With the acceleration of industrial footsteps, some industries requiring high cleanliness are also changing day by day, and people are becoming more and more sensitive to pathogenic bacteria. But the working environment of modern industry should be in a space with high cleanliness that nature can not reach. Although some clean room equipment for aseptic and dustless purification projects, such as dustless chamber or aseptic chamber, is now being used, the biggest problem still lies with the staff. Because the staff is the largest source of dust, it is difficult to remove the dust attached to the staff when they enter the clean room or sterile room. Therefore, it is necessary to install a jet dedusting equipment in the air shower room to remove the dust and bacteria attached to the staff and clothes.
