As a leading manufacturer established in 1998, Anping County Boli Hardware Wiremesh Products Factory specializes in producing high-performance filtration solutions. Our PTFE Coated Filter Sleeves for Disc Vacuum Filters are engineered to deliver exceptional filtration efficiency and durability in demanding industrial environments. With an annual export value of US$5 Million to US$10 Million, we serve global markets including North America, Europe, and Asia, ensuring our products meet the highest standards of quality and reliability.
These filter sleeves feature a precise PTFE coating that provides superior chemical resistance and thermal stability. The 0.5 micron filtration rating captures fine particles while maintaining high flow rates, making them ideal for solid-liquid separation processes in chemical, pharmaceutical, mining, and metallurgical industries. The sleeves are designed to withstand continuous operation at temperatures up to 260°C, effectively handling hot corrosive slurries without degradation.
Key advantages of our PTFE Coated Filter Sleeves include:
- Exceptional Chemical Resistance: The PTFE coating resists attack from strong acids, alkalis, and organic solvents, extending service life in aggressive media.
- High Temperature Stability: Reliable performance up to 260°C, suitable for hot filtration processes.
- Low Friction Surfaces: Smooth PTFE surface reduces cake adhesion and facilitates easy cleaning, improving filtration cycle efficiency.
- Precise Pore Structure: 0.5μm filtration rating ensures consistent particle retention and high filtrate clarity.
- Customizable Dimensions: Available in various lengths and diameters to fit standard and custom disc vacuum filter designs.
- Durable Construction: Reinforced base fabric provides mechanical strength, preventing tearing under high pressure or vacuum conditions.

Our PTFE Coated Filter Sleeves are designed to improve the overall performance of your disc vacuum filter system. The low coefficient of friction of the PTFE coating minimizes cake blinding and reduces the need for frequent washing, increasing uptime and productivity. The sleeves are also resistant to hydrolysis and oxidation, ensuring long-term stability even in harsh chemical environments.
The product is manufactured using advanced weaving and coating technologies, ensuring uniform pore distribution and consistent quality. Each sleeve undergoes strict quality control checks, including filtration efficiency tests, temperature resistance tests, and dimensional accuracy measurements. We offer customization options to meet specific process requirements, such as different lengths, diameters, and end finishes (e.g., sewn or welded).
