Title: Cyclone dustcollection
Post by: Woodworkingnut on January 19, 2020, 05:37 PM
Seven years ago I submitted a post on building a cyclone dust collector for my Festool  vacuum. It still serves me well. I have found a few things that I think will improve its function for me. So back to the drawing board for the big vacuum. Keeping with my Festool obsession I have over the years added two more Festool vacuums to my shop. Large, medium, and mini, The medium vacuum has a cyclone attached to a beverage systainer that I purchased at Woodcraft for 50% off. The mini has a cyclone attached ,but seems too tall to me. So I have built another version which is more compact. Unfortunately I have discovered this version has lowered the CFM. I have built another version that while compact brings my CFM back up to where it should be. This new design can be used on the larger vacuums with good results. I would like to see what others have done , but don't know where on this forum to find them. If you can assist me please send me a message.

jigs and tool enhancement section is probably where you will find this stuff. did you try the search function.
i posted this a while ago showing video of my cyclone mod to a ctl midi. im sure there are plenty others too.

  Welcome back!

     You probably are aware but just to make sure .....................  Festool now offers a Systainercentric cyclone (or whatever anyone's personal technical term may be) unit.

I’m in the process of building a cyclone completely enclosed in Systainers. Like you I used a Systainer with the “thermal insert”. Same as the cooler box but the one I’m using is a Sys 3 box to save on space. I’m using the Static Dissipative Dust Deputy (black version) enclosed in a Sys 4 that sits on top of the Sys 3 with the EEP thermal box insert. The two Systainers have a round hole cut in them that allows the Dust Deputy to drop down. In order to fit the Dust Deputy in the Sys 4 it has to drop partway into the thermal insert lid area. I’ll attach pictures when I’m done to illustrate this better.

I designed and built a pre-separator that mounts on a Festool dust collector and that can be built for about $60.  However, Festool, which owns the FOG site, considers it to be a “competitive” product, so I cannot post any information about it on the FOG.

You should take a look at the ShopHacks site.  That guy does a lot of testing on his builds and has come up with what he says is a super effective cyclone design that you can actually incorporate a filter into.  He says it’s about a 15.00 build.

Reply for Rusty ...

I made one like this about 4 or 5 years ago. From experience, as you discovered, the paint tin needs to be strong enough to withstand the forces of suction.



The machine here is a Festool CT26E.

With Festool, you need anti-static, and the Dust Commander cyclone (on eBay) is made of anti-static material, but so are the hoses and all the fittings. It does not help to some and not all.

The other difference is that I use a smaller Festool systainer. The paint tin is attached to this. This arrangement has two advantages. Firstly, it is quicker to build and a sure fit   :)   and the second, the inside is a useful container ...

This is where the transformer for a Mirka sander lives. One could also keep hose attachments in there ...

@derekcohen  Is the paint tin permanently attached to the systainer lid? Or can you remove the tin to empty? Cheers

The paint tin is bolted to the systainer. To empty, the systainer is unclipped, and the combination carried away (The systainer - originally for a C12 drill) is compact, so this is not an issue).

I guess what I found was 1000 ways to get the same job done. I put a video on youtube titled Festool Dust Collectors with a Cyclone. saw some ideas that I want to incorporate in mine. Like I mentioned previously I have three a CT 33, CT 26, and Mini. I think I can justify having so many, not really but.... each one has a different purpose and because of that I have built three different cyclone setups.
