Oneida Ultimate Dust Deputy



A short while ago I moved into a 250 square foot shop, about 1/3rd the size of my former shop. As a result, I've had to rethink how I do my work. Because space is so precious I decided to forgo stationary machinery for more size-efficient benchtop machines, and to dispense with a conventional dust collector. I now use a Festool CT26E dust extractor to manage dust in the shop. While its been somewhat of an adjustment, I'm quite happy with the dust extractor. It does an excellent job of capturing most of the dust at source, it's quieter than a conventional dust collector, easy to move around the shop, and can be quickly switched from one benchtop machine or power tool to the next.

The major drawback that I found with a dust extractor is the frequency, and cost, of bag changing. The CT26 has a 6 gallon bag - when using a benchtop planer or jointer bags fill up rapidly, and at $5 per bag, the cost mounts fairly quickly. Of course, I could dispense with the bags altogether, and just empty the extractor when it fills up. This doesn't appeal to me, as my shop is windowless, and transferring the wood chips and dust into another container would inevitably result in dust getting back into the air. Plus, it would substantially reduce the life of the HEPA filter, and probably its effectiveness.

The solution has come in the form of Oneida's Ultimate Dust Deputy. The Dust Deputy converts any of the larger Festool dust extractors into cyclonic separators and increases dust storage capacity by 50% to 9 gallons (the Mini and Midi models may require some modification to accept the Dust Deputy). Plus, disposable dust bags for the Dust Deputy cost less than $1 each.

Oneida has a range of other Dust Deputy models for those who don't own a Festool dust extractor. Or, you can buy the individual components that make up a Dust Deputy to create your own customized system.

The Dust Deputy comes as a kit with three major components:

  • 9 gallon capacity storage container (holds the dust bag)
  • Cyclone separator (separates chips from fine dust and drops chips into the dust bag)
  • 6' of static dissipating hose (sends fine dust to the dust extractor)

Plus, you get some hardware to connect the components together, and three dust bags. It took me about 15 minutes to fully assemble the Dust Deputy.

Heavy duty container stands up to the rigors of shop use

The storage container is compact, measuring 11-1/2" by 15-1/2" by 14-1/2" high, and is made out of a static dissipating plastic which reduces the build-up of static electricity so that you don't get zapped if you touch the box when its in use. The walls are almost massive at just under 5/16" thick, making it extremely durable. You can stand on the box without breaking it.

Separator attached to container cover

The separator, made from the same type of static dissipating plastic as the container is roughly 6" in diameter and just under 14" high. You screw the separator to the container cover over a rubber gasket that provides an impermeable dust seal. With these two parts joined together the Dust Deputy measures about 28" high.

Lid gasket provides an air-tight seal

Oneida supplies an adhesive backed gasket that you apply around the lip of the container cover, which provides a tight seal between lid and container. The gasket is easy enough to apply, but make sure you read the instructions, as the gasket has to be placed on the underside of the lip, as shown in the photo above.
 

Rubber latches hold the lid firmly in place yet make for quick lid removal

You also get two rubber latches that you screw to the container - these secure the cover to the container. The handles make opening and closing the container quick and easy.

Adapters connect dust hose to the extractor

The kit also contains three plastic adapters and a 2-1/2" by 6' length of flexible hose. The straight adapter connects the Festool dust hose to the Dust Deputy. The two elbows connect the hose to the top of the cyclone and the intake port on the Festool extractor. Make sure that the elbow that has the 1/4" vacuum tubing attached to it (the elbow on the right in the photo above) is inserted into the Festool intake port. Insert the other end of the 1/4" tubing into the shut-off valve on the side of the storage container. The vacuum tubing will pressurize the inside of the storage container so that the dust bag doesn't compress when you turn the dust extractor on.

Metallic tape grounds the adapters

You need to attach a piece of metal tape to the inside of the adaptors to complete the grounding system. Oneida only provides 12" of the tape, just barely enough for the three connectors, so take your time and be careful not to muck things up. If things go awry you can use a strip of foil duct tape.

Filter keeps bag from being sucked into the valve

Make sure you install the small filter into the handle cavity inside the storage container. It prevents the dust bag from being sucked into the valve and also keeps dust out of the valve. If you ever use the Dust Deputy without a dust bag simply shut the valve by turning the valve handle so that it's not inline with the tubing.

The Dust Deputy securely attaches to the Festool like any Systainer

The Dust Deputy attaches to a Festool extractor just as any Systainer would, using the interlocking Sys-Dock feature. I find the system very secure, and you can quickly detach the two units.

The Dust Deputy attached to a Festool CT26

The Dust Deputy works by drawing wood chips and dust into the cyclone (via the green hose in the photo above). The design of the cyclone uses centrifugal force to spin the incoming debris, separating the lighter dust particles from the heavier chips. The chips fall through the cyclone into the storage container, while the fine dust is sucked into the Festool dust extractor (via the larger gray hose in the photo).

A nearly Festool Selfclean bag

A great advantage of the Dust Deputy is that it uses inexpensive .05mm plastic dust bags.which measure 30" by 36". The bags do seem thin, but so far I haven't had any problems with them. They provide 50% more storage capacity than the Festool Selfclean dust bags, and are 1/5th the cost. If you do a lot of planing or jointing, then you know how quickly the Festool bags can fill up. The cost savings can be significant.

Installing the bags is very quick, and because they're so large, they're easy to tie up once full. You can purchase the bags from Oneida, or use any equivalent plastic bag. There is no external gauge on the Dust Deputy that tells you when the bags is full. You can wait until you notice that debris isn't being picked up, or you can occasionally flip open the cover to check capacity.

What roughly 6 gallons of dust looks like

Oneida claims that approximately 99% of the debris ends up in the storage container, with only a minute amount ending up in the extractor.

Oneida_11

The same 6 gallons of debris in the Dust Deputy - and still lots of room left 

To see how much dust is diverted to the Dust Deputy, I vacuumed 6 gallons of dust without putting a dust bag in the Festool extractor. When I opened the extractor (photo below), there was barely any dust in the Festool. Virtually all the dust had been diverted to the Dust Deputy. I also checked the Festool HEPA filter - there wasn't much fine dust in it.

What ended up in the Festool - practically nothing

Oneida_15

Virtually no dust in the HEPA filter

I don't know how many plastic Dust Deputy bags I'll go through before I need to replace the Festool dust bag, but my guess is anywhere upwards of 100 bags. I've already filled nine Dust Deputy bags, and I can barely feel any dust in the Festool bag.

Not only will I realize a significant cost savings in Festool bags, but the HEPA filter, which retails for about $100, will last for ages before I need to replace it. And, I won't have to clean it very often.

Fits easily into an 18" wide space

I can also report no discernable loss of suction with the Dust Deputy attached to the Festool.

If you own a Festool CT dust extractor, and find that you're going through a lot of dust bags, then I highly recommend the Oneida Ultimate Dust Deputy. You'll realize a return on your investment at around the forty bag mark. Even if you don't own a Festool you might want to check out the other range of Dust Deputy models that are available. It's the quickest, easiest, and most cost efficient way to improve a vacuum-based dust collection system.
