It's composed of the filtering materials in electret status made from the isotactic polypropylene with high melting index. It can effectively filter the dusts in 0. 3µ M diameter. Under the same wind volume, it has reduced the depth of filters and is convenient for batch mechanized production. Such filter series can reduce the weight of filters and the static pressure trunk volume of purifying equipment. And such materials as super-thin glass fiber filtering materials and cleanable materials can be used according to the customers' requirements.
It can be used in dusts collectors, air purifiers and the cleaning places that require high cleaning level.
