Fume Extraction Systems for the Welding Industry

For a welding shop, the best approach is source capture fume extraction positioned as close to the arc as possible, with filtration media matched to the specific metals and processes being used. General ventilation alone won’t adequately protect your workers.

We always recommend implementing a source capture system, since it removes fumes before they ever reach the welder’s breathing zone. That being said, many shops benefit from using both, with source capture as the primary defense and ambient filtration as a backup to catch any fumes that escape.

Welding fumes contain hazardous metals and compounds such as manganese, hexavalent chromium, and nickel. When inhaled, they can cause serious short and long-term health effects. These range from immediate symptoms like dizziness and nausea to chronic conditions including respiratory disease, neurological damage, and cancer.

OSHA sets Permissible Exposure Limits (PELs) for welding fumes and related substances, and requires employers to implement engineering controls, like fume extraction, to keep worker exposure below those limits. NIOSH and ACGIH also publish recommended exposure limits that are generally more stringent than OSHA’s PELs and are widely referenced as best practice benchmarks.

Filter replacement frequency depends on the volume of welding being done, the types of materials being welded, and the specific extractor model. Generally speaking, heavily used shop filters may need attention every few months. Air Impurities Removal Systems makes it easy to stay on schedule through our Filter Replacement Program, which delivers the right filters to your shop automatically so your equipment keeps performing at its best.
