P84 Filter Bags

Leading Dust Filter Bag Manufacturers & Suppliers in China

P84 (Polyimide) is a high-end synthetic fiber known for its unique irregular fiber structure. Unlike round fibers, P84’s increased surface area provides maximum dust capture and superior release properties, making it the premier choice for fine particulate control in high-temperature, reactive environments.
  • Thermal Range: 240°C (constant) | 260°C (peak).
  • Trilobal Fiber: Maximum surface area for high-precision filtration.
  • Efficient Cleaning: Irregular cross-sections prevent deep dust penetration.
  • Flame Retardant: Naturally non-flammable with high dimensional stability.
  • Low Pressure Drop: Optimized airflow even under high dust loads.

    PRODUCT DESCRIPTION

    P84 provides the highest surface-to-volume ratio in the filtration industry. The unique trilobal cross-section of the fibers creates a physical barrier that traps fine dust on the surface of the felt rather than inside it. This surface-loading characteristic ensures that pulse-jet cleaning is exceptionally effective, keeping operational pressure drops at a minimum.

    Technical Advantages

    • Superior Capture Efficiency: The irregular fiber shape creates more “collection points” per square inch, allowing facilities to meet ultra-low emission targets without relying solely on membrane coatings.

    • High Thermal Stability: Maintains mechanical flexibility and structural integrity at continuous temperatures of 240°C, filling the gap where lower-grade fibers fail.

    • Chemical Durability: Excellent resistance to organic solvents and oxidation. Note: Performs best in low-moisture environments (sensitive to high concentrations of $SO_2$/$NO_x$ in the presence of steam).

    • Energy Savings: High permeability combined with easy dust release reduces the frequency of cleaning cycles, extending the service life of both the bag and the pulse valves.

    Applications

    • Waste Incineration: Effective for hazardous and municipal waste plants with high-temperature flue gas.

    • Cement Kilns: Ideal for clinker coolers and kiln ends where high heat is constant.

    • Smelting & Metal: Lead, copper, and steel smelting off-gas recovery.

    • Chemical Processing: Drying and calcining processes involving high-value fine powders.

    • Carbon Black: High-efficiency recovery in high-heat production lines.
