Static cling On DC pipe Question.
Barry Irby
>I ahve been revamping my DC system. I have PVC piping and never bothered to wrap the ground wire around it. The pipe has developed enoguh static to attract dut out of the air. Does anoyone know if wraping the wire around it will ellimanate the "static Cling" enough to stop it collectiong dust? If so, exactly how did you do it?

>Just leave it as is, helps clean the dust out of the air.

>Take a look at Bill Pentz's website, I spent a few hours there yesterday, the info is simply staggering. Everything you could ever want to know about any topic on DC. I also think more praise is in order for a fellow like that who put in god knows how many hours compiling and creating information solely for the benefit of the joe shmoes's of woodworking. Enjoy,

>Barry, I discovered the same problem when I built my DC system. Being a little bit of a clean freak, I first wiped the pipes down with anti-static cling papers that you use in the laundry. It worked. I then used anti-static spray for laundry. It worked. Then like Gary, I realized it was sucking very small dust particles out of the air, so I left it alone, but occasionally wipe it down.

>I ran unshielded copper wire throughout the ABS ducting and at both the far and near ends I attached through lugs bolted to this wire and some wire on the outside of the pipe to a grounded surface ( nearby machine).
Seems to work fine..
Gary's idea of using the pipe as a dust magnet might not be a bad one :)

>Won't work. PVC is a very effective insulator thus you'd have to cover the entire pipe in metal to be able to ground it. Duh . . .
The myth of grounding PVC piped systems was busticated long ago, along with the Internet legend of static dust explosions in homeshop PVC systems.
Let it go and vacuum off the accumulation once in a while.
it's not me!

>who you want to agree with, I think it was John. anywho, I was reading how someone used aluminum foil tape on the inside to ground the pipe (not to avoid explosions, but to avoid the occasional annoying zap) somewhere on bill's site.

>Before I moved, I had a grounded 1/2 inch lead foil strip down the length of all my PVC pipes. When I set up shop after I moved, I didn't bother with the grounding strip and I can't see any difference at all. Not only the pipes collect dust but the nearby walls collect dust too. I vacuum some of it off once in a while.

>Indeed; PVC is an awfully good insulator, with about 13 times the dielectric strength of air. You'll have more success attempting to ground your shop's atmosphere than its PVC ducting.

>Barry,
You can dissipate static buildup on the outside of your pipe by wrapping it with bare wire, then attaching the wire to a ground. I did that to control the static zap I was getting from the PVC pipe to my table saw.
