Aramid filter bags, crafted from the high-performance synthetic fiber aramid-also known as Nomex-were first introduced by DuPont in 1967. This fiber, often referred to in filtration applications as Meta Aramid, boasts a remarkable history since its development in the 1960s. As a filtration medium, aramid filter bags exhibit the following outstanding characteristics:
In addition to these filtration benefits, aramid filter bags provide several other advantages, including:
- Prolonged Filter Bag Service Life
- Superior Cleaning Efficiency
- Reduced Energy Consumption
-
Eco-Friendly Design
Our aramid filter bags utilize scrim-supported felt exclusively, enhancing filtration efficiency and extending the lifespan of the filter bags. Aokai aramid filter bags are extensively employed in the asphalt, cement, mining, and metallurgy industries.

Q7. How to choose the right material for a filter bag at a good price?
Every filter has unique characteristics and parameters. To select the right material for a dust collector filter bag, consider the following factors:
(1) Operating Temperature
(2) Humidity Levels
(3) Dust Diameter: Understanding the particle size of dust is crucial for optimal filtration.
(4) Gas' Chemical Properties: Analyzing the gas's chemical composition ensures the filter material resists corrosion and degradation.
(5) Dust Abrasiveness: Evaluating the abrasiveness of dust particles helps in selecting durable filter materials.
(6) Filter's Mechanical Parameters: Assessing mechanical parameters guarantees the filter's structural integrity and performance.
Q8. When producing the filter bags, please provide the following dimensions:
(1) The diameter or semi-perimeter of the filter bags
(2) The length of the filter bags
(3) The diameter and thickness of the CPO on the dust collector
(4) A drawing or a sample of the filter bags for precise production
(5) The material composition of the filter bags
(6) The type of filter bags: round or flat, and the top type: snap cuff or snap ring
(7) The application areas of the filter bags: cement, asphalt, power plants, chemical industries, waste incineration, metallurgy, etc.
