Pleated membrane filter cartridges are constructed with high quality membrane and polypropylene support multi-layers and components. Membrane filter cartridges are 100% integrity tested in production with full lot traceability of materials. Membrane cartridge filters are manufactured, flushed, tested and packaged in clean room, consistent filtration efficiency and high flow rate by wide chemical compatibility, large surface area designed for maximum throughput and high dirt holding capacity. Advanced membrane materials include Nylon, PTFE, PES, Glass fiber, PVDF etc., can meet high purity filtration requirements for prefiltration and final filtration, such as Water Treatment, Food & Beverage, Medicinal Filtration, Solvents, Semiconductor, Cosmetics, Bottled Water and many critical industries.
