Aramid filter bags are crafted from the advanced synthetic fiber material, aramid, popularly known as Nomex. This innovative material, first developed in the 1960s and commercially launched by DuPont in 1967, is recognized as Meta Aramid in filtration applications. As a superior filtration media, it boasts the following exceptional characteristics:
Beyond its outstanding filtration properties, aramid filter bags provide additional key benefits, including:
Exclusively using scrim-supported felt, our aramid filter bags significantly improve filtration efficiency and prolong their service life. Aokai aramid filter bags are the preferred choice in the asphalt, cement, and mining & metallurgy industries.
