Super Dust Deputy Deluxe Distributors:

Upgrade Your Tired, Old Dust Collector and Say Goodbye to Clogged Filters!

Single-stage dust collectors are great for small, hobbyist shops but they come with a cost; fine dusts can quickly clog the filter, reducing suction and leaving your tools as messy as ever! Worse still, there's nothing to protect your dust collector's impeller from being damaged should you accidentally suck up large wood chunks, bolts, etc.

How do you stop losing valuable time and money on maintenance and replacement parts? Install our cyclone!

Oneida Air Systems' patented Super Dust Deputy cyclone separates over 99% of dust and debris from the incoming airstream, virtually eliminating filter clogging, suction loss, and significantly prolonging the lifespan of your filter.

Frequently Asked Questions
Can I vent my system outside?

If you have conditioned air in your shop, (Heat or cool) then exhausting outside can be costly. If your building is small and well-sealed, you can interfere with flue exhausts as well. Close neighbors might object. If the Dust Collection system is run intermittently it is generally not a problem. Most buildings have enough leaks and crevices where the aforementioned volume of air does not cause problems. If you have a problem opening or closing an outside door when the DC is running, crack a window slightly. The rule of thumb is for every 500 CFM have at least 1 sq/ft of return air coming back into the shop. A lot of our customers blow exhaust air outside successfully.

Which Super Dust Deputy cyclone do I need?

If your shop has fixed piping that matches the diameter of your dust collector's intake, choose a cyclone that matches that as well. So 6" ducting connected to a dust collector with a 6" inlet should use our 6" XL cyclone. The same applies for 4" ducting runs and our new 4" Deluxe cyclone. If your shop has piping that is smaller than your dust collector's inlet, such as 4" piping with a 6" inlet, then our 5" cyclone can be used to transition between them. You will need reducers to complete your setup. If you have industrial applications, such as collecting hot ash/soot or highly abrasive materials such as blasting powders, you should choose our Steel Super Dust Deputy.

What dust bins should I use with this cyclone?

The shape and size of your container are completely up to you, so use whatever works best for your shop! A smaller container will need to be emptied more often, so most customers use at least a 17 gallon container with our Super Dust Deputy cyclones. Browse Dust Containers Any container you use must be: Airtight: Any air leaks can significantly reduce your suction and separation performance. We recommend foam gaskets or silicone caulk to provide an airtight seal. Reinforced: Light duty containers, such as typical plastic or aluminum trash bins, are not designed to withstand any suction pressure, and can collapse if used with a dust collector and cyclone.

The Super Dust Deputy 4 inch Deluxe comes with a 15 Gal. fiber drum. I have searched your website but have not found a model number for the 15 gal drum. It looks like you do not sell the 15 gal drum separately. Why not? I may want to buy a spare 15 gal drum.

The 15 gallon drum is a part of a kit, we do not sell this separately. We only stock enough to make the entire kit.

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.

What else do I need to get started?

This Deluxe kit includes the essential components, but you will still need flex hose and/or piping to connect it to your tools and dust collector. Any connections should be sealed using silicone caulk or HVAC foil tape.Shop for Assembly Tools

Do I still need to use my filter?

Yes. All of our cyclone separators are designed to be used in conjunction with an air filter as they are only meant to remove the majority of dust and debris - not all of it. Eliminating the filter entirely would allow small, harmful dust back into your shop's air.The exception to this rule is if you have the means to vent your waste air outside of the shop. If you pursue that method be sure to consider the loss of conditioned/heated air, local safety codes, and whether your neighbors will be affected by dust laden air.

Why do I need a cyclone separator?

Standard single-stage or bag-style dust collectors lose suction very quickly as the filter becomes clogged with fine dust. The cyclone uses centrifugal force to separate dust and debris from the incoming airstream, containing it safely away from the collector.This frees up the dust collector to move as much air as physically possible without hindrance. That means less downtime for filter cleaning, continuously high suction, and significantly prolonged filter life.

What filter works best with this cyclone?

We recommend that customers use our MERV 16± HEPA Filter Upgrade Kit as it provides the healthiest return air for your shop, as well as being easily serviceable thanks to its wide spaced pleating and non-stick membrane coating.

What dust collectors is the 4" Super Dust Deputy compatible with?

The Super Dust Deputy Deluxe cyclone can be used to retrofit nearly make or model dust collector with a 4" diameter intake. This inlet size is typical of 1/2HP to 3HP single stage dust collectors by manufacturers such as Delta, Harbor Freight, Grizzly, Jet, Laguna, Powermatic, Rikon, Rockler, Shop Fox, etc.For larger sized systems check out our XL cyclone instead.

How do I connect the 4" Super Dust Deputy to my tools?

The ports of our Super Dust Deputy Deluxe cyclone measures 4" on the outer diameter as many customers typically connect 4" flex hose directly to the cyclone. Our Hose Quick Connect Kits are also very useful in this regard.

Can I use this cyclone with food products?

While some customers have found use for our cyclones in food related applications (e.g. farming, coffee roasting, etc.) it is not rated as a food safe material by the FDA. This cyclone should only be used for food waste products and not anything that will re-purposed for later consumption.

Can I use this 4" cyclone with 6" piping?

No. For 6" ducting runs we highly recommend our Super Dust Deputy XL cyclone instead.

Can I use this with a shop vacuum?

No. Super Dust Deputy cyclones are designed for use in systems with high airflow volume (above 350 CFM) and low static pressure (below 10" WC). Shop vacuums are the exact opposite of this i.e. they are low airflow (below 250 CFM) but with high air pressure (above 60" WC). For standard vacuums we recommend our regular Dust Deputy kits.

What is the collection efficiency for the 4" Super Dust Deputy on wood particulates less than 10 microns? I don't see any information regarding this. Thank you.

We do not measure that small of micron with cyclonic separation. It will filter 99% of all visible dust/chips from the airstream.

Will this replace a hanging air cleaner.

Our system virtually makes the need for your hanging air cleaner obsolete. By using your single stage collector hooked up to the 4" Super Dust Deputy you will get the best dust collection, right at the source!

Can you explain this California Proposition Black Carbon warning? Cancer?

By California law, Oneida Air Systems is required to provide advance notice to customers of potentially hazardous materials included in our products. This requirement is enforced regardless of how much of that material is present in the actual product.

The black, static dissipative resin used to create this cyclone separator contains carbon black, which is a chemical considered as "possibly carcinogenic to humans" (Group 2B) when the chemical is an airborne, particulate form. This form would not be typical of normal use of the cyclone, but the law requires this statement be provided regardless.

Did you find what you were looking for?

  Proposition 65. California requires the following notice: WARNING: This product may expose you to chemicals, including carbon black, which are known to the State of California to cause cancer or birth defects or reproductive harm. For more information, visit
