High-Performance Industrial Filter Bags by Xiechang®

The filter bag is the frontline barrier of your dust collection system. Xiechang® provides premium-grade filter bags engineered to capture fine particulates while maintaining optimal airflow. Our filter media are sourced and manufactured to ensure high filtration efficiency (up to 99.9%) and long-term durability, even in the most demanding industrial environments.

Whether you are dealing with high-temperature flue gases or abrasive dust, Xiechang® offers a comprehensive range of materials—including Nomex (Aramid), PPS, PTFE, and Glass Fiber—tailored to meet your specific emission standards and operational requirements. By combining our bags with Xiechang® cages and pulse valves, you ensure a perfectly synchronized cleaning cycle that maximizes bag life.

Key Benefits of Xiechang® Filter Media

• Precision Fit: Custom-sized to eliminate air bypass, ensuring all dust-laden gas passes through the filtration media.

• Thermal Stability: Specialized high-temp series designed to operate continuously at temperatures up to 260°C (500°F).

• Advanced Surface Treatments: Options for PTFE membrane, water & oil repellent, and anti-static finishes to prevent bag blinding and cake buildup.

• Mechanical Strength: Reinforced stitching and heavy-duty top/bottom configurations to withstand frequent high-pressure pulse cleaning.

Engineered for Critical Industries

Our filter bags are the trusted choice for Asphalt Mixing Plants, Cement Kilns, Steel Smelting, and Power Generation. By choosing Xiechang®, you benefit from 30+ years of expertise in air filtration, ensuring your plant stays compliant with global environmental regulations while minimizing replacement frequency.

Technical FAQs: Industrial Filter Bags

Q: How do I choose the right filter material for an Asphalt Plant? Asphalt plants typically generate high-temperature (150°C - 200°C) and often humid exhaust gases. Xiechang® recommends Nomex (Aramid) or PTFE-coated media for these conditions. Nomex provides excellent thermal stability and abrasion resistance, while a PTFE finish helps prevent the "sticky" dust from adhering to the bags.

Q: What is "Bag Blinding" and how can it be prevented? Bag blinding occurs when dust particles become embedded in the filter media pores rather than forming a cake on the surface, causing a sharp rise in pressure drop. Using Xiechang® bags with a PTFE membrane or oleophobic (oil-resistant) treatment significantly reduces blinding, especially in environments with high moisture or hydrocarbon content.

Q: How often should I replace my filter bags? Lifespan varies by application, but typical industrial bags last 1 to 3 years. Signs that replacement is needed include a consistently high differential pressure, visible dust emissions from the stack (leaking bags), or brittle fabric due to chemical/thermal degradation. Using a genuine Xiechang® pulse valve system can extend this lifespan by providing gentler, more effective cleaning.

Q: Can Xiechang® provide custom-shaped bags for non-standard housings? Yes. Our Suzhou manufacturing facility can produce bags in various configurations: Snap-band tops, Flange tops, Ring tops, or Envelope shapes. We provide precise OEM replacements or custom engineering based on your existing baghouse dimensions.
