In metal processing, smoke and gases are created by welding, cutting and associated processes and are classed as hazardous substances according to current regulations. Welding fumes are a health hazard and in parts may even cause cancer and cause genetic alterations. For more than 35 years, welders have been relying on the effective welding fumes extraction by KEMPER. Every extraction and filter plant by KEMPER collects the welding fumes very effectively and filters even ultra-fine dust particles safely and reliably from contaminated air.
