I cut 6 lengths of 2" PVC pipe with my table saw and later cleaned up the PVC shavings with my CT. I used my anti-static hose and didn't notice any static electricity produced while doing it but wondered if I should do any maintenance on the CT and/or the filters? It wasn't that much to clean up but wondered if the PVC presents any danger of static buildup in the bag or filters? Or, is it possible that some of the PVD shavings have remained in the hose?

Just the static electricity generated by PVC/plastic sometimes, especially in winter when the air is dryer. Didn't think there would be a problem since the hose is anti-static. I also wondered whether the PVC dust would cling to the insides of the hose like it seems to cling to everything else. Won't worry about it, especially since it wasn't that much.

Hi Randy
I have just done something very similar in the workshop. I use my Kapex for cutting plastic pipe and have just been cutting 2 1/2" clear tubing (not sure of the exact species of plastic) that I use for my HPLV dust collection to which my CT26 is attached and was in use for these cuts.
I have cut all sorts of nasty stuff, including fibreglass rod and cardboard tubing, and I have never had any worries at all. My complete system is grounded.

I've been cutting all sorts of plastics for 36 years and only recently with anti static vacs and hoses...other than a disconcerting rap once in a while. I cut virtually every type of plastic used in the modern world; acrylic, polycarbonates, ABS, PVC, nylon, and phenolics (wear dust protection with the last...nasty epoxies in those)
Fair question as the Festool Dust Extractors are more sensitive compared to a standard vac. I zapped my CT 22 control board within days after installing an Oneida cyclone. I have since grounded the hoses connections on the mini cyclone back to ground for save measure. Glad I did as I used the CT22 with a planer yesterday and could not walk within a foot of the Festool hose without the hair standing up on my arm.

Yes, the hose I stuck on it to try out my new planer was the silver non anti-static version of hose. Its the only hose that would reach (7 meters).
The Festool CT is heavily grounded with extra grounding at all connections. But I have got static introduced by the cyclone (UDD) regardless of hose which is why I am heavily grounded.

I have the Ultimate Dust Deputy and have not experienced any static issues at all. Your configuration, with the non anti static hose, should not affect the UDD and CT which should share the grounding via the short hose from the UDD that goes to the CT.
Perhaps you should just check that you have everything set up as Oneida suggest.
Because my system goes beyond the inlet to the UDD cyclone I have extended my earthing. I have an earth point, connected to the earth of the workshop electricity supply, to which I have connected copper wire that is wrapped around the ordinary clear plastic piping used in my system. I have not, but others might suggest that I should, put a metallic strip to continue that earthing to any connected hose (to which a tool might be attached). I chose not to do this as my earthing is designed to protect the CT not the tool.

Peter, the grounding on my setup meets and exceeds what Oneida suggests. I say this because it I worked with them on this when it happened. The retrofit came out after I blew the module up in the CT22 and there was several of us with the issue.
My retrofit came with a new hose (material), metal fitting and a black cyclone. The original UDD had a white cone that was used on the 5 gallon bucket kits.
My CT setup has a ground wire that runs between the inlet and outlet of the cyclone and then down to the inlet of the CT and then runs inside the machine and connects to earth ground connection.
I am not really having issues but my planer test over the weekend did exhibit a hair raising experience when I ran massive material through it with the planer and "non" anti-static hose. I am sure that was being dissipated as it got tot he cyclone.

Hi [member=18361]rrmccabe[/member]
Got it - Many thanks, I have the picture now.
I must say that after all that I have read about CTs blowing their circuit boards I was a bit worried when I had the original cheap and cheerful Dust Deputy. I bit the bullet as it were and decided to take the risk and ran it incident free for about 2 years. I then went on to the Ultimate Dust Deputy and do not give it a second thought.
If I ever have an issue I will be the first to tell everyone on the FOG.
The way that I continue my earthing from my 2 1/2" plastic pipe setup to the UDD is via copper wire wrapped around that tubing and secured at the ends and at intervals along the length with sticky metal tape. At my Dust Hub (where all the blast gates reside) I have an earth point connected to my workshop supply's earth. That is then further connected to a wire that is trapped under one of the bolts holding the black DD onto the black drop box below.

You are welcome Peter.
I am very happy with the UDD once I got past the initial issue.
Here are a couple pictures showing my grounding. They are made from copper and as I said all connected back to earth. The inlet to the CT has 4 studs all connected with wire and a copper strap on the side that the studs go through.
So far no issues

Those dead circuit boards in my opinion is nothing else just pure design error nothing to do with accesories or what so ever, i check the bag in my ctm36 hd model regularly after cleaning up debris etc and noticed from the first use that inside the container there was significant amount of static charge, machine is earthed hose does not collect anything that normally attaches to a charged surface, there is a little pin going inside the inlet port which is connected to nothing on the outside with a little bit of poking trough the vents and a bit of copper wire, there was an earthed connection inside the tub, 4 meters of bare copper wire attached inside in a circular pattern fixed the static buildup and no more dust coming trough the bags unless a large chunk of brick or something large and heavy flies inside and hits the bag.
On the topic i use the vacuum to clean up everything that fits inside the hose, as an electrician, debris from chased out walls, metal shavings, and so on, control boards seems fine as every function is working
