Here is my current dust collection setup.  I am using a 50mm hose from a CT33 to a Kapex.  This requires use of a Festool adapter which fits inside the Kapex dust port.  In other words diameter is restricted to 27mm at that point.  I am not sure if this setup gives more airflow compared to a 36mm hose which fits outside the Kapex dust port.  Nevertheless, it can be done.

hi cort.

i use a 36mm hose.
the rubber end fits snuggly over the kapex dust port.

i would like to hear your experience with using the 50mm hose as i was always recommended the 36mm hose.

you could buy the adaptor which would allow you to fit over the dust port and not inside it.
i dont know the model no. but i am sure i have seen one in the festool catalogue.

regards, justin.

I am not so sure that Festool offers a reducing sleeve for the D50.  To be clear, the reducing sleeve is the fitting at the tool end, while the rotating connector is the fitting that fits into either your extractor or a connector sleeve.  The Festool USA site shows D50 hoses with both rotating connectors and reducing sleeves, and the description states that the D50 hoses come equipped with one of each of these fittings.  But the page of reducing sleeves does not include one for the D50 hose.  Furthermore, I have a D50 hose (other than the one that comes with the Boom Arm) that came with rotating connectors on both ends.  I suspect that the pages for the D50 hoses are unedited copies of one of the D36 hoses and therefore both the photo and description are not correct.  The non-antistatic hose reducer that is shown connected to the Kapex dust port in the OP looks to be the only option -- if I this is not correct, please let me know.

I would prefer to connect with a reducer that goes over the Kapex dust port rather than inside it.  However, I am not aware such adapter is available in the U.S.  Perhaps such adapter exists from a different manufacturer.  If anyone knows, please post.

As I understand things, all the above is correct. I believe that the 50mm hose is supplied with identical connectors (ie the Rotating connector) at both ends, despite what may be in the catalogue. This is confirmed by the Technical Note How to connect two hoses which says "The 50mm Festool hose has a 2 1/4" inch coupler on each end".

As Festool doesn't seem to market a 36mm Reducing Sleeve for the tool end of a 50mm hose, then an option would be to connect a 36mm hose to the 50mm hose (using the method shown in the Technical Note) and then attach the tool end of the 36mm hose over the Kapex dust port.

It would also be possible to cut a standard 36mm hose down to a foot or two.

Note that the same Technical Note points out that the funnel-shaped adapter is not Anti-Static...

"The #452897 Suction adapter is the funnel shaped open tube, the small end of which can be inserted directly into the tool tip of the D36 hose and will provide a 2 1/4" opening for any other hose. However, this piece is not made of conductive material, and for antistatic use, a piece of foil or conductive wire could be used to bridge across the junction."

Consequently the arrangement shown in cort's photo of hisKapex will not have anti-static properties, even though the hose is an anti-static one.

You could get the sleeve adapter (493047) and a short D36 hose from Festool Junkie (Festool D36 Hose AS 7 Footer (7 Foot D36 A) = $65.00)
That would allow you to connect the rotating ends and have a 36mm adapter that goes on the outside the Kapex port...

Dunno if that solution is worth $80, but there ya go...
 
Cort, I picked up the #452897 Suction adapter (funnel shaped adapter) about a month ago for this same reason. I've found myself on the job wanting my D36 hose for routing, clean up and so, not wanting to have to keep removing the hose for the Kapex I thought this would be a better solution.

For those keeping score at home, this isn't right. The small end of the #452897 is too small to fit correctly into the D36's tool end. Unless I'm misunderstanding something here.

Well, unlike you, I don't have the adapter, nor even a 36mm hose, but David McGibbon of Festool Tech Support, who wrote the Technical Note, seems to think they fit.

Here's the photo and accompanying text from the Tech Note:

[attachimg=#]

Since the adapter is called in the UK "Extraction adapter D 50/D 36 AA", and the Festool USA website describes it as "Non-antistatic hose reducer. For reducing from 50mm to 36mm hose", if it doesn't fit a 36mm hose, then something very odd is going on.

If you've got them sitting there, what is the outer diameter of the small end of the funnel adapter, and what is the inside diameter of the tool end of the 36mm hose?

The adapter to which I referred in my original post of this thread is indeed model 452897.  It fits inside the 36mm port on the Kapex.  Does anyone know if the fitting and housing on the Kapex have antistatic properties?

Post modified to reflect correct model number.

Forrest, my D36 hose is at a job so I don't have it handy but I do have the 452897 funnel adapter in front of me. It has a 34 mm OD (the same as the tool end D27 hose) that's why it fits inside of the Kapex's housing. Given the fact that the D36 fits on the outside of the Kapex housing that would mean the 452897 funnel adapter is smaller and won't fit. Plus, I've tried it and it definitely doesn't fit tightly. I have to say I'm surprised David would make this mistake. Perhaps the dimensions of the 452897 funnel adapter have changed.

EDIT: See Crowin's post #11.

That's a good question. (BTW, you've got the wrong model in this post, it should read 452897.)
 
i was reading through the festool catalogue last night and discovered the same little mistake.

why would festool advertise the extraction adapter 452 897 as 50mm/36mm if 36mm is the outside dimension?

Festool did not make a mistake in this case.  Neither did David.  But Brice did.   :o

The small end of the hose reducer does fit into the tool end of a D36 hose.  Yes, it is smaller than the rubber portion of the D36's tool end fitting, but if you push really hard the hose reducer will fit very tightly.  It fits into either the hose itself or a portion of the fitting further in -- hard to tell which.

So, the only mistake Festool made was to not make the hose reducer out of the anti-static material.  I've found that the copper tape used to repel slugs (available at most garden departments) works great in to complete the AS connection is many cases -- don't know how well it would work on these hose reducer fittings.

And Brice, next time put some muscle into it!       [wink]

The option Forrest describes looks to be the best option.  One connecting sleeve and a shortened D36 hose.

Corwin, I'm willing to take your word for it. However, my D36 hose is well used and the tool end is a bit stretched out so I don't know forcing it on will work (I did try to push it on but I don't remember how hard I tried). In other words, I think it's such loose fit I can't see it working on my hose.

All the same, I'm sorry for any confusion my comments have created. 
 
Well, it does fit into the tool end of the D36 so loose that one would just think it didn't have a chance and it was way too small to fit.  I seemed that way too  when I first tried, but a good shove and the reducer seats further up -- probably fitting into the inside of the hose.  So it shouldn't be an issue of your tool end wearing.  Err, uh, tell me I didn't just type that...  [embarassed]

Okay, round two with the 452897 funnel adapter and the D36 hose: It doesn't fit! (I should know better than to second guess myself :P) I brought my vac and D36 home from a job yesterday so I thought I'd make this work out following Corwin's advice and just shove it into the hose end. It really didn't seem like it was going to fit but I carried on, bad idea. The inner plastic piece of the tool end cracked, only then would the 452897 funnel adapter fit into the D36 hose. So I stand by my earlier statement, it doesn't work.   
 
Brice, sorry you damaged your D36 tool end fitting attempting to get the hose reducer to fit.  I didn't have this problem, as mine does fit.  Wonder what is different -- maybe your D36 hose has backed out of the fitting a little such that the hose reducer cannot reach the hose. 

If you PM me with your address, I'll send you another D36 hose end.

 
Do your building regs allow you to use that pink "rockwool" like insulation between studs... In the UK we should be using Celotex. I also tend to use 12.5mm celotex over the battens as well, then plasterboard ontop of this. You can actually feel your walls warm - or cold - depending on which you require !!

I've just done an outside office 50mm celotex between battens and 12.5mm over. Lovely and warm just with a small electric (oil filled) rad. very cheap to keep warm - cool in the winter....

Paul.

sorry, not festool related !

No, in the first picture in this thread. In the background, their is insulation between the studs - or i guess it is. It was in relation to the insulation.
