Product Features & Advantages
- Triangular Shape Design: Increases effective filtration area by up to 30% compared to standard round bags, improving dust collection efficiency and reducing cleaning frequency.
- Needle Felt Fabric: Made from high-quality polyester, polypropylene, or Nomex fibers (customizable), offering excellent tensile strength, abrasion resistance, and chemical stability.
- High-Precision Filtration: Microporous structure captures fine particles down to 1–5 microns, suitable for demanding applications like cement plants, steel mills, and chemical processing.
- Temperature Tolerant: Standard bags operate continuously up to 150°C; high-temperature variants (e.g., Nomex) can withstand 220°C or more upon request.
- Easy Installation & Maintenance: Triangular shape aligns with cage supports, minimizing bag wear and extending service life. Simple to replace without special tools.
- Standard Compliance: Each bag is tested and supplied with a Mill Test Report confirming dimensional accuracy, filtration performance, and material properties.
