Aramid filter bags are made of a synthetic fiber material called aramid, also known as Nomex. It was first developed in the 1960s and made commercially available in 1967 by DuPont. For filtration applications, it is most often known as Meta Aramid. As a filtration media, it has the following characteristics:
-
Efficient Particle Retention - The tightly felt structure of the aramid filter media enables it to effectively capture fine particles, thereby achieving high levels of filtration efficiency.
- High Temperature & Flame Resistance - Aramid filter bags possess remarkable resistance to high temperatures without significant degradation. These aramid bags can withstand continuous operating temperatures of up to 204°C (400°F). In addition, aramid filter bags are self-extinguishing and flame retardant.
- Chemical Resistance - Aramid filter bags are resistant to a wide range of chemicals, including acids, alkalis, and solvents.
-
High Strength and Robustness - Aramid fibers have exceptional tensile strength, which makes the filter bags resistant to tearing and bursting. They can withstand the rough handling and abrasive nature of certain dust particles, resulting in enhanced durability and reliability.
- Low Thermal Shrinkage - When aramid filter bags are subjected to elevated temperatures, they demonstrate excellent stability and resistance to shrinkage. They maintain their original size and shape even after prolonged exposure to extreme heat.
In addition to these filtration characteristics, aramid filter bags also offer a number of other advantages, such as:
Scrim-supported felt is used exclusively in the production of our aramid filter bags in order to improve filtration efficiency and extend the filter bag life. Aokai aramid filter bags are widely used in asphalt, cement, and mining & metallurgy industries.

Q5.Can you produce according to the samples?
A: Yes, we can produce by your samples or technical drawings. We can build the molds and fixtures.
Q6. Do you test all your goods before delivery?
A: Yes, we have 100% test before delivery.
Q7.How to choose material for filter bag with good price ?
Since every filter has its own characteristics and parameters, when we choose filter material for dust collector filter bag, we have to know the following parameters:
(1) Working temperature
(2) Humidity
(3) Dust diameter
(4) Gas' chemical properties
(5) Dust abrasiveness
(6) Filter's mechanical parameters
Q8.When we produce the filter bags ,you need to provide the below size :
(1)The diameter of the filter bags /the semi-perimeter of the filter bags
(2)The length of the filter bags
(3)The diameter of CPO and the thickness of CPO on dust collector on dust collector
(4)The drawing of the filter bags or the sample of the bag
(5)The material of the filter bags
(6)The type of the filter bags : round or flat ,the type of the filter bag top : snap cuff or snap ring
(7)The application of the filter bags ,cement ,asphalt ,power plant , chemical ,waste incineration , metallurgy and so on.
