews There is a small risk of fire within the dust collector itself (from embers landing in the bin or bag), but there's no need to worry about the plastic pipes. Grounded metal ducts are used because discharges from metal to metal are often energetic enough to ignite dusts, and grounding prevents discharges from the ducts to other grounded items. It is not hard to get igni-tion if one makes a very carefully controlled, nonmoving cloud with just the right dust mix, and introduces a spark from a very carefully designed sparking mechanism. kwov yitqr rpbew ioxcr wqizyk zhejp idkuwafx lynmn fqyk otkuy |
