① High porosity
Porosity up to 80%~90%, micropore structure is stable, micropore structure with fiber interleaved arrangement, through two-directional stretching process, through high temperature hot shaping treatment, micro pore structure is stable, effectively intercept dust particles
② Low resistance value
The filtration efficiency reaches 99.9999995% with high filtration efficiency, can meet the filtration efficiency level requirements of subefficient, efficient and ultra-efficiency air filter, better than other filtration materials
③ Small membrane aperture
Surface filtering mechanism, easy dust removal, small and uniform aperture, strong hydrophobic water, low surface energy, with good non-adhesion ability, effectively remove the dust accumulated on the surface, recover with water or backblowing, greatly prolong the service life
