Aramid filter bags are meticulously crafted from a high-performance synthetic fiber known as aramid, widely recognized under the brand name Nomex. First introduced in the 1960s and made commercially available by DuPont in 1967, this material is often referred to as Meta Aramid in filtration applications. With exceptional properties, it serves as an outstanding filtration media, characterized by the following features:
Beyond these filtration characteristics, aramid filter bags offer a suite of additional advantages, including:
Our aramid filter bags are exclusively manufactured using scrim-supported felt, enhancing filtration efficiency and prolonging filter bag longevity. Aokai aramid filter bags are widely deployed in demanding industries such as asphalt, cement, and mining & metallurgy.

Q7. How do you choose the right filter bag material at a good price?
Given that each filter possesses unique characteristics and parameters, choosing the correct filter material for a dust collector filter bag requires knowledge of the following parameters:
(1) Working Temperature
(2) Humidity
(3) Dust diameter: Ensure precision by detailing the exact measurements of dust particles.
(4) Gas' chemical properties: Specify the composition and characteristics of the gas to ensure optimal filter performance.
(5) Dust abrasiveness: Describe the level of abrasiveness to select appropriate filter materials that resist wear and tear.
(6) Filter's mechanical parameters: Provide the comprehensive mechanical specifications for the filter to ensure compatibility and efficiency.
Q8. To produce the perfect filter bags, please provide the following precise dimensions:
(1) Diameter of the filter bags/semi-perimeter: Indicate the exact diameter or semi-perimeter to guarantee a perfect fit.
(2) Length of the filter bags: Provide the total length for accurate production.
(3) Diameter and thickness of CPO on the dust collector: Specify both the diameter and thickness to ensure seamless integration with your dust collector.
(4) Drawing or sample of the filter bags: Supply a detailed drawing or a sample to ensure precise manufacturing.
(5) Material of the filter bags: Identify the specific material required for the filter bags to meet your operational needs.
(6) Type of filter bags: round or flat, and the filter bag top: snap cuff or snap ring: Clarify the type and top design to tailor to your exact requirements.
(7) Application of the filter bags: Provide context on the application environment such as cement, asphalt, power plant, chemical, waste incineration, metallurgy, and more for customized solutions.
