What is the difference between a medium efficiency filter panel and a bag type?
What is the difference between a medium efficiency filter panel and a bag type?Medium efficiency filter is divided into two types of bags and non-bags, efficiency including F5, F6, F7, F8, and F9, bags of different sizes, the number of bags is also different, non-bags are often made of medium efficiency filter plate type, plate type has a cover mesh folding type, flat and keel type can be selected, air conditioning medium efficiency filter material complete, medium efficiency filter plate type and bag type what is the difference?Medium efficiency filter plate type is suitable for: A. Air-conditioning system medium efficiency filter B. Pharmaceutical, hospital, cosmetics, semiconductor electronics, precision machinery, food, and other industries air filtration C. Spray paint line air medium efficiency filtration. The design features of the plate-type medium efficiency filter are large air volume, small resistance, and sturdy structure. General application of plate type medium efficiency filter: air conditioning system intermediate filtration, pharmaceutical, hospital, cosmetic, semiconductor electronic precision machinery, food, and other industries air filtration. Medium efficiency filter material is complete: polyester fiber; sealant: polyurethane adhesive; outer frame: aluminum alloy frame, galvanized plate frame. The bag type medium efficiency filter is mainly made of aluminum and zinc, which gives the product a stable and sturdy appearance, and each filter bag is fixed with a metal guard strip. Bag filter design features: capture 1~5um particles of dust and various suspended matter; high dust capacity; low resistance; good air permeability; high filtration efficiency; long service life. Bag-type medium-effect filter applications: air filtration system filtration, clean room secondary filtration, hospitals, pharmaceutical plants, electronic plants, spray paint room higher clean air requirements level filtration system, general building air filtration equipment, high-efficiency filter pre-stage filtration. The main points of the selection of the middle-effect filter: 1. The main control parameters for the selection of medium efficiency filter products are rated air volume, filtration efficiency under rated air volume, primary resistance under rated air volume, dust capacity, and external dimensions, etc. 2. According to JG/T22-1999 "General ventilation air filter performance test method" the method of inspection, the efficiency of atmospheric dust counting ≥ 1.0μm particles ≥ 20% and < 70% of the filter for the medium efficiency air filter. 3. Commonly used filter media for medium efficiency filters are glass fiber, non-woven fabric, etc. 4. The manufacturer should provide the dust capacity of the filter. 5. The initial resistance of the medium efficiency filter should be ≤ 80 Pa. When designing, the final resistance can be two times the initial resistance as the calculated resistance of the filter. 6. The initial resistance of the filter shall not exceed 10% of the sample resistance of the product. After the filter media that can be regenerated or cleaned is regenerated and cleaned, the efficiency shall be not less than 85% of the original index and the resistance shall not be higher than 115% of the original index. 7. The air filter shall meet the requirements of fire prevention and the flash point of the paint of the air filter shall be not less than 163°C. 8. The medium-effect filter should not be used independently and should be used in combination with the coarse-effect air filter. |
