DustHog SCB · Ceiling Mounted Source Capture Cartridge Collector
DustHog SCB Ceiling Mounted Source Capture Dust Collector
You want capture at the arc, and you have no floor to give up. The SCB puts the collector overhead and drops two counterbalanced arms down onto the work, so the fume gets caught where it starts and the bay stays walkable.
Your SCB unit, extraction arms, ProTura cartridges, motor starter and replacement parts come through an authorized Parker distributor, priced off the factory list and shipped anywhere in the country.
Parker rates the SCB for non combustible dry dust. That is Parker’s own application field, not a caveat we are adding. If your dust is combustible, a ceiling hung collector that recirculates into the room is the wrong shape of answer and the conversation moves to an engineered system. More on that below.
At a glance
Source capture for the shop that has stations but no floor space
Catching fume at the source is always better than filtering the room it ended up in. It takes less air, less energy, and it keeps the contaminant out of the breathing zone instead of pulling it past it. The catch is that a floor mounted collector plus arms takes floor, and on a lot of shops the floor is already spoken for.
The SCB answers that by going up. Parker mounts the collector above the plant floor and runs two 8 in. counterbalanced arms down to the work, or lands 6 or 8 in. flexible or rigid duct on inlet collars instead. Filtered air recirculates back into the plant, so there is no roof penetration and no makeup air bill.
Two arms is the honest limit. It is a two station machine at 2,000 CFM, which suits a weld bay, a pair of benches, or a training room laid out in pairs. If you have eight stations, you are looking at more than one unit or at a different machine.

The models
Three builds, and the difference is which way the clean air leaves
Parker publishes three orderable SCB builds. Same collector, same 2,000 CFM, same 3.0 hp motor. What changes is the discharge side, which is a decision about how air moves through your building rather than a performance one.
| Part number | Discharge | Airflow | Motor | Current | Supply |
|---|---|---|---|---|---|
| 01-10077-0001 | Rear | 2,000 CFM | 3.0 hp | 4.8 to 9.6 A | 230 to 460V / 3 ph |
| 01-10077-0001L | Left | 2,000 CFM | 3.0 hp | 4.8 to 9.6 A | 230 to 460V / 3 ph |
| 01-10077-0001R | Right | 2,000 CFM | 3.0 hp | 4.8 to 9.6 A | 230 to 460V / 3 ph |
What 2,000 CFM means at the hood. That is the total the collector moves across both arms, so roughly 1,000 CFM at each hood when both are working. On mild steel MIG at a bench that is real capture as long as the hood is kept within about a foot of the arc. On heavier processes, or with the hood parked three feet back, it is not, and no collector fixes an operator who leaves the arm where it was yesterday. Hood discipline is part of this system working.
Footprint and hanging weight. Parker publishes the SCB at 98 in. deep, 45 in. wide and 39.625 in. high, weighing 775 lbs before arms and cartridges. That load goes into your roof structure or onto hangers, so the structural check comes before the purchase order rather than after it. Powder coated mild steel in Hog Gray.
What you choose
Five decisions, and the arm length is the one people get wrong
The collector is settled at 2,000 CFM. What you configure is how the air gets to it, what the cartridges are made of, and how the unit gets its power.
| Choice | Options | What it changes |
|---|---|---|
| Inlet arrangement | Two 8 in. counterbalanced extraction arms, or inlet collars | Whether operators reposition the hood or you hard duct to fixed points |
| Arm length | 7 ft, 10 ft or 12 ft | How much of the station one arm actually reaches |
| Duct connection | 6 or 8 in. flexible or rigid duct on collars | How a fixed hood or an enclosure ties in |
| Filter cartridges | ProTura nanofiber, or ProTura nanofiber fire retardant | Efficiency, cartridge life, behavior around hot particulate |
| Motor starter and supply | External starter, 230 or 460 volt three phase | How the unit is started and protected, and the feeder your electrician runs |
Measure the reach before you pick the arm. A 7 ft arm off a ceiling unit sounds like plenty until you account for the mounting height and the fact that the hood has to sit within about a foot of the work to do anything. Longer arms cost more and add pressure loss, and an arm that cannot reach the far end of the bench gets left parked and stops being a capture device. We lay out the mounting height and the arm reach against your actual station layout before the order.
Arms or collars is a real fork. Arms are the answer when a person moves the hood to the work. Inlet collars and duct are the answer when the capture point is fixed: a cutting table, an enclosure, a downdraft slot. Both are Parker configurations of the same machine, and the difference in what you get out of it is much bigger than the difference in price.
Cartridges and starter are their own lines. Parker orders the filter cartridges and the motor starter separately, and that is deliberate on the media side: weld fume, grinding dust and nuisance dust do not want the same cartridge. We put both on the quote by part number alongside the unit so what arrives is a working system rather than a cabinet and two arms.
Media and filtration
ProTura nanofiber, and what recirculating air asks of it
Parker fits the SCB with ProTura nanofiber cartridges, in a standard or a fire retardant build. Nanofiber media holds the dust cake on the surface instead of letting it drive into the depth of the media, which is what lets a cartridge pulse clean and come back near its starting pressure drop instead of climbing a little further every week.
On a source capture unit that recirculates, the media is the last thing between the arc and the air your people breathe for the rest of the shift. There is no stack to send a miss out through, which is exactly why the afterthought version of this decision costs more than the careful one.
Fire retardant media is the version to specify where hot particulate can reach the filter, which on a weld or plasma station with a short duct run is a live question. It is not a substitute for a spark arrestor, and we will say so rather than let FR media do work it was not designed for.
At 0.78 SCFM per pulse, a collector that pulses more often than it needs is quietly spending compressor horsepower all shift. Media that releases its cake cleanly is a compressed air decision as much as a filtration one.
Cleaning and ownership
Continuous cleaning, and what it needs to keep working
What the collector needs from you
Compressed air for pulsing, at 0.78 SCFM per pulse, and it has to be clean and dry. Air carrying moisture or compressor oil turns cartridge dust into mud, and a collector fed wet air fails in a way that looks exactly like a filter problem and is not.
If your compressed air system does not already have proper drying and filtration at the point of use, that is part of this project rather than a separate one, and it goes on the quote instead of surfacing after startup.
What service looks like on a ceiling unit
Everything you have to touch is overhead. Cartridge changes, dust removal and the annual look at the pulse valves all need safe access, which usually means a lift or a permanent platform. The arms themselves are reachable from the floor, which is the part that gets handled most.
Plan the overhead access before the unit goes up. A collector that is inconvenient to service gets serviced late, and late cartridge changes cost you capture velocity at the hood long before they cost you a cartridge.
The arms need a five minute conversation with the operators. A counterbalanced arm only captures if somebody moves it. That is a training item, not an equipment item, and it is the single biggest difference between a source capture system that works and one that becomes an expensive ceiling ornament. We cover it at commissioning rather than leaving it to the manual.
A hard boundary
Non combustible dust only, and that is Parker’s own line
Parker’s application field for the SCB reads non combustible dry dust. We are not going to quote around that. A collector rated for nuisance dust does not become a combustible dust machine because the airflow happens to line up, and a ceiling hung unit that recirculates into an occupied space is the last place to find that out.
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.
The part shops underestimate is how many ordinary materials test combustible. Wood, most grains and sugars, many plastics, aluminum, magnesium, titanium and zirconium all sit inside that scope, and published KSt and Pmax values screen for hazard rather than design for it. Design requires lab testing your actual dust, because particle size and moisture move the numbers.
Aluminum, magnesium, titanium and zirconium go to wet collection under NFPA 660’s stated preference. We coordinate the DHA and testing process and prepare documentation your qualified professional engineer reviews and stamps. 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
Two stations, fixed work, and a floor you cannot spare
Parker’s own fields read dust, fume, smoke and source capture media collector, and call out dry dust and fume including welding fume using extraction arms or ducting. That is the honest scope.
Where it lands is a shop that already knows source capture is the right answer and cannot give up the square footage for a floor unit. A pair of weld benches. A grinding station and a cutting station side by side. A training bay laid out in pairs, where a ceiling unit also keeps the hardware out of reach of everything that gets bumped.
It shows up most often in welding and metal fabrication, in trade and vocational schools, and next to its own sibling: the SCA handles the general room air while the SCB takes the two stations that actually generate the fume.
Fit check
When the SCB is not right for you
Your dust is combustible
This is the first question, not the last. Parker rates the SCB for non combustible dry dust. Wood, grain, sugar, many plastics and reactive metals all commonly test combustible, and that changes the machine, the protection strategy and the standard you are working to. See combustible dust collectors.
You have more than two stations
Two arms is the machine. A third station means a second unit, a floor mounted collector with a duct main, or the SFC sized to the whole bay. Trying to branch a third drop off a two arm unit gets you three underperforming hoods.
The work moves around the bay
Arms capture what is in front of them. If the part is on a crane, or the operator works the length of a long weldment, no arm follows that. Ambient collection with the SCA is the honest answer there.
Your roof structure has not been checked
775 lbs before arms and cartridges, hung overhead, plus whatever the arms load into the mount. That is a structural question with a real answer, and it belongs before the order rather than on install day.
Nobody is going to move the hood
We would rather say this before the quote than after the install. If the operators will not reposition an arm, a source capture system underperforms and the money would do more work as ambient collection or a downdraft bench where capture happens without anyone deciding to make it happen.
Oil mist, not dry dust
Machining coolant mist is a different filtration problem and a cartridge collector is the wrong machine for it. That work goes to the SmogHog side of the line.
SCB questions
How much air does the SCB move?
2,000 CFM total, across both arms. That works out to roughly 1,000 CFM at each hood when both stations are running, which is real capture on bench welding as long as the hood is kept close to the arc.
What is the difference between the three part numbers?
Discharge side. 01-10077-0001 discharges rear, the L discharges left and the R discharges right. Same collector, same airflow, same arms. The choice is about how air moves through your building.
What arms does it take?
Two 8 in. diameter counterbalanced extraction arms in 7, 10 or 12 ft. Parker also allows 6 or 8 in. flexible or rigid duct on inlet collars instead, which is the right call when the capture point is fixed rather than moved by hand.
How is it different from the SCA?
The SCB captures at the source through two arms or ducted hoods. The SCA is ambient: it cleans the room air rather than catching fume at the work. Source capture does more with less air when a hood can reach the process, and plenty of shops run both.
Can I use it on combustible dust?
No. Parker’s application field reads non combustible dry dust. Combustible dust needs a collector engineered for it, with a protection strategy driven by your dust hazard analysis and lab testing of your actual material.
Do the arms and filters come with it?
Arms, cartridges and the motor starter are selected and ordered alongside the unit rather than assumed, because arm length and media both depend on your station layout and your process. We put them on the quote by part number so the system arrives able to run.
What power does it need?
230 or 460 volt three phase at 60 Hz, drawing 4.8 to 9.6 amps depending on the supply, on a 3.0 hp motor. Parker builds it for an external motor starter, which we quote with the unit.
How heavy is it and where does it mount?
775 lbs before arms and cartridges, mounted above the plant floor. It measures 98 in. deep, 45 in. wide and 39.625 in. high. The structural check on your roof or hangers comes before the order.
Tell us the stations, the process, and what is at the wall
Those three answers decide the arm length, the mounting height, the media and whether two arms overhead is the right shape of answer at all. You get back a full part number and a firm price.
