Aramid filter bags, crafted from the synthetic fiber known as aramid or Nomex, were first developed in the 1960s and introduced to the market by DuPont in 1967. Recognized in filtration applications as Meta Aramid, this exceptional material boasts the following key characteristics:
In addition to their superior filtration properties, aramid filter bags also provide remarkable benefits, such as:
Our aramid filter bags are exclusively manufactured using scrim-supported felt, enhancing filtration efficiency and extending their lifespan. Widely utilized in industries such as asphalt, cement, and mining & metallurgy, Aokai aramid filter bags are synonymous with reliability and performance.
