Topic tags/keywords: question vacuum hose static anti-static

So… been using the new track saw over the last couple days, and apparently the 16’ Bosch hose I got this summer is not the anti-static version. Not so much a problem with dust clinging to the outside of the hose like on my old shop-vac hoses, as it is getting zapped on the knuckles of the hand running the saw!

If I’m understanding things correctly, it’s not that I need some continuous grounding path all the way from the saw, thru the hose, around the Dust Deputy and Ridgid shop-vac, to a ground terminal, so much as just having a good anti-static hose to resist the build-up of static charge on the hose itself due to air flow. Correct?

Anyone here have experience with the Cen-Tec or PowerTech anti-static vac hoses? I’ve seen the Bosch hoses (the anti-static version) recommended various places, but their description doesn’t sound like they’d mate up with non-Bosch tools well?

I recently got a new hose for my Festool vac. I decided to save the money and got a regular, non-antistatic hose. Works like a charm.

I don’t know what the deal is with the antistatic vacuum hoses, why does one need one? Is it just marketing gimmick? Maybe someone can clear that up.

I bought the Cen-Tec antistatic hose and it is amazing. The multiple connectors is fantastic to fit both Festool and other tools. It doesn’t collapse and there is 0 static build-up on the outside. A little pricy but worth IMO (cheaper than the Festool counterpart for sure). Posting the link to the one I got just in case as Cen-Tec has many different hoses.

Sounds good. I am just still confused about static build-up on the outside of a vac hose. What does it even look like? Maybe I keep my shop too tidy to have experienced any dust sticking to my vac hose?

No Dust on the outside. Pure static electricity from the dust rubbing/moving inside the hose. Kind of like when you rub a balloon on your head creates static electricity. Same idea with the hose, which creates random shocks and pulling hairs on your arms when you get near the hose itself. It has nothing to do keeping an ultra tidy shop; if anything, you’d get even more since you’re capturing more. Another example is PVC ductwork for piped in DC systems; they generate static electricity as well and people will ground them just to stop that and potentially to prevent a dust explosion (there’s a post here on LJ about a real dust explosion event. Scary to read about it and I believe there were photos of the building if my memory serves me right).

You must live a charmed life ;)

This $40 Bosch hose I have doesn’t particularly have any issue with attracting dust – I have another that looks like a fuzzy caterpillar after 15 minutes of use – but getting shocked by the static on the knuckles of my hand inside the saw grip is less than pleasant. Not to mention a bit disruptive of one’s concentration while running a power tool!

The next step up appears to be the $80-85 Cen-Tec or Bosch anti-static hoses… I haven’t heard anything yet, here or elsewhere, that indicates that there’s a whole lot of difference performance-wise between those and the Festool anti-static hose @ 2x the price.

Thank you @Rayne for that link… you’re right, Cen-Tec does seem to have a lot of very slightly different products that sometimes makes it difficult to find the exact right one.

Ahh, silly me, it’s all about the inside :)

I had never noticed any dust built-up inside my vac hose, I should take a look. I have never felt any static though, neither did I have the hair on my arms stick up (maybe because I shaved too much of it off when testing sharpened blades!)

So what do you do if your hose is not anti-static and there is dust in there? Wash it out?

I don’t think anyone said anything about dust build-up on the inside.

I said some hoses end up looking like a fuzzy caterpillar due to dust on the outside from essentially ‘static cling’.

Maybe you’re just a more ‘grounded’ kind of person, so the static isn’t an issue for you ;)

Seems like someone suggested a vacuum hose cover a while back, i wonder if it would help keep static down?

I am very interested in this topic. I purchased the Makita cordless track saw earlier this year and Rockler’s small port flex hose kit thinking it would be perfect for connecting to my shop vac. as I was cutting sheets up on saw horses I threw the hose over my shoulder and down my back to keep it out of the way. I thought I was being electrocuted on the first cut I made. Not a pleasant experience. The Rockler hose has a metal spiral core and I was thinking it could be grounded but have not tried.

Do the anti-static hoses such as the Cen-Tech need a ground connection or is it just not necessary with the material they are made from?

Thanks, George

Anti-static hose like the Cen-Tec don’t need to be grounded. It’s the material they’re made of that makes them anti-static. I love mine. Deciding if I should invest one more. I have a dedicated one for sanding and may get one more to dedicate to cleaning the shop if the full 2-1/2” hose is too cumbersome to use (so far it has been and the original 1-1/4” hose is a static nightmare).

Thanks Rayne, I have an older Mr Nozzle hose that I use for general cleanup an light dust collection. I have never had an issue with static that I have noticed an do not recall it being specifically ‘anti-static’. When I hooked the Rockler hose to the end of it it’s a whole different story. So, I can see just the material making a difference.

This is the Mr Nozzle hose. Looks similar to pool hose. Very durable (as long as it doesn’t end up in front of a space heater) but can be a little stiff.

Yeah space heaters win that battle every time.

I’m just gonna throw out that it may not be much about the material, just where you have the material living? In general those who have a problem with a particular brand of hose, do you find yourself going POP all the time?

I only note any static at all, in mid Winter, and only if I walk through carpet, shuffling my feet, wearing thick wooly socks. Kinda where you’d expect it to be. In the shop I don’t notice any clinging, well, unless there is a spider web on something. I kinda think I’m sharing DrTebi’s experience.

That Cen tec anti static stuff looks kinda expensive to my eye, but it says this about compatibility.

“Adaptors are designed for compatibility with all major brands of power tools including Bosch, Festool, Milwaukee, Hitachi, Fein, cobalt, porter cable, black and decker, DeWalt, RYOBI and many private label brands of tools and dust collection shrouds”
