RO 90 Static electricity

[aloysius]

Not sure why there is so much animosity towards Nilfisk.

My Festool CT22 was made by Nilfisk and when I stuffed up the motor I saved 40% by purchasing the Nilfisk branded motor rather than buying the one in a Festool box.

Regarding antiistatic hoses... other than colour (and price), can anyone spot the difference between the Nilfisk hose on this link and the Festool branded one?

I had assumed that my Midi is made for Festool by Nilfisk, am I wrong?

I'm sure the motors are common to many Kraut mfr's, but Festo's vacs have been made by Kraenzle for many years.  Part of their greater fourth reich.  The CT22 is a model Ventos 25 in the Kraenzle stable.  I've also heard of ppl using "Makita" vac motors in their CT vacs!

To achieve full a/s performance, all fittings;  hoses, connectors & vac need to have a resistive electrically continuous chain, and the vac itself needs to be earthed too.  Do you have proper earth continuity in your power supply?

Given that the baby Rotex is, unlike the others, belt as opposed to direct/gear driven it MAY be acting as a mini Van Der Graaf generator:  a device that purposely generates electrostatic potential often exceeding a megavolt!  Certainly enough to generate a healthy spark, and perhaps energise the Nilfisk/Alto's protection circuitry.

There's absolutely nothing wrong with Nilfisk/Alto/Wap vacs.  In fact my Festo SR5E vac was made by NAW & has been going strong since '95.

For what it is worth, Christian Oltzscher explains the importance of conductivity in more detail here

As an aside, although I am a UK customer, Christian has been instrumental in my having remained a Festool customer after I had issues with the early plug it hoses working loose. Top man- is he still with Festool USA?

Christian is now CSO for Festool (worldwide).

Thanks for the update Peter.

CSO? Chief Security Officer?

I genuinely wish him the best of luck.

A few years back, had it not been for his input/feedback (via email) I might not be an on going Festool customer.

The CT22 was actually a rebranded Kranzle vac. But Kranzle probably did not make the motor but ordered one from a specialised manufacturer like Nilfisk-Alto.

I had assumed that my Midi is made for Festool by Nilfisk, am I wrong?

The Midi and all other current Festool vacs are made by Festool themselves, they set up a special venture that falls under Festool's mother company, the TTS umbrella. But again, they'll probably order their motors somewhere else.

Not sure why there is so much animosity towards Nilfisk.

I'm not sure either, because there is none. Maybe not make stuff up.

Thanks for correcting me re the CT22, I guess that I had (incorrectly) assumed that it was Nilfisk given that they/WAP made the previous generations of festtol dust extractors.

Thanks for the feedback aloysius

I am not the OP and thus don't have the issue with a build up of static electricity. That said, the 90mm  has been on my wish list for a while.

I can report after several cumulative days of useage for different projects that I'm completely unshocked by it and glad to have moved this little machine from the wish list to my shop

If I recall correctly, there were issues with the original Dust Deputies mounted to Festool CTs'.  Static was building up and frying their motors.  they quit making the DD for Festool- shortly before I tried to buy one- until they figured out how to address the static issue.

Also, insurance companies and building codes require spark arrestors in the dust collection systems of larger wood shops.  This isn't just a ploy.  Static electricity can cause a spark powerful enough to ignite wood dust and cause an explosion- albeit unlikely in the OP's case.

[member=9481]aloysius[/member] - while the ro90 does have a belt, I believe it is used for the Delta mode only.

I think it's still gear driven in its most aggressive mode.

The belt connects the motor (located in the back portion) to the mechanic in the front (at least according to the drawings in the EKAT).

  I thought the sander was belt driven regardless of what mode it's in since the motor in the rear is the prime mover/power unit and the 'gear box' up front just changes your sanding mode as you see fit.
I see we moved this discussion over to Ask Festool........ [smile]

Tyler confirmed today that the whole shebang is driven by the belt.
