Aramid filter bags, crafted from the synthetic fiber known as aramid or Nomex, were first developed in the 1960s and commercialized by DuPont in 1967. Recognized in filtration applications as Meta Aramid, this material stands out for its superior filtration properties, including:
Beyond these filtration attributes, aramid filter bags provide additional benefits, such as:
- Prolonged Filter Bag Service Life
- Improved Cleaning Efficiency
- Reduced Energy Consumption
-
Eco-Friendly Performance
Our aramid filter bags, exclusively made with scrim-supported felt, are engineered to enhance filtration efficiency and longevity. Aokai aramid filter bags are extensively utilized in asphalt, cement, and mining & metallurgy sectors.

Q6. Do you test all your products before delivery?
A: Absolutely, we conduct 100% testing before delivery.
Q7. How do you choose the right material for filter bags at a good price?
Each filter has unique characteristics and parameters. To select the proper filter material for a dust collector filter bag, consider the following factors:
(1) Operating Temperature
(2) Humidity Levels
(3) Dust Diameter: Understanding the precise diameter of the dust particles is essential for the optimal performance of our China-Origin Durable Collector Filter Bag Solution.
(4) Chemical Properties of Gas: Identifying the chemical composition of the gas ensures that the filter bag can withstand the operational environment, thus enhancing durability and efficiency.
(5) Dust Abrasiveness: Knowing the abrasiveness level of the dust particles allows us to tailor the filter bag material to prevent premature wear and extend its lifespan.
(6) Filter's Mechanical Parameters: The mechanical specifications of the filter, such as tensile strength and flexibility, play a key role in ensuring reliable performance in demanding conditions.
Q8. When producing the filter bags, please provide the following dimensions:
(1) Diameter/Semi-Perimeter of Filter Bags: Precise measurements of the diameter or semi-perimeter of the filter bags are crucial for a perfect fit and optimal filtration efficiency.
(2) Length of Filter Bags: Accurate length measurements are necessary to ensure that the filter bags perform effectively within the dust collection system.
(3) Diameter and Thickness of CPO on Dust Collector: Please specify the exact diameter and thickness of the CPO to ensure compatibility and effective dust collection.
(4) Filter Bag Drawing or Sample: Providing a detailed drawing or a physical sample of the filter bag will help us deliver a product that matches your exact requirements.
(5) Material of Filter Bags: Indicate the preferred material for the filter bags to ensure they meet the specific needs of your application.
(6) Type of Filter Bags and Tops: Specify whether the filter bags should be round or flat, and the type of top-snap cuff or snap ring-for optimal installation and performance.
(7) Application of Filter Bags: Please state the intended use, whether it's for cement, asphalt, power plants, chemical facilities, waste incineration, metallurgy, etc., to ensure the filter bags are designed for maximum efficiency and longevity.
