1. Air Filtration Technologies
1.1 HEPA Filtration Technology
Filtration Mechanism:
-
Interception: Particles adhere to fiber surfaces
-
Impaction: Larger particles embed in filter fibers
-
Diffusion: Submicron particles collide with gas molecules
Performance Characteristics:
-
Minimum 99.97% efficiency at 0.3 microns
-
Low airflow resistance design
-
Compliant with EN 1822 and IEST-RP-CC001 standards
1.2 Alternative Filtration Media
Activated Carbon:
-
Adsorbs gaseous pollutants and odors
-
Surface area typically 500-1500 m²/g
-
Complementary to particulate filtration
Electret Media:
-
Electrostatically charged fibers
-
Enhanced initial filtration efficiency
-
Gradual charge dissipation over time
