High vacuum smoke and dust purifier, also known as high negative pressure smoke and dust purifier, refers to a high-pressure fan with a negative pressure greater than 10kPa, which is different from ordinary welding smoke purifiers. The JC-NF-200 high negative pressure smoke and dust purifier adopts two-stage separation and is a dust removal equipment designed specifically for dry, oil-free, and corrosion-free welding smoke generated during welding, cutting, and polishing processes.
