I didn’t but my ducting is metal and is in direct contact with the blower motor so no issues there. -- When you leave your shop for the night, make sure you can always count to 10. |

No. There are NO known incidents of residential/small shop explosions due to static buildup. None that we know of. Don’t worry about it. |

Another vote for not grounding PVC. I can often feel the static on the cone of my plastic cyclone, but rarely even get a shock from ant part of my system. I was thinking about it the other day, and I do have a basement shop, so the relative humidity is rather high (usually around 60%) so that might help explain it. If your shop is in an are with very low humidity, you may have more issues with shocks. In that case, I would go with metal ducts work. Trying to effectively ground an insulator is a difficult task. -- John |

Have been operating a PVC ducted system for 3+ years without any problems. I have not seen the need to ground the system. Running several machines using a ClearVue cyclone. -- Don't let perfection get in the way of plenty good enough |

I did not. This article from FWW offers some information that you might find helpful. If the link doesn’t work the article is from FWW issue number 153 from January 2002. The author rightly stats that NFPA regulations for grounding apply to dust collection systems 1500 cfm and higher, much higher than our typical 2 hp systems. We don’t ground or shop vacs which are dust collection systems of a much smaller scale. Some folks say they get shocks from their shop vacs but they aren’t of sufficient energy to cause combustion. I used PVC on my system and I don’t get any static even during the dry winter. |

Another vote for no. I am using 4” PVC, I questioned doing it (grounding) as well because a safety mechanism designed for industrial level dust has become urban legend and you will die if you don’t for every small shop or garage. Looking at my homes central vacuum system that has still not exploded to date and it just didn’t pass the common sense test for me. However….as a nod to the principle of static build up, I planned for a removable end cap at the further point away from the dust collector that I can remove and give a spray of static guard or fabric softener while the DC is running. |

I’d recommend grounding by wrapping wire around the outside of plastic pipes and connecting them to something metal that’s grounded. Static build up can be problematic in a couple ways. It can give some nasty shocks. My Dust Cobra repeatedly zapped me if I vacuumed large amounts of dust then touched the hose clamp so I had to ground that. The static can also interfere with electrical accessories such as Wixey readouts and mess up the readings. -- See my work at http://remmertstudios.com and http://altaredesign.com |

Try some anti-static hose.
