Hi,

I bought the new MIDI (the one that comes with bluetooth) and the CT-VA-20. The CT-VA comes with a connecting tube (~ 90 cm), but has a angled adapter on both sides. The new MIDI moved the hose input (which is good, you gain a bit tube length) but you need a straight adapter (I think in the old MIDI the angled adapter worked fine).

The correct adapter is #500672 (Antistatic Rotating Adapter 32mm / 27mm)

Since it was unclear to me what adapter you need, I started this topic:http://festoolownersgroup.com/festo...r-rotating-hose-adapter-ct-va-20-on-ctl-midi-(new-model)/msg573493/#msg573493

Many thanks to GarryMartin for helping me out ( and correcting FT  [tongue] )!

As you can see on the pictures the tube is long enough to put it side by side or on top.

Hi there, very useful info, thanks for posting it up, and also to Garry, he certainly knows his Festuff.

Regarding the  CT-VA-20, I've just bought a couple of CTM 26 e AC's so we have a few of them now, I'm thinking of adding a separator to at least one of them, possibly a Dust Commander or similar etc but, have heard it can void warranties, so may go with the Festool official.

I just wondered how much suction is lost with these devices, probably not enough to cause issues but, I'd still be interested to know. Perhaps when you get using yours regularly, you might be able to post your thoughts?

Thanks again
Steve

Hi Steve,

I'm not near a pro.  I'm doing a rebuild of my house, and for that I like to use good tools. Nothing more annoying than stuff that doesn't work. And my health is something worth.

When I saw the CT-VA (especially the price tag), I was like: never in a million years! I also wanted to do a deputy, buy a cheap vac, etc. Then I thought a MIDI + deputy. But when I counted the work to get it doen, connectors, hose (AS!), etc. I'm almost ½ way. And then the utter frustration to get connections done right (jus searching for correct hoses and connectors,  [scared]).  I saw on youtube the VT-VA works well with the MIDI. The difference with the 26 is not that much. On top, you get a 20 L container and > 95% you can collect. Meaning your bags last 20x as long. So a bigger vac for just more volume makes no sense, unless it has a ton of more suction power. IMO the resale value is also something worth.

What I see now: it fits perfect, not unstable. The flow feels good. I will put it through the test in the months to come (routing, sawing, sanding, cleaning and even some wet-vac action). But I do have high exceptions (darn, now the only way is down :( )

I will post my findings at some time, however it will not be very soon (like days or weeks).

I needed to flip a mental switch (never thought I would spend this money on a vac system). Dust collection is not just a nice-to-have. It's the foundation of all you do. So spending some (extra) money, on the long run is a wise investment. Well at-least to me. I'm sure other vac's are great (Starmix, Bosch, etc.)... I just love the green train 😀

I know this might come across has a FT pitch, its not. I'm fairly new to FT. But simply love it.

I haven't done any tests myself yet, but I was straight away curious that they'd use a 32mm hose for the connection from cyclone to extractor which favours the use of a 27mm hose to the tool. As I'm sure you know, common practice says you decrease hose diameter the further away you get from the extractor so that you balance airflow/suction (one of the reasons for the performance improvement in the tapered hoses).

Having said that, the Wood Whisperer did do a video comparing the airflow speed drops.

The most important part of the video is probably the one where he mentions tool speeds. Obviously a 17% drop in air speed at the extractors top speed means that if you run your extractor normally at anything less than top speed, then you can compensate easily. And of course, we rarely run tools like sanders at full speed as the extraction is too powerful for them.

Swings and roundabouts I guess. I'll see how it goes in practice.
 
[member=65767]threesixright[/member], Thanks, and I agree with everything you’ve typed. Health is paramount whatever the cost. Also regarding the tools, pro or not, it’s nice to work with quality tools, and I’m a firm believer that we should buy the very best we can afford.

I hope you enjoy the projects and the tools.

Steve.

[member=1943]Garry[/member], Thanks again Garry and what you say makes a lot of sense. I will watch the video properly tomorrow.

Hi,

I created an account just so that I could thank you for posting this. This is exactly the info I was looking for.

So thanks!

Stephen.
 
Too bad he didn't test with the D36 hose since that is more likely to be hooked to a tool than the D50. Especially a tool that produces large / volume chips which is one of the things in which the cyclone is most useful (OF2200, HL850, etc).

For my own usage experience I have not found the suction to be lacking for the routers, 850 planer, kreg jig, or floor clean up when using the CT Separator. Yes, I am sure it measures less, but I have found it to still be enough. Running it on a CT33 (130cfm rating) with D36 hose except for the Kreg (D27).

Wider = less resistance. Wider end toward the extractor because the other way around... you get clogs.

The cyclone is relatively useless with sanders anyway  [huh]

I have my CT's on full speed except when sanding; then usually on the lowest speed, except when a part of the sander's pad isn't covered.
 
Any cyclone (with a static geometry) is optimized to work well at certain air volume/speed/pressure differential.

The CT-VA20 is clearly optimized in such a way it is still suitable for a sanding task with low air volume and low air speed in the cyclone.

I would actually say that at full tilt, with a short 36 hose, the cyclone is "overloaded", there is too high speed of the air and the efficiency is not all that great. But this is fine, as one would not use the big hose with a sander which generates the hardest to catch particles to begin with.

In my experience, with a TSC 55, the difference cyclone/no cyclone is approximately the same as 32/27 hose versus the 36 mm hose. If I use 32/27 hose with cyclone, there is a bit of a suction loss, but not much really. The small hose is already bottle-necking the vac so the cyclone just takes the reserve power which would otherwise be wasted.

In retrospect, I love the thing.

The most important feature is the clear dust canister. That is critical to make sure one empties it often-enough to avoid filling bags needlessly.
 
I am seriously considering getting the Festool Cyclone for my CT-26, but I'm just not sure about the vertical space required above the CT itself. I could put it in the Sysport cabinet that is next to it, I suppose, but it might need more hose? Have any of you had any experience with moving the cyclone away from the CT? A longer hose on the extractor itself doesn't seem to hurt it much, So it makes sense that it would be ok.
 
I'm thinking of sometimes pairing my CT-VA with a Midi or CT 15.  I understand the right angle hose connector won't work, and I have an extra length of 35mm hose on hand.  Does anyone see any issues using the 35mm hose between the extractor and the cyclone? 

I would assume not, but I could easily be overlooking something.
 
Ok - confused, but happy - I had purchased a new MT Midi I (BT) and the CT-VA-20 separator to go with it. The hose that came with the CT-VA-20 has one rt angle end and one straight end with a rotating connector on it. I had seen a YT video from Festool Australia that said it the CT-VA-20 came with both an angled end and a straight end for the Midi I. From what I read here, I assumed I'd be getting two angled ends, or maybe the extra end that the Australians get - what I got was a hose with an angled connector on one end and a straight one on the other end. It works just fine with the Midi I like this. I had even purchased a straight connector for it that I guess I'll be returning. Festool US has apparently changed something. Pic attached -

This has been my experience with a CT-MIDI-I and a CT-VA 20 as well.  I had no issues whatsoever hooking it up.  I set the CT-VA 20 on the top of my OG CT-MINI, but never tried to stretch the hose to the back corner of the MINI to see if it would reach.  The intake on the MIDI-I and MINI-I is much more user friendly with regards to the CT-VA 20.

This would imply the short hose coming with the CT-VA-20 would be 32/27 mm? That MIGHT not be the case at least in Finland, in my case the hose is definitely thicker:

- outer diameter is 40 mm.
- inner diameter is 32 mm.

In Finland the hose will come with two pieces of 90 degree angled connectors, which makes no sense (extra angles just restrict the airflow for no real benefit and excludes you using it with CTL MINI/MIDI). Ok, so the inner diameter IS actually smaller than I would have assumed, so the D32/27 DAG-AS/CTR might be the correct one after all.
- Link:https://www.festool.com/accessory/204919---d3227-dag-asctr

I have asked Festool support in Finland to confirm the correct part number for this case.

Has anyone trialed what impact a larger hose for this would mean in practice? I would have assumed the short hose from the vac to the cyclone should be as wide as possible to avoid restricting the airflow.
