1. Air filtration technology mainly adopts a filtration separation method: by setting different performance filters, suspended dust particles and microorganisms in the air are removed, that is, dust particles are captured and retained through filter media to ensure the cleanliness requirements of the incoming air volume. The filter material used is fine diameter fibers, which can not only facilitate the smooth passage of airflow but also effectively capture dust particles.
2. The dust filtered by clean technology control generally consists of dust particles ranging from 0.1 to 10 μ m, with smaller particle sizes and containing both solid and liquid particles; The suspended organic particles in the atmosphere include microorganisms, plant pollen, flocs, and hairs. Microorganisms generally include viruses, rickettsia, bacteria, fungi, protozoa, and algae. The main control measures for air purification are bacteria, fungi, and viruses. Because microorganisms mainly adhere to dust particles, effectively controlling dust particles in the air can also effectively control bacteria, fungi, and viruses in the air. To achieve this, it is necessary to filter through a particulate filter with barrier properties. Generally, the filtration efficiency of ordinary high-efficiency filters for bacteria can reach 99.996%, which can basically meet the filtration and purification requirements of biological cleanrooms.
