PVDF filter cartridge is composed of hydrophobic and hydrophilic PVDF filter membrane and diversion layer. The filter material is folded by the machine, and then the filter material and the shell are sealed, the interior and the shell are fixed, and the end caps are welded.
No adhesives, no media shedding.
Can be used for gas and liquid filtration. In the filtration industry, PVDF filter cartridges are generally used for terminal filter elements such as particle removal of corrosive liquids, sterilization filtration and oxidative gas sterilization filtration, and are widely used.
It is an essential operating element in various media filtration and water treatment processes in chemical, pharmaceutical, electronic, water treatment and other industries. It has a very good removal effect on colloidal particles such as silica and microbial debris.
Available in both hydrophobic and hydrophilic types.
- The filter element is cleaned with pure water; the filter element has no medium falling off;
- Ozone resistance, strong acid and alkali resistance and halogen corrosion resistance;
- The filter element is tested for integrity;
- Strong negative static; no adhesive; good pollution resistance; good high-temperature resistance.
- Integrity test of polyvinylidene fluoride pleated filter element (minimum bubble point, 25℃, 60% isopropyl alcohol)
In the electronics industry, high-purity gas-particle removal filtration, electronic chemical particle removal filtration, high-purity water storage tank gas exchange;
In the biopharmaceutical industry, it is used for sterile gas exchange of pure water tank respirator, water injection tank respirator, and batching tank respirator; nitrogen and compressed air are filtered; fermentation gas sterilization filtration in the biological fermentation industry, and solvent and solvent sterile filtration;
Sterile gas exchange of storage tank respirator in food and beverage industry, sterile gas filtration of edible fungus fermentation tank liquid culture.
Particle removal of organic solvents, chemical products, particle removal of high-purity chemical reagents, and other occasions.
