What are the classifications of air filters What are the classification criteria of air filters What are the classifications of air filters? What are the classification criteria of air filters? Air filter classification standard What are the classification of air filters according to working principle Air filter can be divided into compressed air filter, primary effect filter, medium efficiency filter, high efficiency filter and sub-high efficiency model according to its working principle. What are the classification of air filters according to the structure There are many types of air filters for clean rooms, according to the structure: 1. flat filter 2. foldable filter 3. bag filter 4. foldable filter with separator 5. foldable without separator Filters are classified according to filtration efficiency, which is the most common method; according to the provisions of national standards GB / T14295-93 "Air Filter" and GB13554-92 "High Efficiency Air Filter", under the rated air volume: 1. Coarse effect filtration 2. Medium-efficiency filter 3. High-efficiency filter 4. Sub-high efficiency filter 5. High-efficiency filter (ultra-high efficiency filter) Detailed introduction of air filter categories air filter It is usually made of man-made fiber filter material, and the outer frame is made of a strong, moisture-proof cardboard frame. Under normal operating environment, it will not be deformed, cracked or twisted. The frame is fixed diagonally before and after the frame. The filter material is tightly bonded to the outer frame to prevent air leakage. Medium efficiency air filter It is composed of artificial fiber and galvanized iron. There are various efficiencies to choose from, including 40-45%, 60-65%, 80-85%, 90-95%. The flange consists of 26 gauge galvanized iron. This series of products can be used in industrial, commercial, hospital, school, building and other various factory air-conditioning equipment (the primary filtration of air-conditioning system to protect the next-level filter and system itself in the system, in the cleanliness requirements of air purification In less strict places, the air processed by the medium-efficiency filter can be sent directly to the user), and can also be installed in the air inlet device of the gas turbine or the computer room to extend the service life of the device. The primary effect filter is mainly used for primary filtration of air conditioning and ventilation systems, clean room return air filtration, and pre-filtration of local high-efficiency filtration devices. It is mainly used for filtering dust particles with a particle size of 5 μm and above, and is tested by the weight method. It is also used for primary protection of multi-stage filtration systems. The filter materials are non-woven fabric, nylon mesh, aluminum wave mesh, stainless steel mesh, etc. The air outlet surface of the non-woven fabric filter material has been smoothed to prevent the secondary pollution caused by the non-woven fiber breaking and flying. Primary effect filter It is mainly used for primary filtration of air conditioning and ventilation systems, clean room return air filtration, and pre-filtration of local high-efficiency filtration devices. It is mainly used for filtering dust particles with a particle size of 5 μm and above, and is tested by the weight method. It is also used for primary protection of multi-stage filtration systems. The filter materials are non-woven fabric, nylon mesh, aluminum wave mesh, stainless steel mesh, etc. The air outlet surface of the non-woven fabric filter material has been smoothed to prevent the secondary pollution caused by the non-woven fiber breaking and flying. DC, DZ type coarse medium-efficiency bag filter adopts primary and medium-efficiency non-woven fabric as filter material, cold plate sprayed plastic as frame, as the first and second filter, the product has large dust capacity, low resistance and can be cleaned According to different advantages such as use environment and material selection, the filter efficiency grades are divided into F5, F6, F7 and F8. High efficiency air filter It is suitable for normal temperature and humidity, and allows air filtration containing trace amounts of acid and alkali organic solvents. The product has high efficiency, but high resistance and small dust holding capacity. It is widely used in precision fields such as aerospace, aviation, electronics, pharmaceuticals, and bioengineering.
