Source Capture Aerodynamics
Welding generates a highly toxic plume of sub-micron metallic oxides and shielding gases. Dilution ventilation is ineffective for protecting the welder's breathing zone. Welding fume extractors rely on source capture aerodynamics, utilizing articulating extraction arms to generate a high-velocity negative pressure zone directly over the weld pool.
Multi-Stage Filtration Architecture
To safely recirculate the air back into the facility, the extractor utilizes a multi-stage filtration payload. A metallic spark-arrestor baffle extinguishes live embers, followed by a pleated pre-filter, and terminating in a PTFE-coated HEPA cartridge capable of trapping 99.9% of hexavalent chromium and manganese particulates.
