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/festool-tools-accessories/which-pn-for-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.

@threesixright, 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.

@Garry, Thanks again Garry and what you say makes a lot of sense. I will watch the video properly tomorrow.

Steve
