Steel Super Dust Deputy 5" Cyclone

93% of 100
For industrial use with single stage dust collectors and 4" to 6" piping, this steel DIY cyclone eliminates filter clogging, suction loss, and messy dust bags by removing over 99% of fine dust and debris from the airstream, containing it safely in a customer supplied container.

Build Your Own Industrial Cyclonic Dust Collector!

Single-stage dust collectors are great for small, hobbyist shops but they come with a cost & fine dust quickly clogs the filter, reducing suction and leaving your tools as messy as ever! Worse still, there's nothing to protect your dust collector 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!

Frequently Asked Questions
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.

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 else do I need besides the cyclone?

In addition to the cyclone and your dust collector, you will need a reinforced, airtight container to mount it to, as well as flex hose 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

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

The inlet of our Steel Super Dust Deputy cyclone measures 5" on the inner diameter to accept crimped steel ducting. It also includes a pre-crimped steel coupler fitting which can be used to readily accept flex hose or steel ducting on the inlet.

Can I use this 5" steel cyclone with 6" piping?

Yes, but this could add unnecessary air resistance to your layout and hinder your overall dust collection performance. For 6" ducting runs and industrial applications we recommend our C-650 cyclone instead.

Why should I choose the metal version of your Dust Deputy cyclone?

The Industrial Steel Dust Deputy is built for the toughest applications. If you're going to be sucking up large amounts of highly abrasive materials such as metals and gravel, the heavy-gauge cold-rolled steel cyclone will perform better and longer than our injection molded models.It's also ideal if you're expecting to suck up high-temperature materials such as hot coals and ash.

What dust collectors is the 5" Super Dust Deputy compatible with?

The 5" SDD cyclone can be used to retrofit nearly make or model dust collector with a 4"-6" 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.We recommend an operating airflow of at least 350 CFM for the 5" cyclone to effectively separate 99% of debris from the airstream.

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.

Do your steel cyclones have the same separation performance as your resin models?

Yes! Both our molded and steel Dust Deputy Cyclones use the same patented design to pre-separate dust and debris, protecting your vacuum filter from clogs and suction loss. The only difference between the cyclones is their durability. Steel cyclones are ideal for industrial applications with abrasive materials such as blasting sodas, glass beads, silica dust, etc.

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.

How do I install the cyclone onto my container?

Our Super Dust Deputy cyclone includes basic hardware and a foam gasket for mounting to your container's lid. We also offer a complete 17 gal. drum kit that can be readily used with any Super Dust Deputy cyclone. If you are supplying your own container, we provide this free downloadable Lid Hole Template for our customers. If you are connecting your cyclone to the dust bin via flex hose, you may also need a 6" Angle Ring Flange.

Does the Super Dust Deputy perform differently if it is mounted directly to a container vs. having a vertical hose/pipe between the bottom discharge port and the top of the container?

You will not see a difference in separation or airflow performance with either method. Users can choose either "mounting" method to position the cyclone in a way that works best for their shop.

The main factor you'll want to consider is how you'll be emptying the dust bin once it's full. Connecting the bin with hose allows the drum lid to be removed easier compared to lifting off the cyclone and lid together as a single component. The downside to the hose connection method is that you'll require additional components to purchase and will have more variables to consider when ensuring that the system is sealed airtight.

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.

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.

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.

Can I use this steel cyclone with smoldering or abrasive debris?

Yes, absolutely. This cyclone is built with heavy-gauge, powder coated steel for industrial applications collecting highly abrasive or smoldering materials e.g. hot ash/soot, blasting powders, concrete, grinding dust, etc. Please note that you should also ensure that your vacuum/dust collector is rated to accept these same types of materials i.e. do not collect hot/smoldering materials if your vacuum isn't normally capable of collecting this type of waste.

Can I use this Super Dust Deputy 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.

What can I use to mobilize my dust collection setup?

If you're looking for any easy way to move your cyclone around the shop, without having to lift and carry it every time, we recommend pairing the cyclone with our Universal Drum Dolly and our Angle Brace Kit (to add extra stability).

Is the steel cyclone rust-proof?

In short, no. The steel cyclone has a powder-coat finish, ensuring that it's durable and rust resistant, but if you expect to have your cyclone exposed to water on a regular basis (e.g. exposed to harsh weather, submerged in water, etc.) we recommend you find additional covering to prevent corrosion over time.
