Aramid filter bags, crafted from the synthetic fiber aramid (also known as Nomex), were first introduced in the 1960s and became commercially available in 1967 by DuPont. Recognized in filtration applications as Meta Aramid, this material boasts the following standout characteristics:
Beyond their superior filtration qualities, aramid filter bags also present numerous other benefits, including:
- Prolonged Filter Bag Service Life
- Enhanced Cleaning Efficiency
- Reduced Energy Consumption
-
Eco-Friendly Design
Utilizing scrim-supported felt exclusively in our aramid filter bags enhances filtration efficiency and extends the lifespan of the bags. Aokai aramid filter bags are extensively applied in the asphalt, cement, and mining & metallurgy industries.
