As a leading manufacturer with over 25 years of experience in wire mesh and filter fabrics, Anping County Boli Hardware Wiremesh Products Factory proudly presents our Polypropylene Filter Cloth Sleeves for disc vacuum filters. These sleeves are engineered to deliver exceptional filtration performance in demanding industrial environments, featuring a precise 100 micron rating, high-temperature resistance up to 200°C, and outstanding acid resistance. Our sleeves are designed to maximize filtration efficiency while minimizing downtime, making them a trusted choice for global customers across various industries.
Manufactured from premium polypropylene (PP) fibers, each sleeve is woven to strict quality standards to ensure consistent pore size and mechanical strength. The 100 micron opening effectively captures fine particles while maintaining high flow rates, ideal for applications such as mineral processing, chemical filtration, wastewater treatment, and food processing. The fabric's resistance to acids and elevated temperatures ensures long service life even under harsh conditions.

Our polypropylene filter cloth sleeves are specifically designed to fit standard disc vacuum filter sectors, providing a tight seal and uniform cake formation. The surface filtration mechanism ensures easy cake discharge and minimal blinding, reducing cleaning frequency and maintenance costs. Compared to traditional filter media, our sleeves offer higher filtration efficiency, longer service life, and better resistance to thermal and chemical degradation.
Each sleeve undergoes rigorous quality control, including visual inspection, dimensional verification, and performance testing under simulated operating conditions. We guarantee consistent quality across all production batches.

Frequently Asked Questions (FAQ)
-
Q: What is the typical lifespan of these filter cloth sleeves under normal operating conditions?
A: With proper maintenance and suitable operating conditions, our polypropylene sleeves typically last 6–12 months. Actual lifespan depends on factors such as abrasive particles, chemical concentration, and cleaning frequency. We recommend periodic inspection and replacement when cake discharge becomes difficult or pressure drop increases significantly. -
Q: Can these sleeves be used for continuous operation at 200°C?
A: Yes, our polypropylene fabric is designed to withstand continuous operating temperatures up to 200°C. However, for long-term stability, we suggest keeping the temperature below 180°C when possible, as polypropylene may experience slight dimensional changes near its maximum limit. -
Q: Do you offer custom sizes for non-standard disc filter sectors?
A: Absolutely. We can produce sleeves in any size based on your drawings or existing samples. Just provide the diameter, length, and number of sectors, and we will manufacture accordingly. Custom orders typically require a minimum quantity and lead time of 2–3 weeks. -
Q: Are these sleeves resistant to strong acids like sulfuric acid or hydrochloric acid?
A: Yes, polypropylene has excellent resistance to most inorganic acids, including sulfuric acid (up to 98% concentration), hydrochloric acid, and phosphoric acid at moderate temperatures. For highly concentrated acids at elevated temperatures, we recommend testing a sample under your specific conditions. -
Q: What is the difference between plain weave and twill weave for filter cloth?
A: Plain weave provides a tighter structure with smaller pore size, suitable for fine particle retention. Twill weave offers higher flow rates and is less prone to blinding. We offer both options; the choice depends on your particle size distribution and required throughput. Our sales team can help you select the best weave. -
Q: Can I get a sample before placing a bulk order?
A: Yes, we provide free samples (up to 2 pieces) for evaluation. You only need to cover the shipping cost. Samples are manufactured to your specified dimensions, so you can test fit and performance on your actual disc vacuum filter. -
Q: How are the sleeves packaged to prevent damage during shipping?
A: Each sleeve is individually wrapped in plastic film, then packed in sturdy cartons or polypropylene woven bags. For large orders, we use palletized packaging with shrink wrap and corner protectors. We also add desiccant packs if needed. Our packaging complies with international shipping standards. -
Q: What is the minimum order quantity (MOQ)?
A: For standard sizes, the MOQ is 50 pieces. For custom sizes, the MOQ is 100 pieces. If you need a smaller quantity for trial, please contact us, and we may be able to accommodate based on stock availability.
