As a leading manufacturer based in Hengshui, Hebei, China, since 1998, Anping County Boli Hardware Wiremesh Products Factory specializes in producing high-performance filtration solutions. Our PTFE Membrane Coated Fiber Filter Element is engineered for demanding chemical processing environments where extreme temperature resistance and precise filtration are critical. With an annual export value of US$5–10 million and shipments to major ports including Tianjin, Qingdao, and Shanghai, we deliver reliable products trusted by industries worldwide.
This filter element combines a robust fiber substrate with a durable PTFE (polytetrafluoroethylene) membrane coating, offering exceptional resistance to high temperatures up to 260°C and aggressive chemicals. The 1.0μm filtration rating ensures efficient removal of fine particulates, making it ideal for applications such as catalyst recovery, acid filtration, solvent purification, and hot gas cleaning. Designed to maintain consistent performance under harsh conditions, it helps reduce downtime and operational costs.
Key Features & Technical Specifications
- High Temperature Resistance: Continuous operation up to 260°C, suitable for hot gas and liquid filtration.

Frequently Asked Questions (FAQ)
- Can this filter element be used for both liquid and gas filtration? Yes, it is suitable for both liquid and gas applications in chemical processing, provided the temperature and chemical compatibility are within specified limits.
- What is the typical lifespan of the filter element? Lifespan depends on the operating conditions, contaminant load, and cleaning frequency. Under normal conditions, it can last several months to a year. Proper cleaning (backwashing or chemical wash) can extend its life.
- How do I clean the filter element? The PTFE membrane allows for effective backwashing, ultrasonic cleaning, or chemical cleaning with mild solvents. Avoid abrasive methods that could damage the coating.
- Is the filter element compatible with strong acids like sulfuric acid or hydrochloric acid? Yes, PTFE is highly resistant to most acids, including concentrated sulfuric and hydrochloric acid, at elevated temperatures. However, always verify compatibility with your specific chemical concentration and temperature.
- Can I get custom dimensions for my existing housing? Absolutely. We offer customization of length, outer diameter, end cap types, and seal materials. Please provide your housing specifications for a tailored solution.
- What is the maximum pressure drop allowed? The initial pressure drop is low, typically less than 0.5 bar at rated flow. The maximum recommended pressure drop before cleaning is around 2.5 bar, though this can vary with application.
- Does the filter element contain any binders or adhesives? No, the construction is binder-free to avoid contamination in sensitive processes. The PTFE membrane is mechanically bonded to the fiber substrate.
- What certifications or quality standards do you follow? We operate under strict internal quality control procedures. For specific certification requirements, please contact us to discuss your needs. We can provide material test reports and performance data upon request.
