Safe extraction of welding fumes at the source
The RoboVent Extractor reduces the welder’s exposure to welding fumes
Welding fumes are a health hazard, and welders who inhale too many fumes run a higher risk of developing asthma, bronchitis, COPD and cardiovascular disorders. As a result, the U.S. and other international regulatory agencies are moving to more stringent thresholds for weld fume exposures.
The American Conference of Governmental Industrial Hygienists (ACGIH) recommended limit for welding fumes in the workplace is 1 milligram of welding fumes per cubic meter of air (1 mg/m³), over the span of an 8-hour work day.
This norm is, in practice, exceeded in many workplaces. To comply, companies may adopt various measures including room ventilation, mobile extraction hoods, or personal protective equipment such as dust masks or ventilated helmets. The effect of these is often insufficient:
- extraction hoods are not placed close enough to the source
- the objects to be welded are too large
- the welder is very mobile
- welding may take place in enclosed areas (e.g. the hold in a ship)
- personal protective gear is not used correctly
In these cases, an integrated welding fume extraction provision in the welding gun is a more effective measure that is easier for the welder to apply independently in comparison to other means.
The RoboVent Extractor consists of a welding gun with built-in fume extraction. The gun can be connected to a central extraction system or to a stand-alone version without any problems. One advantage of the RoboVent Extractor gun integrated with a RoboVent hi-vac collection system is that it can be used in different workplaces, such as in ships' holds or tanks.
