Aramid filter bags are manufactured from a synthetic fiber known as aramid, or Nomex. Initially developed in the 1960s and made commercially available by DuPont in 1967, it is primarily recognized as Meta Aramid in filtration contexts. As a filtration medium, it boasts the following exceptional characteristics:
Beyond these remarkable filtration properties, aramid filter bags bring numerous other advantages, such as:
Our aramid filter bags are exclusively crafted using scrim-supported felt, enhancing filtration efficiency and prolonging filter bag lifespan. Aokai's aramid filter bags are extensively utilized in industries such as asphalt, cement, and mining & metallurgy.
