PVDF series filter adopts hydrophobic PTFE/hydrophilic PTFE filtermembrane, and the outer cage, center core and end cap are all madeof PVDF material, which makes the filter element has particularlyexcellent chemical resistance performance. At the same time, it haslow precipitation, ensuring the filter element can be highly efficient,long-term filtering of strong corrosive acids, alkalis and organicsolvents, etc.
