In demanding industrial filtration applications, off‑the‑shelf filter cartridges often fall short when faced with aggressive chemicals, extreme temperatures, or unique process requirements. The Custom PTFE Pleated Cartridge Filter from Jiangsu LongMembrane High-Tech Co., Ltd. is engineered to overcome these limitations, offering a fully customizable solution for harsh fluid and gas filtration challenges.
At the heart of this filter is a biaxially stretched PTFE microporous membrane, which provides excellent chemical resistance and inherent hydrophobic/oleophobic properties. Unlike standard filters, the membrane pore size can be customized to achieve multi‑precision filtration, allowing the cartridge to be tailored for specific impurity removal requirements. The pleated design maximizes surface area, enabling high flow rates while maintaining low pressure drops across a wide range of operating conditions.
The customization extends beyond the membrane. The support structure—including the drainage layer, outer cage, end caps, and core rod—can be configured using polypropylene, PTFE, or stainless‑steel‑reinforced materials to match the chemical compatibility and mechanical strength needs of each application. Sealing options include silicone, fluoro rubber, and EPDM, ensuring reliable leak‑free performance across varied temperatures and fluid types. This modular approach allows the filter to be precisely adapted to everything from solvent recovery and process gas purification to non‑standard precision filtration scenarios.
Performance is another key strength of this filter series. It supports continuous operation up to 80°C and withstands repeated steam sterilization at 121°C for 30 minutes, making it suitable for aseptic processes. Pressure tolerance is equally robust, with a forward differential pressure rating of 0.65 MPa at 25°C and a reverse rating of 0.24 MPa at 80°C. Every cartridge is 100% integrity‑tested before shipment, ensuring defect‑free performance and reliable filtration accuracy. The PTFE construction also provides exceptional resistance to strong acids, alkalis, and corrosive fluids, delivering long service life even under the most challenging conditions.
Typical applications include organic solvent recovery and purification, high‑purity gas filtration in specialty chemical processes, and multi‑stage precision filtration for non‑standard fluid streams. Industries such as fine chemicals, biopharmaceuticals, and specialty manufacturing benefit from the filter's ability to address individualized filtration challenges that standard products cannot solve. By combining customizable materials, robust construction, and rigorous quality control, this filter series offers a complete, tailored solution for complex filtration requirements.
