💡Teijin | News | About the development of “Nano Front® Bug Filter”
Background of development
- Due to the seriousness of air pollution in China, there is a strong demand for reducing the amount of dust emission in urban areas, for example, by restricting the amount of dust discharged from factories to 30 mg / m 3 to 10 mg / m 3 .
- In order to reduce the amount of dust discharged, it is necessary to increase the dust collection amount by specifying the filtering surface of the bag filter in detail. In general, a bag filter attached with a fluorine-based porous membrane is used However, on the other hand, there was a problem such as clogging occurred by specifying the details, the airflow rate decreased.
- In addition, there is a danger of rupture by increasing the exhaust energy, so it is necessary to install additional baggy filters, such as juxtaposing the bags, resulting in high cost.
- To meet such needs, Teijin Frontier has developed the “Nano Front Bug Filter” which simultaneously achieves high collection efficiency and high airflow rate.
