Aramid filter bags are crafted from a high-performance synthetic fiber known as aramid, or more famously, Nomex. Introduced by DuPont in the 1960s and making its commercial debut in 1967, it is most often referred to as Meta Aramid in filtration contexts. This premium filtration media boasts a range of impressive characteristics:
Beyond these stellar filtration attributes, aramid filter bags also provide several additional benefits:
Our aramid filter bags are exclusively manufactured using scrim-supported felt, enhancing both filtration efficiency and longevity. Aokai aramid filter bags are extensively utilized across asphalt, cement, and the mining & metallurgy sectors.

Q7. How do you choose material for a filter bag at a good price?
Since each filter has unique characteristics and parameters, selecting the right filter material for a dust collector filter bag requires the following information:
(1) Operating temperature
(2) Humidity levels
(3) Dust Diameter: A critical factor determining filtration efficiency and overall system performance.
(4) Gas' Chemical Properties: Essential for selecting materials that offer optimal resistance and longevity.
(5) Dust Abrasiveness: Vital for determining the durability and appropriate material of the filter bag.
(6) Filter's Mechanical Parameters: Key elements that define the structural integrity and operational effectiveness of the filter.
Q8. When we produce the filter bags, please provide the following size specifications:
(1) The Diameter or Semi-Perimeter of the Filter Bags: Crucial for ensuring a precise fit and efficient filtration.
(2) The Length of the Filter Bags: Important for achieving the desired filtration capacity and compatibility.
(3) The Diameter and Thickness of CPO on the Dust Collector: Necessary for proper integration and performance.
(4) The Drawing or Sample of the Filter Bags: Helps in ensuring accurate manufacturing to your exact specifications.
(5) The Material of the Filter Bags: Determines the filter's efficiency, durability, and suitability for different applications.
(6) The Type of the Filter Bags: Round or Flat, and the Type of Filter Bag Top: Snap Cuff or Snap Ring, crucial for fitting and application purposes.
(7) The Application of the Filter Bags: Specify industries such as cement, asphalt, power plant, chemical, waste incineration, metallurgy, etc., to tailor the bag to specific needs.
