The working principle of high-efficiency filters

High efficiency air filter is an air purification equipment with high usage rate in industrial places. It can capture harmful particles and dust impurities in the air, and sterilize and purify them, making the air clean again. The high-efficiency air purifier has high filtration efficiency and a large dust capacity, making it suitable for places with high industrial workload and effectively protecting the respiratory health of workers. Let's take a look at this type of air filter.

High efficiency air filters are mainly used to capture particulate dust and various suspended solids below 0.5um. It is made of ultra-fine glass fiber paper as filter material, offset paper, aluminum film and other materials as partition board, and glued with wood frame aluminum alloy. It is made of special silicone rubber. It is odorless, the surface will not harden, and there will be no cracks for a long time. It has stable chemical properties, corrosion resistance, and can absorb the stress generated by Thermal expansion without cracking. It has moderate hardness and good elastic recovery.

The high-efficiency air filter cleaning technology controls the filtration of dust particles, which are generally 0.110m in size and contain both solid and liquid particles; The organic particles suspended in the atmosphere include microorganisms, plant pollen, flocs, and hairs. Microorganisms generally include viruses, Rickettsia, bacteria, fungi, protozoa, and algae. The HEPA filter mainly controls bacteria, fungi and viruses.

Because microorganisms mainly adhere to dust particles, effective control of 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 particulate high-efficiency air filters with barrier properties. Generally, the filtration efficiency of ordinary high-efficiency air filters for bacteria can reach 99.996, which can basically meet the filtration and purification requirements of biological cleanrooms.

Air filtration technology mainly adopts filtration and separation methods: by setting high-efficiency air filters with different performance, suspended dust particles and microorganisms in the air are removed, that is, dust particles are captured and retained through filter materials to ensure the cleanliness requirements of the incoming air volume. The filter material used in high-efficiency air filters is fine diameter fibers, which can not only facilitate the smooth passage of airflow but also effectively capture dust particles.
