Industrial Grade Excellence
PP Pleated Filter Cartridge Manufacturer, Polypropylene Pleated Filter Cartridges Supplier in India
VVIOK Industry is an established, high-precision pleated filter cartridge manufacturer and technical engineering pioneer based in Ahmedabad, Gujarat. Designed to satisfy rigorous micro-filtration demands across sterile pharmaceuticals, biotechnology, semiconductor manufacturing, chemical processing, and food & beverage operations, our advanced SS and PP pleated filter cartridge solutions deliver superior particle retention efficiency, high throughput, and exceptionally low initial pressure drop. Certified under ISO 9001:2015 quality standards and complying with US FDA 21 CFR regulations for food and biological contact, our cartridges provide absolute-rated clarification for critical process streams.
As an accredited, global pleated filter cartridge supplier, VVIOK Industry engineers each filter element using 100% pure virgin polypropylene micro-fiber media. Our state-of-the-art pleated matrix maximizes filtration surface area—offering up to 0.65 m² (7.0 sq. ft.) of active media per 10-inch length. This dense pleat configuration delivers high dirt-holding capacity and dramatically extends on-stream operating life compared to conventional depth or spun cartridges. Recognized among India's foremost pleated cartridge filters manufacturer facilities, we construct these cartridges using thermal melt-bonding technology, completely eliminating glues, binders, resins, or surfactants to ensure zero fiber migration and ultra-low extractables.
Our heavy-duty polypropylene pleated filter cartridges are engineered with reinforced polypropylene inner cores, outer cages, and thermally welded end-caps to withstand continuous operating temperatures up to 80°C and forward differential collapse pressures up to 4.2 bar (60 psi). Complementing our polymeric range, we also design robust stainless steel pleated filter cartridge assemblies and re-usable ss pleated filter cartridge units fabricated from AISI 304/316L woven wire mesh, engineered specifically for high-temperature steam sterilization, corrosive solvents, and differential pressures exceeding 10 bar. Whether your system requires a standard double open end (DOE) configuration or sanitary single open end (SOE) designs such as Code 7 (226 O-ring with bayonet locking tabs) or Code 3 (222 O-ring with flat cap), each pleated polypropylene filter cartridge guarantees leak-free, bypass-free seating inside single or multi-cartridge housings.
Every batch undergoes rigorous quality assurance, including forward flow integrity testing, bubble point validation, and DI water flushing to meet high-purity USP Class VI biological safety criteria. With micron ratings ranging from fine 0.1 µm and 0.2 µm absolute membranes up to 100 µm nominal clarifying grades, and standard lengths from 10 inches to 40 inches, VVIOK Industry delivers customized solutions tailored to exact client operational requirements worldwide.
