Curious about CT's with Dust Deputy and HEPA cert

[Kev]

This is simply curiosity from my part as I'm not inclined to turn my CT's into little Daleks [smile]

Does introducing a DD into the mix technically invalidate the HEPA rating?

I'm not after an opinion on effective DC, just the specifics on whether a Festool user could get themselves into trouble in a HEPA required environment if they were also using a DD.

Kev,

Interesting question.  My personal thoughts are that the air being exhausted will still be running thru the HEPA filter - so it will be clean - as long as the filter is ok.  Ahead of that everything is dirty (non-HEPA) from the hoses to the tools to the environment.

That's a good question. While I'm not sure that it technically invalidates the HEPA rating, we've had problems in the past where users have damaged the electronics of their CTs by using them with DDs. We don't recommend or support using any non-Festool accessories with Festool products.

I heard a rumour that the MIDI is coming back to Canada in December. Is this true?

There's really no way for me to answer this without getting into trouble. Pass.  [wink]

Thanks for the quick response. I understand.

Quick question for TylrC...If the Festool vacs (I have two, and three Feins) are so static sensitive, why does Festool sell hoses and attachments that are not antistatic??  It seems like an obvious contradition.

Good question [member=25351]rst[/member] .  We are confident that use of our Non-Antistatic hoses present no issues for our vacuums.  We design, produce, and test these, but can’t speak for competitive products. 

To bring things back to the OP question,  our CT units are “Fully HEPA Certified”.  This means that not only was the filter tested and certified, but the whole CT unit was actually tested, as it is supplied.  It was not tested for any 3rd party attachments, so the certificate only applies to the unit as delivered/supplied.

Hope this helps.

It is pretty hard to get air out the DD unless one is blowing air in.
If one is sucking through it the even if there are massive leaks it is all gong through the bag and filter in the end.
Maybe if one was sucking out an attic of Mr Fluffy, then go into the bag, rather shake out a DD full of asbestos... But for wood I cannot see much of an issue.

The physics doesn't challenge me .. my curiosity is the legalities ... Festool can't warrant that the same bag isn't deteriorating after 3 years constant use in a CT with a Dust Deputy connected - so where does that take the HEPA certification?

I think Tyler has provided the answer ... Thanks [wink]

I am sure a legal case could be managed to try and bring a suit against a company, and we have seen plenty of examples that boggle the mind.

I was thinking the other day that it is odd the Mrs car has a speedo that goes to 240 kph, and it is almost impossible to tell with any certainty if one is going 40 or 60 in those zones. You spend more time haunched ova looking at the dashboard rather than looking at the school kids crossing the road all with heads down like monks (texting).

Even though the highest limit is 130 khp (before no limit), someone would probably file a suit if the car did not have a 240 kph speedo.

I too am heartened that Tyler provided the statement.
