  1. Material Composition & Properties

  - Base Materials: Specially treated polyester/polypropylene hybrid fibers with permanent anti-static properties

  - Conductive Additives: Carbon fiber threading (0.5-1.2% by weight) for consistent surface resistivity (10⁶-10⁹ Ω/sq)

  - Key Characteristics:

    ✓ Surface charge dissipation <0.1kV/sec (per ANSI/ESD S20.20)

    ✓ Filtration efficiency: 85-95% @ 0.5μm (MERV 13-15 equivalent)

    ✓ Dust holding capacity: ≥300g/m² (per ISO 16890)

    ✓ Flame retardancy: UL94 V-2 rated

  2. Performance Advantages

  - Electrostatic Protection:

    - Prevents spark generation (<3mJ ignition energy)

    - Meets ATEX Directive 2014/34/EU for explosive environments

  - Enhanced Filtration:

    - Three-layer gradient density structure

    - Particle capture down to 0.3μm @ 90% efficiency

  - Operational Economy:

    - Washable up to 50 cycles (with <15% efficiency loss per wash)

    - 40% longer service life vs conventional filters
