36mm anti-static hose leak?
« on: May 24, 2023, 10:25 PM »
Just got a new 36mm antistatic hose (I only had the 27mm hose with my CT 15)and I noticed that I feel air coming out on the end you attach to tools and other attachments (i.e. not the end that connects to the main unit). Is this normal? I'm concerned that I won't be able to use it in compliance with RRP rules. Thanks.

No, that isn't normal. You can check if the hose end is threaded on correctly by carefully pushing in the tabs with a flathead screwdriver, and sliding the ring up the hose.
At least that's how it worked with the older hoses, I can check later with the sleeved hose I have.

Huh, air coming out? You use it on the blower port?

Nope! It's in suction mode. I'm still trying to figure it out. My 27mm hose doesnt do it but it's not an antistatic one.

Me too. It's coming from under the plastic sleeve -- enough where it is noticeable. I called festool about it today and the guy I talked to said that their accessories arent leakproof and arent made to be like pneumatic vacuums (he referenced pneumatic systems a couple of times). I'm a little baffled because I thought their accessories could be use with RRP activities but I guess not.

I asked if I could duct tape around the sleeve to achieve a better seal, and he said that's fine, it won't damage the unit.

I would remove the tool end connector on that hose and carefully reattach it to see if that helps. Sometimes they slip and are not installed securely.

I would try that too.   Like others, I find it odd that air could be coming out of a hose that is under suction.   Seems like it should be the opposite.

Also, given that this is a new hose, you return it and get a replacement.

I would definitely not put tape on it. The fitting is supposed to be able to spin. This not only helps with the twist-lock feature, but it keeps you from twisting the hose as you pick up and put down the tool. It's amazing how much that can happen.
I'm still not sure how negative pressure inside a hose could cause positive pressure at a fitting? I could see it as a vacuum leak (loss of suction) at the tool.
