The required CFM (cubic feet per minute) for a welding fume extractor typically ranges from 600 to 1,200 CFM per extraction arm, depending on the welding process and the amount of fumes generated. For most general welding applications, around 800 to 1,000 CFM is recommended to effectively capture and remove fumes at the source. Always consult manufacturer guidelines and consider workspace size and ventilation needs for optimal performance.
