Aramid filter bags, crafted from the innovative synthetic fiber known as aramid or Nomex, were first unveiled in the 1960s and made commercially available by DuPont in 1967. Renowned in filtration applications as Meta Aramid, this material offers exceptional properties that make it a superior choice for filtration needs. Here are the remarkable characteristics of aramid filter bags:
Beyond these core filtration benefits, aramid filter bags also offer numerous additional advantages that include:
Our aramid filter bags utilize scrim-supported felt exclusively, enhancing filtration efficiency and extending the lifespan of the bags. These bags find extensive applications in industries such as asphalt, cement, and mining & metallurgy due to their reliability and performance.
