Industrial Grade Excellence
PTFE Pleated Filter Cartridge Manufacturer, PTFE Membrane Filter Supplier in India
VVIOK Industry is an established, high-precision ss ptfe filter cartridges manufacturer and technical filtration engineering leader based in Ahmedabad, Gujarat. Engineered to address critical separation challenges across sterile pharmaceutical venting, biotechnology fermentation, semiconductor manufacturing, aggressive chemical handling, and compressed gas sterilization, our advanced ptfe pleated filter cartridge solutions deliver absolute particle retention, superior chemical inertness, and ultra-low extractables. Constructed with expanded polytetrafluoroethylene (ePTFE) membrane media supported by virgin polypropylene or stainless steel reinforcement cages, these cartridges maintain uncompromised structural integrity under extreme operating conditions.
Our high-efficiency ptfe membrane filter cartridge elements are available in naturally hydrophobic configurations for sterile tank venting, compressed air, and gas drying, as well as surface-modified hydrophilic versions for aggressive aqueous acids, photoresists, and active pharmaceutical ingredients (APIs). Complementing our fluoropolymer portfolio, VVIOK Industry also manufactures high-performance nylon pleated filter cartridge units—utilizing naturally hydrophilic Nylon-66 membranes for non-protein-binding terminal clarification of sterile biologicals and specialty organic solvents.
Every teflon cartridge filter produced at our cleanroom facility undergoes 100% automated integrity testing, including bubble point and water intrusion testing (WIT), ensuring zero microbial or particulate bypass. Whether fitted with standard Double Open End (DOE) or sanitary Single Open End (SOE) Code 7 (226 Bayonet) and Code 3 (222 Flat) end adapters, our PTFE filter cartridges withstand repeated clean-in-place (CIP) and autoclave sterilization cycles, guaranteeing unmatched process security across global industrial installations.
