Welcome to Anping County Boli Hardware Wiremesh Products Factory! Since 1998, we have been a trusted manufacturer of filtration solutions, exporting to over 15 markets worldwide with annual exports of US$5–10 million. Our PTFE Coated Filter Cloth Bags for Disc Vacuum Filters are engineered to deliver superior filtration performance in demanding industrial environments. Combining a precise 0.5μm filtration efficiency with high-temperature resistance up to 260°C, these bags offer a non-stick surface for easy cake release and an optional anti-static feature for safety. Whether you are in mining, chemical processing, or wastewater treatment, our filter bags are designed to maximize your production uptime and reduce maintenance costs.
Key Features & Technical Specifications
- PTFE Coating Technology: The advanced PTFE coating forms a smooth, non-stick surface that prevents particle adhesion, ensuring efficient cake discharge and minimal blinding.
- 0.5μm Filtration Efficiency: Captures fine particles down to 0.5 microns, ideal for applications requiring high clarity filtrate.
- 260°C High Temperature Resistance: Withstands continuous operation at elevated temperatures, perfect for hot process streams.
- Anti-Static Option (Conductive Fibers): Optional integrated conductive fibers dissipate static charges, reducing fire risk in combustible dust environments.
- Customizable Dimensions: Available in various sizes and shapes to fit standard disc vacuum filters (e.g., 0.5m, 1.0m, 1.5m diameter discs).
- High Mechanical Strength: Reinforced base fabric (polyester or blended) provides excellent tear and abrasion resistance for long service life.

Applications & Benefits
- Mining & Metallurgy: Efficient dewatering of mineral concentrates, tailings, and slurry filtration.
- Chemical & Petrochemical: Filtration of hot chemicals, catalysts, and fine powder recovery.
- Wastewater Treatment: Sludge dewatering in municipal and industrial plants.
- Food & Beverage: Filtration of edible oils, starch, and sugar solutions where hygiene is critical.
- Benefits for Your Operation: Reduced downtime for bag changes, lower energy consumption due to low pressure drop, and improved product quality from consistent filtrate clarity.
Our PTFE coated bags are designed to fit disc vacuum filters from major OEMs (e.g., Eimco, Peterson, Komline-Sanderson) and can be customized to match your specific disc dimensions. The non-stick PTFE surface minimizes cake sticking, allowing faster filter cycles and easier cleaning. The optional anti-static version adds an extra layer of safety in explosive environments, such as coal dust or metal powder handling.

Frequently Asked Questions
-
Q: What is the maximum temperature these bags can withstand?
A: Our PTFE coated filter cloth bags operate continuously at 260°C. For intermittent peaks, please consult our technical team as performance may vary based on the specific substrate. -
Q: Can the anti-static feature be added to all sizes?
A: Yes, the anti-static option (conductive fibers) is available for any size and shape. Please specify when ordering to ensure correct integration. -
Q: How does the non-stick surface benefit the filtration process?
A: The non-stick PTFE coating prevents cake adhesion, allowing complete cake discharge. This reduces cleaning time, minimizes blinding, and extends bag life, ultimately lowering your overall filtration cost. -
Q: What is the typical lifespan of these filter bags?
A: Lifespan depends on operating conditions (temperature, chemical exposure, abrasiveness). In many applications, our bags last 2–5 times longer than standard polyester bags due to the PTFE coating and robust base fabric. -
Q: Do you offer samples for testing?
A: Yes, we provide sample swatches or small trial bags. Contact our sales team with your disc dimensions and process parameters to arrange a sample. -
Q: Can the filtration efficiency be customized to other micron ratings?
A: Absolutely. While 0.5μm is our standard, we can produce bags with ratings from 0.2μm to 100μm. Please inquire for custom requirements. -
Q: What is the lead time for bulk orders?
A: Typical lead time is 15–25 working days after order confirmation, depending on quantity and customization. We can expedite urgent orders upon request. -
Q: How do I ensure the bags fit my disc vacuum filter correctly?
A: Provide your disc diameter, bag shape (round/flat), and any special cutouts. We can also work from a drawing or template. Our team will verify dimensions before production.
