Tired Of Buying Expensive Filters & Dust Bags?

Dust extractors owners, particularly tradesmen and contractors, are well aware of the cost of replacement vacuum parts. No matter if you're woodworking, drywalling, or renovating, a clogged filter can cost you valuable time and money; both on the job-site and in the store.

With Oneida Air Systems' Ultimate Dust Deputy® (UDD) cyclone, you can convert your wet/dry vacuum into a seamless three-stage dust extraction system. Our patented cyclone design removes over 99% of airborne dust and debris, containing it in an easy to empty dust bin, before it ever reaches the filter. By pre-separating both the larger debris and the finer dust particles, the UDD virtually eliminates filter clogging and suction loss, allowing your vacuum to operate at maximum efficiency at all times and saving you money on expensive replacements!

  • Industrial static conductive Dust Deputy cyclone separator
  • Lightweight 9 Gallon dust bin with integrated carry handles features T-Loc Systainer ports that installs directly onto Festool® CT Dust Extractors *
  • Plastic liner bag retainer system allows for easy waste disposal. Just tie the bag off and toss it out - no more messy dust clouds!
  • 2" x 5' static conductive vacuum connection hose with 90° elbow adapter preserves grounding pathway

*Due to it's size, the UDD will protrude slightly when installed on CT Mini and CT Midi vacuums. Additional measures may be needed to mount the cyclone kit.

Maintaining The Static Grounding Pathway

Static is an inherent problem when you combine wood dust, plastics, and friction. That's why we've designed the Ultimate Dust Deputy using static conductive and static dissipative components; ensuring that it maintains a continuous grounding path from the tool to the vacuum's grounded inlet when used with anti-static tool hoses.

Frequently Asked Questions
Can I use this cyclone with smoldering or abrasive debris?

No. This cyclone is designed for use with light debris such as wood dust. For heavy-duty applications with highly abrasive or smoldering materials, we recommend our steel, Heavy-Duty Dust Deputy kits instead.

Does the Dust Deputy work with the new Festool CT units that have the T-Loc system to hold the systainer???

Yes! The Ultimate Dust Deputy is adaptable to all Midi and Mini Festool vacs. The new vacs do require you to rotate the systainer box 180 degrees.

Is it possible to just buy just the waste bin? I I have purchased the ultimate dust deputy, however in transport the waste bin was broken. I really don't want to purchase the whole system again and was wondering if you could purchase replacement parts?

Yes you can! SDS090000 is the part number, you would need to call into the sales line to place this order 1-800-732-4065.
