Baghouse dust collectors, shaker to pulse jet
You get a baghouse designed around NFPA 660 and your dust, airflow, and temperature, from DustHog shaker units to Scientific pulse jet baghouses.
Baghouse units
The baghouse and shaker units we design with, and what each one is for
Your high volume, large particle dust is where a baghouse earns its place. Nobody here ships you a box and wishes you luck. Every system is designed around your dust, with startup support and performance verification once your installer has it running. These are the units we specify for that duty.
DustHog SDC Self Contained Shaker Collector
Nine models, SDC-140 to SDC-1050, from 420 to 8,400 CFM nominal airflow. Shaker cleaned bags with no compressed air needed, and a membrane explosion vent available as an add-on.

Pulse jet baghouses with Scientific’s patented supersonic cleaning nozzle, built in top removal, bottom removal and horizontal configurations for heavy dust loads.
Get a large baghouse sized to your dustScientific Cyclone Pre-Separators
A cyclone ahead of your baghouse drops heavy, coarse and abrasive dust before it reaches the bags. Grouped for larger volumes, with rotary airlock discharge available.

Get a free system reviewYour high-volume dust problem needs more than an off-the-shelf unit. It needs a system designed for your specific dust type, airflow, temperature, and facility layout. Baghouse collectors are the heavy-duty workhorse among industrial dust collectors, using fabric filter bags to handle heavy, high volume dust loads.
Every baghouse we deliver is custom-designed, including properly sized explosion protection when your dust is combustible, which under NFPA 660 covers most industrial dust types.

When to Choose a Baghouse
When a baghouse is the right choice
A baghouse isn’t always the answer. Sometimes a cartridge collector or wet collector fits better. But for these situations, it’s usually the way to go:
High dust loads
When you’re generating large volumes continuously from crushing, grinding, conveying or batch mixing, baghouses handle the volume without choking.
High temperatures
Baghouses run hot dust with the right bag media. We size the media to your actual gas temperature.
Large airflow
When volume grows, Scientific pulse jet baghouses come in top removal, bottom removal, railing top and horizontal builds, and a cyclone ahead of the baghouse takes the coarse load.
Coarse & abrasive dust
Large particle sizes, sharp-edged dust, and fibrous materials that would damage cartridge pleats. Filter bags handle abrasion far better.
Sticky or hygroscopic dust
Moisture-absorbing or sticky materials that cake on cartridge pleats. Bag filters with PTFE membrane media resist caking and clean more reliably.
Dust recovery operations
When captured dust has value, whether recycled material, product recovery or batch return, baghouses with rotary airlock discharge give you clean, controlled material out of the hopper.
Honest Guidance
When a baghouse is not the right choice
You deserve to hear this upfront, before anyone sells you the wrong system. Here’s when something else performs better for you.
Fine, dry dust
Fine, dry dust such as welding fume, metalworking dust, or powder? A cartridge collector usually fits better, in a smaller footprint at lower cost.
Space-constrained facilities
Baghouses need more floor or roof space than cartridge systems at equivalent airflow. If your facility is tight, a cartridge unit or multiple mobile collectors may be the only practical option.
Combustible grinding dust
Aluminum, magnesium, titanium, and other reactive metal grinding call for a wet collector. Wet collection is the approach we recommend, and we do not recommend an indoor dry baghouse for these dusts.
Point-of-source capture
If your priority is capturing fume at individual stations, source capture arms or a downdraft table outperform a central baghouse at a fraction of the cost.
Working with a tight budget
If your budget is tight, a cartridge collector or mobile unit may do the job at a cost that fits. See the 2026 cost guide for what drives the number.
Oil mist or coolant
Your machining mist and coolant smoke are wet, oily loads that fabric bags are not built for. A SmogHog mist collector is designed for that job.

Cleaning Methods
Baghouse cleaning technologies
Your bags get cleaned one of three ways.
Pulse-jet (most common)
Short bursts of compressed air dislodge dust cake from bags while the system runs. Online cleaning means no production downtime. Best for continuous, heavy duty work, and what Scientific baghouses use.
Reverse air
One design you may run into. Gentle low-pressure reversal collapses bags to release dust cake, typically on delicate media and some high-temperature applications. It needs a compartmentalized design for offline cleaning.
Mechanical shaker
A motor-driven mechanism shakes the bags to dislodge dust. No compressed air? The DustHog SDC cleans its bags by shaking and needs none, from 420 to 8,400 CFM.
Applications

Compliance
Baghouse compliance & explosion protection
If your baghouse collects combustible dust, and most industrial dust is combustible, NFPA 660 requires a dust hazard analysis (DHA), and the explosion protection your DHA calls for. NFPA 660 took effect January 1, 2026, and your DHA is reviewed at least every five years and whenever your process changes.
Your dust hazard analysis (DHA) sets the protection strategy, and your dust’s Kst value sizes it, whether that means deflagration venting, chemical suppression, isolation valves, or a combination. We design it into your system from the start, not as an afterthought.
You get a design drawing you own and can take to your authority having jurisdiction and your own engineers.
Standards we design to
→ OSHA 29 CFR 1910.94 (Ventilation)
→ NFPA 660 (Combustible Dust)
→ NFPA 68 (Deflagration Venting)
→ NFPA 69 (Explosion Prevention)
→ Local Fire Marshal Requirements
Ongoing Support
Baghouse filters & maintenance
Your baghouse is only as good as its filter bags. You get replacement bags and cages for all major manufacturers, including polyester, Nomex, fiberglass, PTFE membrane, and specialty media. Browse all filter options.
Regular maintenance keeps your baghouse efficient and your compliance documentation current. Your filters come from us, plus DustHog parts, and hands-on work is contracted directly with an independent ICAP Certified crew. You can submit a maintenance request anytime.

Comparison
Baghouse vs. cartridge, which do you need?
Choose a baghouse when:
→ Dust loads are heavy and continuous
→ Operating temperatures run hot
→ Dust is coarse, abrasive, or fibrous
→ Volume is large and growing
→ Dust is sticky or moisture-absorbing
→ You need dust recovery for recycling
Choose a cartridge collector when:
→ Dust is fine and dry (welding fume, powder)
→ Temperatures are moderate
→ Footprint is limited
→ Volume is modest
→ You need higher efficiency on fine particulate
→ Budget is tighter for smaller operations
Not sure which is right? That’s what your free system review is for. You get a look at your operation and a recommendation for the right collector, with no bias toward one or the other. For a deeper look, read baghouse vs. cartridge dust collectors.
Results from the floor
What changes when a baghouse is set up right
Your baghouse is only as good as the filters in it and the air that reaches it. Two plants, two different fixes, with the numbers.
Roofing granules plant, BHA PulsePleat
Short filter life and high differential pressure were choking airflow. Pleated elements in place of felt bags and cages doubled the filter area. Pressure drop fell to 3.5 to 4.0 in. w.c., airflow rose 34 percent to 50,000 ACFM, and particulate emissions went from 10.73 lbs/hr to 0.48 lbs/hr.

Arizona plastics plant, second-stage cyclone
Holes and thin spots in molded bottles traced back to fines in the regrind. This one is ours: we designed a second-stage cyclone that pulled the fines out before they reached the mold.
Not sure a baghouse is the right collector?
A baghouse earns its footprint on heavy, abrasive or high volume dust. For fine dry dust at lower volume, a cartridge collector usually costs less to own. The comparison walks through where each one is the wrong choice.
