Source Capture vs. Ambient Air Systems
When it comes to welding, an ambient air system is not enough of a solution to mitigate dangers specific to welding. Either source capture welding fume extractors or overhead and side draft hoods are typically the answer.

Plant A uses an ambient air ventilation system operating at 30-40,000 CPM (cubic feet per minute) in order to maintain optimal indoor air quality. The air is only filtered after it has entered the welders’ breathing zones and puts all employees at risk.
Plant B uses source capture welding fume extractors requiring approximately 1,000 CPM per welder to maintain air quality. Company experiencing substantial energy cost saving over its ambient air system and achieved less hazardous workstations for their welders.
