Composite Nonwoven Air Filter: A Review
The air quality is a very critical environmental factor that affects human health and wellbeing. The interior as well as exterior surroundings around the human beings, require healthy, comfortable & productive environment. Besides human beings, many manufacturing industries, food processing industries, industrial process lines, electronic appliances & energy converting devices also require clean & particulate free air to perform efficiently & effectively. In gas turbines, a large amount of air is generally required for its operation. The cleanliness of the air is of primary importance for the turbine performance & its life expectancy. As known, the dirty intake of air will cause erosion, fouling, corrosion & cooling passage plugging. In case of cars, buses, trucks & other equipments, the particulate air intake causes fatal damage of finely tuned critical combustion engine components & consequently resulting in complete failure of the system. Semiconductor industries are chemically intensive industry which generates many chemical & physical hazards. The workplace of the semiconductor manufacturing lines requires maintaining extremely clean air with less than one particle per cubic meter to make the semiconductor functioning properly as well as to prevent work-related illness.
