Central & Wall-Mounted Fume Extractors

Central & Stationary Weld Fume Extractors — Fixed Source Capture for Dedicated Stations

When welders work at the same station every day, a portable unit on casters is the wrong tool. Portables are built for flexibility, they trade some performance and convenience for mobility. A stationary or centrally-ducted fume extractor is built for the opposite: maximum capture efficiency, larger filter capacity, longer service intervals, and a cleaner installation that doesn’t occupy floor space around the weld cell. Stationary units mount to a wall or post at a fixed station with one or two extraction arms. Central systems serve multiple stations through a common duct network and a single filtration unit — the same concept as a central dust collection system, applied specifically to weld fume. Both approaches deliver better long-term economics than running multiple portables on a production floor. We design both types: single-station wall-mount units sized for the specific welding process, and central ducted systems serving anywhere from two stations to an entire weld department. Call us with your station count, process, and base materials and we’ll develop the system layout and spec.

• Wall-Mount / Post-Mount: Fixed installation at dedicated stations; cleaner shop layout than portable units
• Central Ducted Systems: One filtration unit serves multiple weld stations via ductwork — lower cost per station at scale
• Airflow Range: Single-station units typically 800–2,000 CFM; central systems sized to total station count and duty cycle
• Filtration: Multi-stage with spark arrestor and fire-retardant primary cartridge; HEPA after-filter for stainless, galvanized, and chrome-bearing materials
• Extraction Arms: Articulating arms from 7′ to 14′; one or two arms per station
• Pulse-Jet Cleaning: Standard on production-duty units — automatic filter cleaning extends service intervals
• Controls: On/off to full VFD-integrated demand control depending on system size

Portable vs. Stationary vs. Central — Choosing the Right Approach

Factor	Portable	Stationary (Wall/Post)	Central Ducted
Station flexibility	High — moves with operator	Fixed location	Fixed locations
Best for	Maintenance, job shops, rotating work	1–3 dedicated weld stations	4+ stations, production welding departments
Installation cost	Lowest — plug in and roll	Low — mount and connect arm	Higher upfront; lower per-station at scale
Floor space	Unit occupies floor around station	Wall/post mounted — no floor footprint	Collector located remotely
Filter service	Per unit — multiple change points	Per unit	Single change point for all stations
Hex chrome / HEPA	Available as option	Available as option	Available — single HEPA stage serves all stations

OSHA hexavalent chromium PEL: 0.005 mg/m³. Stainless steel, galvanized, and chrome-containing base metals require HEPA-grade filtration for compliance. We specify the correct filtration for your materials.
