Application Of Air Filtration Media

1. For cleanroom air conditioning purification system

This is the main application direction of air filter media. The cleanroom air-conditioning system is usually equipped with three filters. Generally, the coarse and medium-efficiency air filters are installed in the air-conditioning unit, and an air filter is added at the end of the air supply. The filter materials of the coarse-efficiency air filter are mainly glass fiber, PP, PET, and wire mesh, which can filter out dust particles above 5m; the medium-efficiency air filter, except for the wire mesh, has other materials similar to the coarse-effect air filter, but Its fiber diameter is smaller, which can effectively filter dust particles above 1m. HEPA filters are mainly made of ultra-fine glass fibers and PP materials; the efficiency of the sodium flame method of domestic ultra-fine glass fibers can reach 99.99999, but in recent years, membrane filtration has gradually penetrated into this field. Cleanrooms can generally be divided into two categories: industrial cleanrooms and biological cleanrooms. Industrial clean rooms are mainly used for some production processes that require high air cleanliness, which mainly include the electronics industry, films, optical instruments, machinery, etc., such as in the electronics industry, certain processes in the production of ultra-large-scale integrated circuits, The controlled particle size of suspended particles in the air has been reduced to 0.1m. The biological clean room not only has requirements on the dust concentration in the room but also on the number of bacteria. The bacteria attached to the dust particles can be filtered out through the filter, which mainly includes the food industry, operating room, pharmaceutical factory, and biological laboratory.

2. For an ordinary air conditioning system

Ordinary air-conditioning systems are generally equipped with coarse-efficiency air filters in the air-conditioning unit, and medium-efficiency air filters are also installed after the coarse-efficiency air filters for those with slightly higher requirements.

3. Ordinary families use

This mainly includes household air conditioners and air purifiers, etc. Most of the filter materials used in household air conditioners are ordinary plastic woven filters with large pores, which can only filter out larger dust particles. Indoor air purifiers are another potential market for air filtration materials. Indoor air quality has been a research hotspot since the 1990s. The air contains smoke, mold, spores, bacteria, fibers, dust particles, etc. How to eliminate these pollutions and create a better indoor air environment is very important to human health. . Air purifiers are an effective way to remove indoor pollutants, and the filter material of air purifiers is generally ultra-fine glass fiber. Air purifiers are developing rapidly abroad. Ordinary air purifiers cannot remove harmful indoor gases. The components of these gases are very complex. Only cigarette smoke contains hundreds of gas components, plus aldehydes and benzenes emitted from decoration materials, and various pollution sources. CO, SO2, NOX, NH3, etc. directly endanger human health. To eliminate this hazard, functional air filter materials are required. The commonly used materials are activated carbon or activated carbon fiber.
