I. Definition & Core Functions
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.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℃.
