Industrial Grade Excellence
Pleated Filter Element Manufacturer & Industrial Strainer Company in India
VVIOK Industry is an established, premier industrial strainer manufacturer and high-precision filtration solutions provider based in Ahmedabad, India. In complex fluid handling pipelines, conventional flat wire mesh baskets and cylindrical screens often suffer from limited dirt-holding capacity, rapid clogging, and steep differential pressure spikes. Our high-performance Pleated Filter Element assemblies solve these critical operational challenges by dramatically expanding the active filtration surface area—delivering 3 to 5 times greater dirt retention and significantly extending on-stream runtime across chemical, petrochemical, pharmaceutical, polymer, oil & gas, and industrial water treatment installations worldwide.
As an ISO 9001:2015 certified strainer company, we fabricate each pleated element using multi-layered premium austenitic stainless steels, including AISI 304, AISI 316, and AISI 316L, as well as exotic alloys like Hastelloy and Monel for harsh corrosive fluids. Each element is engineered by folding durable Dutch weave, square weave, or sintered metal fiber mesh around a rigid perforated stainless steel inner core. This structural pleating geometry ensures exceptional collapse resistance under high differential pressures (ΔP up to 25 bar) while maintaining uniform pore distribution and precise micron ratings ranging from 1 micron up to 500 microns.
As a versatile, custom-focused filter strainer manufacturer, VVIOK Industry designs elements that are 100% cleanable and reusable through chemical baths, ultrasonic wash, or automated backflushing. Beyond standard simplex and duplex pipeline filter baskets, our advanced engineering capabilities position us as an innovative self cleaning strainer company, manufacturing replacement pleated inserts, scraper-compatible screens, and backwash elements for continuous, uninterrupted industrial filtration loops.
Whether your process demands custom-dimensioned filter cartridges for high-viscosity resins and polymers or heavy-duty replacement screens compatible with pipeline housings and acme strainers used in utility cooling water and petrochemical networks, VVIOK Industry delivers world-class engineering reliability. Every element undergoes bubble point integrity validation, weld radiography, dimensional verification, and comes backed by EN 10204 3.1 Material Test Certificates (MTC).
