Fiberglass Filter Bags

Leading Dust Filter Bag Manufacturers & Suppliers in China

Fiberglass filter bags are high-performance solutions for extreme industrial heat, offering a cost-effective balance between thermal endurance and filtration efficiency. Specifically engineered for environments up to 240°C, they are the industry standard for cement and steel emission control.
  • Extreme Heat Resistance: Continuous operation at 240°C with spikes up to 280°C.
  • Zero Shrinkage: Exceptional dimensional stability ensures no stretching or deformation under heat.
  • Chemical Fortitude: High resistance to acids and solvents in high-sulfur flue gas.
  • Ultra-Low Emissions: 99.9%+ efficiency when paired with PTFE membrane technology.
  • Fiberglass Filter Bags

    PRODUCT DESCRIPTION

    Advanced Material Engineering Our fiberglass filter bags are constructed using high-density Woven Fiberglass or Fiberglass Needle Felt. Because raw glass fiber is naturally brittle, we utilize a sophisticated multi-stage finishing process. This involves treating the media with PTFE (Teflon) impregnation or acid-resistant coatings to lubricate the fibers, preventing self-abrasion and significantly extending the mechanical life of the bag.

    Surface Technology & Performance To meet modern environmental standards, we specialize in PTFE Membrane Lamination. This “surface filtration” technology ensures that dust particles are captured on the outermost layer rather than embedding deep within the felt. The result is a smooth, non-stick surface that facilitates effortless dust cake release during pulse-jet cleaning, maintaining lower differential pressure and reducing energy consumption for your fan systems.

    Technical Specifications

    • Weight Range: Standard 750g/m² to heavy-duty 950g/m² options.

    • Thickness: Precision-engineered between 1.8mm and 3.0mm.

    • Custom Treatments: Available with Graphite, Silicon Oil, or PTFE finishes to suit specific moisture or chemical loads.

    Industrial Applications These bags are the “workhorse” of heavy industry. In Cement Plants, they handle the intense heat of kiln ends and clinker coolers. In Steel & Metallurgy, they are essential for blast furnace gas cleaning. They are also increasingly utilized in Biomass Power and Waste-to-Energy plants where complex flue gas chemistry requires a robust, non-reactive filtering media.
