Anping County Boli Hardware Wiremesh Products Factory, established in 1998, is a professional manufacturer specializing in filtration products. With an annual export value of US$5 million to US$10 million and a global market reach covering North America, South America, Europe, Asia, Africa, and Oceania, we are committed to delivering reliable filtration solutions. Our Industrial High Filtration Efficiency Polyester Dust Filter Cartridge with Inner Metal Mesh 33-2 combines advanced polyester media with a robust inner metal support mesh, ensuring long service life and consistent performance in demanding dust collection systems.
This filter cartridge is designed for high-efficiency dust removal in industrial environments such as cement plants, food processing, pharmaceutical facilities, and metalworking workshops. The polyester material offers excellent resistance to moisture, chemicals, and abrasion, while the inner metal mesh provides structural integrity and prevents collapse under high differential pressure. Whether you need to capture fine powder or coarse dust, this cartridge delivers reliable filtration with minimal pressure drop.
Below we detail the key features, technical specifications, and benefits that make this filter cartridge a preferred choice for many industrial applications.
Key Features
- High Filtration Efficiency: Achieves up to 99.9% filtration efficiency for particles down to 1 micron (tested according to ISO 16890).
- Polyester Media: Resistant to moisture, mold, and most chemicals; suitable for humid or oily environments.
- Inner Metal Mesh Reinforcement: Galvanized steel or stainless steel mesh (optional) prevents deformation and extends cartridge life.
- Standard 33-inch Length: Compatible with most industrial dust collector systems; custom lengths available upon request.
- Low Pressure Drop: Optimized pleat design reduces energy consumption of the fan system.
- Easy Installation: Available with open end or closed end, with gasket or without, to fit your existing housing.
- Wide Temperature Range: Continuous operation up to 135°C (275°F) with polyester media.
- Eco-friendly: Polyester material is recyclable and can be incinerated without harmful emissions.
