静电驻极过滤
Electrostatic electret filtration
以3M“高效静电空气过滤网”为代例,采用突破性携带永久静电滤材，有效阻隔空气中大于0.1微米的颗粒污染物，如粉尘、毛屑、花粉、细菌等，同时超低阻抗确保空调稳定运行及制冷效果。此外，深度容尘设计确保使用寿命更长。当今在家庭及车载空调(如上汽、大众、通用等知名品牌畅销车型)以及一些商用建筑领域(如鸟巢、北京饭店、首都机场三期)得到广泛应用。
Taking 3M "high efficiency electrostatic air filter network" as an example, it uses a breakthrough permanent electrostatic filter to effectively block particulate pollutants, such as dust, wool, pollen, bacteria, and so on in the air. At the same time, the ultra-low impedance ensures the stable operation and cooling effect of the air conditioner. In addition, the deep dust design ensures a longer life. Today in the home and vehicle air conditioning (such as SAIC, Volkswagen, general and other well-known brands of famous brands) as well as a number of commercial construction fields (such as bird's nest, Beijing Hotel, capital airport three) have been widely used.
传统的标准过滤介质能非常有效地去除10微米以上的颗粒物。当颗粒物的粒径除至5微米，2微米甚至亚微米的范围时，高效的机械式过滤系统就会变得比较昂贵，且风阻会显著增加。通过静电驻极材料过滤,能以较低的能源消耗达到很高的捕获效率，同时兼具静电除尘低风阻的优点，但无需外接上万伏的电压，故不会产生臭氧,且由于其组成为聚丙烯材质，很方便抛弃处理。
The traditional standard filtration media can remove particles more than 10 microns very effectively. When the particle size is 5 microns, 2 micrometers or even sub microns, the efficient mechanical filtration system will become more expensive and the wind resistance will increase significantly. Through electrostatic electret material filtering, it can achieve high capture efficiency with lower energy consumption, and also has the advantages of electrostatic precipitator and low wind resistance, but it does not need to connect the voltage of tens of thousands of volts. Therefore, it will not produce ozone, and because its composition is made of polypropylene, it is very convenient to abandon the treatment.
