DustHog SDC · Self Contained Shaker
DustHog SDC Self Contained Shaker Dust Collector
Your compressor is already working hard enough. The SDC cleans its filters with a high frequency shaker instead of compressed air, which takes an entire utility off the table and suits a process that runs in bursts rather than all shift.
Your SDC modules, filter inserts, and replacement parts ship from us anywhere in the country, with one stated price on your quote.
At a glance
No compressed air, and that is the whole argument
DustHog cleans this one with a high frequency, low amplitude oscillating mechanism that shakes the dust cake off the filters. There is no pulse valve, no manifold, no air line, and no draw on your compressor. On a shop where compressed air is already the bottleneck, that is not a small feature.
DustHog positions it for intermittent duty and for small floor space, and it is field expandable, so you add modules rather than replace the collector when the line grows.
The trade is that a shaker cleans between runs rather than continuously. That fits a process that stops. It does not fit one that never does.

The models
Nine sizes, and media area is what actually sizes it
DustHog gives each model a nominal airflow range rather than a single number, because the right point inside that range depends on your dust. Light, dry, free releasing dust sits toward the top. Heavy or fine dust sits toward the bottom, and buying the next size up is usually cheaper than living at the ceiling.
| Model | Media area | Nominal airflow range | Motor options |
|---|---|---|---|
| SDC-140 | 141 sq ft | 420 to 1,120 CFM | 2, 3 hp |
| SDC-210 | 211 sq ft | 630 to 1,680 CFM | 3, 5 hp |
| SDC-280 | 281 sq ft | 840 to 2,240 CFM | 3, 5, 7.5 hp |
| SDC-350 | 343 sq ft | 1,050 to 2,800 CFM | 3, 5, 7.5 hp |
| SDC-420 | 421 sq ft | 1,260 to 3,360 CFM | 5, 7.5, 10, 15 hp |
| SDC-560 | 562 sq ft | 1,680 to 4,480 CFM | 7.5, 10, 15, 20 hp |
| SDC-700 | 686 sq ft | 2,100 to 5,600 CFM | 15, 20, 25, 30 hp |
| SDC-840 | 843 sq ft | 2,520 to 6,720 CFM | 20, 25, 30 hp |
| SDC-1050 | 1,029 sq ft | 3,150 to 8,400 CFM | 25, 30 hp |
The model number is the media area. SDC-140 carries 141 square feet, SDC-1050 carries 1,029. Once you see that, the line reads itself, and you can work out roughly where your load lands before anyone opens a catalog. Weights across the nine run from about 710 to 2,265 lbs, and inlet connections are 8, 10, 12 or 14 inches depending on the model.
What you choose
The configuration set
DustHog builds the SDC to order from a published add-on list. These are the choices that change the machine rather than the paperwork.
| Choice | Options | What it changes |
|---|---|---|
| Size | SDC-140 through SDC-1050 | Media area, and therefore airflow |
| Filter media | Polyester sateen, twill, twill HO, PTFE membrane | Dust release, moisture tolerance, efficiency |
| Motor | 2 through 30 hp on 230-460/3/60 | Where in the airflow range you land |
| Discharge | 20 or 55 gallon drum, drum lid options, slide gates, drawer base | How often somebody empties it |
| Safety | Explosion vent (membrane), sprinkler connection points | Whether it can face a combustible dust |
| Controls | Motor starters, VFDs, Magnehelic gauge | How it starts and how you see filter loading |
| Air handling | Fans, dampers, silencers, slip or flanged inlet collars | How it ties into your duct |
| Access | Hopper access doors, extended leg set | Service reach and drum clearance |
The motor starter is the one people assume. DustHog’s catalog lists the SDC with the motor starter not included, and the owner’s manual expects a properly sized fused disconnect or circuit breaker to be installed to protect the equipment. Both are ordinary, and both are easier to price now than to discover at start-up. We put them on the quote by default and you can take them off.
Media and filtration
Four media, and the one that matters is the moisture answer
DustHog rates the SDC at removing up to 99% of dust by weight, and offers four media, all rated to a maximum of 275 degrees F.
| Media | DustHog’s description | Where it goes |
|---|---|---|
| Polyester sateen | Standard on all units. A good balance of efficiency and durability | General woodworking, plastics, paper dusts |
| Polyester twill | A smooth filter surface that enhances dust release | Agglomerated or fibrous dusts |
| Polyester twill HO | Hydro-oleophobic. Use where moisture or oils may be present | Damp processes and washdown areas |
| PTFE membrane | Exceptional efficiencies and excellent dust release | Chemical, food, industrial processing |
If there is any moisture in your dust, say so before the media gets picked. A shaker relies on the cake letting go when the filter moves, and damp dust does not let go. The twill HO exists for exactly that, and it costs far less than a set of filters that blind in four months.
Afterfilter assemblies are available on the SDC. DustHog packages them separately from the collector, so if your discharge returns to an occupied space, flag it early and it goes on the same order rather than turning up as a second purchase.
Cleaning and ownership
What a shaker actually asks of you
How it cleans
DustHog applies a high frequency, low amplitude shaking mechanism to the filters to dislodge the collected dust. Their own framing is that it removes the need for costly or noisy compressed air.
The shaker motor is a third of a horsepower on 230/460 three phase at 1,140 rpm, and DustHog’s manual calls for greasing it every 3,600 hours. That is close to the only recurring mechanical task on the machine.
What a shaker does not do is clean while it runs. It cleans between runs. That is why DustHog positions the SDC for intermittent duty, and it is the single fact that decides whether this is your collector.
What it costs to own
No compressed air is the headline. On a pulse jet collector the air is a real, permanent line on the utility bill, and it grows as the media loads. Here it is zero.
Against that, filters are the consumable and they are not small. DustHog notes filters can weigh in excess of 125 lbs, so a filter change is a two person job with a plan, not something somebody does alone on a Friday afternoon.
A Magnehelic gauge is on the option list and we recommend it every time. Without a differential pressure reading you are guessing at filter condition, and guessing is what turns a filter change into an unplanned shutdown.
Combustible dust
DustHog publishes explosion vents on this one, and that is a real starting point
The SDC is one of the DustHog bodies where a membrane explosion vent is an ordered configuration rather than a conversation. DustHog catalogs explosion vent versions of the collector under their own part numbers, and lists sprinkler connection points alongside them. DustHog’s wording is that sprinkler connections and explosion vents meeting NFPA standards ensure safe collection of combustible or explosive dusts.
What DustHog supplies and what you supply is worth being exact about. DustHog may factory install the sprinkler connection coupler. The sprinkler head and any related fire control devices are the buyer’s to supply, install and test. DustHog also states plainly that dust collectors do not contain fire extinguishing equipment unless specifically ordered.
Three things are not on DustHog’s published SDC option list at all: spark arrestors, explosion isolation, and abort dampers. Those come from the system design around the collector rather than from the collector order. DustHog’s own instruction on sparks is that system design should include methods to prevent sparks from entering the dust collector.
NFPA 660 took effect January 1, 2026 and consolidated NFPA 61, 484, 652, 654, 655, and 664. NFPA 68 for venting and NFPA 69 for explosion prevention remain separate referenced standards. Your dust hazard analysis has to be reviewed at least every five years and whenever the process changes. DustHog’s own manual says the same thing in their words: the owner or user is required to test their dust mixtures and to have record of a dust hazard analysis.
You get a design drawing you own and can take to your own engineers. For your DHA, go straight to DHA Report Group and request the intake form. The DHA itself is completed by you or by a qualified third party. We do not author it and we do not stamp drawings.
What it is built for
Industries and processes DustHog names
Ceramics, food processing, furniture, plastics, pulp and paper, rock and related products, rubber, and woodworking. DustHog also calls out technical, trade and vocational schools by name.
Processes: bin ventilation, buffing, grinding, mixing, packaging, polishing, sanding, and sawing.
The school listing is not marketing filler. A school shop is the textbook intermittent duty case: heavy use for a class period, then nothing, then heavy use again. That is exactly the duty cycle a shaker is built around, and it is why the SDC turns up so often in trade and vocational school work. It lands the same way in woodworking and cabinet shops and on food and supplement lines where the process runs in batches.
Fit check
When the SDC is not right for you
Your process never stops
A shaker cleans between runs. On a line that runs three shifts without a break, the filters never get a proper clean and the differential pressure climbs until somebody notices. DustHog positions this one for intermittent duty, and that is worth taking literally. Continuous duty is SFC territory.
Your dust hazard analysis calls for isolation
Explosion vents and sprinkler connection points are on DustHog’s list. Isolation devices, spark arrestors and abort dampers are not. If your DHA requires isolation, that is a separate line on the system drawing and it needs designing rather than ordering. Start on the combustible dust side.
Your dust is damp and nobody mentioned it
A shaker needs the cake to let go when the filter moves. Damp dust holds on. The hydro-oleophobic twill exists for this, but it has to be chosen at order time. When the job outgrows the SDC, a Scientific pulse jet baghouse takes it from there.
One bench is the whole problem
A collector and a hopper and a duct run is more machine than a single station needs. A downdraft table or a source capture arm costs a fraction of it.
Your contaminant is oil mist or coolant
Liquid aerosol blinds dry media fast, and a shaker will not shift it. That is mist collector work. See SmogHog mist collectors.
SDC questions
Does the SDC need compressed air?
No, and that is the main reason to choose it. DustHog cleans this collector with a high frequency, low amplitude shaking mechanism rather than a pulse jet, so there is no air line, no manifold, and no draw on your compressor.
How do I read the model number?
The number is the media area. SDC-140 carries 141 square feet, SDC-560 carries 562, SDC-1050 carries 1,029. Media area is what sizes the collector, so the model number is telling you the thing that actually matters.
Why does DustHog give an airflow range instead of a number?
Because the right point inside the range depends on your dust. Light, dry, free releasing dust sits toward the top of the range. Heavy or fine dust sits toward the bottom. We pick the point from your material rather than from the top of the table, and buying the next size up is usually cheaper than running at the ceiling.
Can it be expanded later?
Yes. DustHog builds it modular and field expandable, so adding capacity means adding modules rather than replacing the collector. Size the fan and the duct with that in mind and the expansion stays simple.
Can the SDC handle combustible dust?
DustHog catalogs explosion vent versions of the SDC under their own part numbers, and lists sprinkler connection points. That makes it a real starting point when your dust tested combustible. Spark arrestors, isolation and abort dampers are not on DustHog’s list and come from the system design. What you actually need is decided by your dust hazard analysis and lab testing of your material.
Is the motor starter included?
No. DustHog’s catalog lists the SDC with the motor starter not included, and the manual expects a properly sized fused disconnect or circuit breaker for protection. We put both on the quote so they are priced rather than discovered at start-up.
How heavy are the filters?
DustHog notes filters can weigh in excess of 125 lbs. Plan a filter change as a two person job. It is also the reason we recommend the Magnehelic gauge option, so the change happens when the pressure says so rather than when the collector stops keeping up.
