DustHog equipment
DustHog units we specify for cutting tables
Plasma and laser cutting throw fine metal fume, and whether that fume is combustible depends on what you are cutting. These are the units we size for cutting tables, with the manufacturer’s own dust rating on each.
DustHog SFC Modular Cartridge Collector
Twenty builds from 1,275 to 102,000 CFM. DustHog rates the SFC for combustible and non combustible dry dust.

These submicron fumes stay airborne for hours, penetrate deep into lung tissue, and can damage the optics on your laser equipment if left uncaptured. The fume composition varies significantly depending on whether you’re cutting mild steel, stainless, aluminum, or coated materials, and your filtration needs to account for that.
The right collector for a cutting table depends on several factors: table width and zoning, number of cutting heads, material type, cutting speed, and torch on-time. Alongside the DustHog line, we carry stationary filtration from Plymovent and MicroAir, two manufacturers that build systems specifically rated for the heavy loading and fine particle sizes that plasma and laser cutting produce. Both offer self-cleaning cartridge technology that maintains airflow without constant filter replacement.
If you’re cutting combustible metals like aluminum, titanium, or magnesium, dry cartridge collectors aren’t the right answer. Wet collectors are the preferred approach under NFPA 660 for those materials, and we carry the MicroAir Hydromax line specifically for that application.
Installation is handled by an independent ICAP Certified crew or your own contractor.

Compliance: Preferred approach under NFPA 660
Advantage: Captures reactive metal dust in water
Best For: Plasma cutting reactive metals
Design Considerations
How We Size a Plasma & Laser Collector
Table Size & Zoning
Wider tables need more airflow. Downdraft tables are partitioned into zones so only the active cutting zone draws air, reducing total CFM requirements and collector size. The number of open zones during cutting determines the peak airflow demand.
Air-to-Cloth Ratio
Plasma and laser fume is extremely fine. You need a lower air-to-cloth ratio (1:1 to 2:1) than general dust applications. This means more filter media per CFM, which keeps velocity through the media low enough to actually capture submicron particles.
Spark Protection
Plasma and oxy-fuel cutting throw hot sparks and molten metal that can ignite cartridge filters. Upstream spark arrestors quench burning embers before they reach the collector. Some systems also include smoke detectors in the clean air plenum.
Material Being Cut
Mild steel, stainless, galvanized, aluminum, and coated materials all produce different fume compositions. Combustible metals (aluminum, titanium, magnesium) call for Wet collectors, the preferred approach under NFPA 660. We do not recommend an indoor dry cartridge system for reactive metal dust.
Self-Cleaning Is Essential
Thermal cutting produces continuous heavy loading. Without automatic pulse cleaning, filters blind quickly and airflow drops, meaning fume escapes the table. Both Plymovent’s RamAir and MicroAir’s Roto-Pulse systems clean filters during operation to maintain consistent capture velocity.
Explosion Protection
Any dry collector handling combustible metal fume needs explosion protection: venting per NFPA 68, suppression or isolation per NFPA 69, and proper grounding. All MicroAir FRP FORCE and RP models can be configured with explosion vents and backblast dampers.
Applications
Common Plasma & Laser Applications
Plasma Cutting Tables
Downdraft and water-table extraction for CNC plasma cutting, with zoned collection to match active cutting area.
Fiber & CO2 Laser Cutting
Ultrafine metallic oxide capture from precision metal cutting. Fiber lasers produce extremely fine fume that requires low air-to-cloth ratios.
Laser Engraving & Marking
Fume and odor control for wood, acrylic, leather, and paper processing. Activated carbon stages for VOC and odor removal.
Oxy-Fuel Cutting
Heavy fume and hot slag from torch cutting. Spark arrestors are critical upstream of the collector to prevent filter ignition.
Laser Welding
Fine fume capture for micro-welding and precision laser joining applications in controlled environments.
Metal 3D Printing
Safe capture of metal powder sintering fumes from additive manufacturing. Often requires inert atmosphere considerations.
Thermal Spray Coating
Heavy-duty systems for plasma spray, flame spray, and HVOF operations producing concentrated metallic fume.
Robotic Cutting Cells
Enclosed and semi-enclosed automated cutting stations with integrated fume extraction, designed to run multi-shift and 24/7.
Decision Guide

Modular, bank together for 20,000+ CFM
Combustible Metals
Cutting aluminum, titanium, magnesium, or their alloys. We do not recommend dry cartridge collectors for these materials.
