Oneida Air Systems Ultimate Dust Deputy SD Cyclone Separator for Festool CT Vacuums - 9 Gallon Systainer Kit

$300 is a lot to pay for something like this and I had to justify it but I’m glad I got it. It extracts all but the minuscule amount of the extremely fine micro dust that my CT26 grabs in the bag. I’ve gone through a full “basket” of collecting sander dust, domino chips and hose end cleanup on the bench and am very pleased with the performance. It fits the CT26 very solidly, doesn’t stifle suction at all and elevates the hose for bench work (I mainly us it in my shop). If I’m not buying expensive bags then I’m happy. I also don’t want to avoid general shop cleanup with my CT26 by thinking I’m just filling up an expensive bag and could do it another way. I bought the CT26 to do that job and many others to keep the air breathable and healthy as possible so why compromise. Overall it’s working great, just wish it would have been around the $200-$250 mark and I think it would be a no brainer for most to add to their cleaning arsenal.

I ordered this to put on a CT MIDI unit. There are several problems with installation. 1. The hose provided is not long enough for the MIDI. If the MIDI inlet was on the front of the machine the hose would work fine. But on the MIDI the inlet is under the Systainer area above the back wheels. The only way to route the hose is through an opening at the front, then all the way to above the back wheels. If the hose where 12-16" longer it would work fine. I had to find another hose I could order that was the right diameter and will have to custom cut the length. 2. The Oneida container will not lock into the Systainer clips. The two clips on the long side are able to lock but the pins on each end are not molded correctly and the clips will not lock on. This is a major issue because the Oneida unit will NOT stay in place. If there is the slightest tug on a hose the Oneida box just slides off the CT MIDI. I have a Systainer that is able to clip and lock in place just fine. So I believe this is an Oneida mold problem during manufacturing. This is completely unacceptable from a company like Oneida. I have not had contact yet with Oneida to find a fix for item 2 but, when I do, I will update this review. UPDATE: Heard back from Oneida. I must say I am very disappointed. I found out that Oneida has known about this problem for a couple of years but, has failed to modify the design of the product. Oneida's solution to the problem is for me to modify the unit by grinding away the plastic that is in the way. In my opinion an end user should not have to make modifications to a brand new product when using that product as expected.

Arrived on time and in good condition. Set up was easy, especially after watching a third party video online. No noticiable degradation of the draw with the Dust Deputy. The only modification I had to make was adding a wye to my 2" PVC boom arm above MFT table height as the Dust Deputy adds about two feet to the height of the CT26 and the hose at the inlet of the Deputy would have to be routed down and then back up through the PVC, causing me to lose 2" of hose at the tool end. Overall, a great, well made product that is a little pricey (like what with a "Festool" related product isn't), but it will save me a small fortune in bag replacement in the CT.

Still with static which I thought they were supposed to have fixed. This thing gives you heart palpitations it's so bad. When it wipes out my stupid expensive vac I'll go dump it in their parking lot since they're 8 feet from my house.

This is a fantastic item for a small shop. It definitely works well and saves a LOT of dust from your bags. On the flip side, I purchased this for our CT Mini and I have not managed to get it to lock in place on top. The best I can do is get it stable, but one bump and it comes loose. I do with the hose that came with it were about 6" longer as well, but it does make the bend, so I can't complain too much about that. My hose that came with the CT Mini fit on the dust deputy perfectly, which was a relief because I've heard some people have issues there. I guess I got lucky with the hose I had! It was definitely worth the money, just wish it fit my particular unit better.
