Welding & Fabrication Vacuum Solutions
The arc makes fume. The floor makes dust. Different systems.
Fume extraction at the arc is exposure control for what's airborne. Everything that settles — grinding fines, cooled spatter, slag chips, mixed metal dust across fixtures and floors — belongs to the housekeeping program, and PrestiVac recovery collects it without the blow-down that puts it right back in the air.

Maximum Uptime
Continuous-duty performance
Overview
Fabrication makes two particulate streams with two owners. Fume — the ultrafine airborne fraction created at the arc — is the extraction system's job, captured at the source while welding happens. The settled stream — grinding fines, cooled spatter and slag, blasting carryover, mixed metal dust on fixtures, ledges and floors — is the vacuum program's job. Blow-down bridges the two in exactly the wrong direction: it re-suspends settled fines into breathing zones and onto surfaces waiting for the next weld.
Grinding Fines
The finest, most sensitive fraction
Spatter & Slag
Cooled solids and flux residues
Mixed Metal Dust
Carbon, stainless & coated steels
Weld-Prep Cleanliness
Contamination off the joint
Challenges in welding & fabrication
- Fume-versus-dust confusion leaves the settled stream unmanaged
- Grinding fines of aluminum and other reactive metals are combustible
- Blow-down re-suspends fines into breathing zones and onto fresh joints
- Spatter and slag must cool before recovery — hot material never enters a unit
- Stainless and coated-steel dusts carry occupational exposure limits
- Housekeeping is a documented, inspectable compliance obligation
Why vacuum recovery?
- Separates the streams correctly: extraction owns the arc, recovery owns the floor
- Grounded, rated equipment in a space where ignition sources are guaranteed
- HEPA retention for dusts governed by exposure limits
- Single-pass removal ends the resuspend-and-resettle cycle
- Clean fixtures and joints protect weld quality, not just compliance
- Supports OSHA housekeeping obligations with documented methods
Solution benefits
Better Safety
Grounded recovery in a shop where sparks and hot work are the day's normal.
Higher Productivity
Stations turn over in one pass — no sweep, resettle, sweep again.
Cost Savings
Grit off the ways, fixtures and finished work cuts rework and wear.
Cleaner Workplace
HEPA-retained exhaust keeps exposure-limit dusts out of the air.

Welding & Fabrication FAQ
We have fume extractors — why do we need vacuums too?
Different jobs. Extraction captures the ultrafine fume plume at the arc while welding happens; it does nothing about the grinding fines, spatter and mixed dust that settle across the shop. The vacuum program owns the settled stream — neither system substitutes for the other.
Can I vacuum up hot slag and spatter?
No — hot or smoldering material never enters a vacuum. Let spatter and slag cool, then recover; schedule station cleanup after hot work or work a cooled zone. The rule is absolute regardless of unit rating.
Are welding-area dusts actually combustible?
The grinding fines of aluminum and other reactive metals are; carbon-steel dust is generally less severe. The mix and your Dust Hazard Analysis govern — and since ignition sources are guaranteed in a fab shop, grounded, rated recovery equipment is the sensible default.
What about stainless and galvanized dust?
Settled dusts from stainless and coated-steel work carry occupational exposure limits, which makes HEPA retention and sealed disposal the exposure controls for the cleanup side. The fume-side limits belong to the extraction system at the arc.
