Key Performance Advantages
Firstly, high filtration efficiency
The dense felt structure enables effective capture of fine particles, thereby ensuring excellent particle retention and stable filtration performance.
Secondly, high temperature and flame resistance
In addition, aramid filter bags offer outstanding thermal resistance, with continuous operating temperatures up to 204 °C (400 °F). Furthermore, they are inherently flame retardant and self-extinguishing, which ensures safe operation in high-temperature environments.
Thirdly, chemical resistance
The filter media demonstrates good resistance to a wide range of chemicals, including acids, alkalis, and solvents, thus making it suitable for demanding industrial applications.
Fourthly, high strength and durability
Moreover, aramid fibers provide exceptional tensile strength, resulting in strong resistance to tearing, bursting, and abrasion, therefore ensuring reliable performance under harsh operating conditions.
Finally, low thermal shrinkage
The filter bags maintain dimensional stability when exposed to elevated temperatures, which means minimal shrinkage even during long-term high-temperature operation.
