Air filter material uses PP / PET resin as the main raw material, through a special spinning processing technology. Dust holding capacity, acid and alkali. From the early effect, efficiency, high school efficiency until sub-efficient and efficient. For different occasions, the use of clean air requirements, the production made into a variety of fiber structure to form a different size of the normal series, plus static series. According to the different requirements of the production of compact, coarse filter, microfiltration, ultra-microfiltration, linen, paper filter, film, wood pulp fiber and other forms.
