Aramid filter bags, constructed from the synthetic fiber aramid-also known as Nomex-are a hallmark in the filtration industry. Introduced by DuPont in the 1960s and commercially available since 1967, this advanced material, known in filtration circles as Meta Aramid, boasts exceptional properties. As a filtration media, aramid delivers unmatched performance with the following stellar characteristics:
Beyond these core features, aramid filter bags offer additional significant advantages, such as:
To further elevate filtration efficiency and prolong filter bag longevity, we exclusively use scrim-supported felt in our aramid filter bags. Aokai's aramid filter bags find extensive applications in sectors like asphalt, cement, and mining & metallurgy.

Q6. Do you test all your goods before delivery?
A: Yes, we perform 100% testing on all items before delivery.
Q7. How do you choose the material for a filter bag at a good price?
Each filter has unique characteristics and parameters. To select the optimal filter material for a dust collector filter bag, we assess the following criteria:
(1) Working temperature
(2) Humidity: Assess the level of moisture present to determine the optimal filter bag performance.
(3) Dust Diameter: Measure the size of dust particles to ensure effective filtration.
(4) Gas' Chemical Properties: Evaluate the chemical composition of the gas to select the appropriate filter material.
(5) Dust Abrasiveness: Consider the abrasiveness of the dust to choose a filter bag that can withstand wear and tear.
(6) Filter's Mechanical Parameters: Review the mechanical specifications to ensure compatibility with the filtration system.
Q8. When producing the filter bags, please provide the following dimensions:
(1) The diameter of the filter bags / the semi-perimeter of the filter bags: Specify exact measurements for a perfect fit.
(2) The length of the filter bags: Provide the exact length to match system requirements.
(3) The diameter and thickness of CPO on the dust collector: Detail these parameters for precise manufacturing.
(4) The drawing or sample of the filter bags: Supply detailed drawings or samples for accurate reproduction.
(5) The material of the filter bags: Indicate the material to ensure durability and compatibility.
(6) The type of filter bags: Specify whether they are round or flat, and the type of top: snap cuff or snap ring.
(7) The application of the filter bags: Indicate use cases such as cement, asphalt, power plants, chemicals, waste incineration, metallurgy, etc.
