I. Definition & Core Functions

  1. ‌Basic Positioning‌
    As the primary filtration stage in HVAC or clean air systems, primary filters serve as "pre-filters," capturing dust particles ≥5μm to reduce the load on subsequent medium/high-efficiency filters and enhance overall system efficiency.

  2. ‌Key Value Propositions‌

    • ‌Equipment Protection‌: Prevents large particles from clogging ducts and damaging fans, reducing failure rates.
    • ‌Cost Optimization‌: Intercepts ~80% of coarse contaminants, significantly extending the service life of high-efficiency filters.
    • ‌Purification Foundation‌: Improves indoor air quality and provides primary protection for controlled environments (e.g., medical, electronics).

    • II. Performance Parameters

    • ‌Filtration Efficiency‌

      • EN779 Standard: ‌G1–G4‌ (ascending efficiency), e.g., G4 captures 40%-60% of ≥2μm particles.
      • Typical interception rate for ≥5μm particles: ‌35%-95%‌ (dependent on media density/structure).

    • ‌Resistance & Airflow‌

      • ‌Initial Resistance‌: 10-50Pa (G3/G4).
      • ‌Final Resistance‌: Replace when ≤250Pa.
      • ‌Rated Airflow‌: 500–5000m³/h; scales with size (e.g., 595×595mm panel: 2400m³/h).

    • ‌Dust Capacity & Durability‌

      • ‌Dust Holding Capacity‌: 100-1000g/m²; pleated/bag > panel.
      • ‌Temperature Resistance‌: Standard: -10℃~70℃; high-temp variants: 250-300℃.
