Aramid filter bags are crafted from a high-performance synthetic fiber known as aramid, or more popularly as Nomex. Introduced in the 1960s and commercially available since 1967 by DuPont, this fiber is recognized in filtration circles as Meta Aramid. It serves as an outstanding filtration media, embodying several notable characteristics:
Beyond these filtration qualities, aramid filter bags boast additional benefits, including:
To amplify filtration efficiency and extend the lifespan of our aramid filter bags, we exclusively use scrim-supported felt in their manufacture. Aokai aramid filter bags find widespread application in industries such as asphalt, cement, and mining & metallurgy.

Q7. How do you select the right material for filter bags at a good price?
As each filter has unique features and parameters, it's crucial to consider the following when choosing filter material for dust collector filter bags:
(1) Working temperature
(2) Humidity
(3) Dust diameter - Understanding and specifying the diameter of dust particles is crucial for ensuring optimal filtration and performance of our Efficient Aramid Dust Collector Filter Cartridge Solution.
(4) Gas' chemical properties - It's imperative to consider the chemical composition and properties of the gas being filtered to select the most compatible and effective filter media.
(5) Dust abrasiveness - Identifying the abrasiveness of the dust will help in choosing the most durable and wear-resistant filter material.
(6) Filter's mechanical parameters - Detailed mechanical specifications of the filter, including tensile strength and flexibility, are necessary for tailoring the perfect filtration solution.
Q8. When producing the filter bags, please provide the following size details to ensure a perfect fit:
(1) The diameter or semi-perimeter of the filter bags - Accurate measurements are essential for seamless integration into your filtration system.
(2) The length of the filter bags - Precise length specifications are critical for achieving optimal filtration efficiency.
(3) The diameter and thickness of CPO on the dust collector - Providing these dimensions ensures that the filter bags will fit perfectly and function effectively within your dust collection system.
(4) The drawing or sample of the filter bags - A detailed drawing or physical sample will help us manufacture the filter bags to your exact requirements.
(5) The material of the filter bags - Specifying the correct filter material is vital for achieving the desired filtration performance and durability.
(6) The type of filter bags (round or flat) and the type of the filter bag top (snap cuff or snap ring) - This information is crucial for ensuring compatibility and ease of installation.
(7) The application of the filter bags - Whether for cement, asphalt, power plants, chemical industries, waste incineration, metallurgy, etc., specifying the application helps in selecting the most suitable filter bag.
