Anping County Boli Hardware Wiremesh Products Factory, established in 1998, proudly presents our premium Polypropylene Filter Sleeves for Disc Vacuum Filters — a high-performance filtration solution engineered for solid-liquid separation in demanding industrial environments. With a weight of 200g/m² and a standard length of 1.5m, these sleeves offer a balanced combination of durability and filtration efficiency, making them an ideal choice for mining, chemical, and wastewater treatment applications. Our decades of manufacturing experience ensure consistent quality, and our export volume of US$5 million to US$10 million annually across global markets reflects the trust our customers place in our products.
Each sleeve is manufactured from 100% virgin polypropylene fiber, needle-punched and thermally bonded to create a uniform, high-porosity medium. This structure provides excellent cake release properties and minimizes blinding, ensuring long service life and reduced downtime. The 200g/m² grammage delivers a robust fabric that maintains its shape under vacuum pressure while allowing optimal flow rates. The 1.5m length is designed to fit standard disc vacuum filter sectors, but custom lengths are available upon request to meet specific machine requirements.
Key Features & Technical Specifications
