Dust Collector Filter Bag

Aramid filter bags are crafted from a synthetic fiber material known as aramid, recognized as Nomex in some contexts. These filter bags offer remarkable filtration capabilities and durability, with key features including:

1. Efficient Particle Retention: The tightly felted structure of aramid filter media effectively captures fine particles, ensuring high filtration efficiency.
2. High Temperature & Flame Resistance: Aramid filter bags withstand continuous operating temperatures of up to 204°C (400°F) and possess self-extinguishing and flame retardant properties, making them ideal for high-temperature applications.
3. Chemical Resistance: Resistant to a wide range of chemicals including acids, alkalis, and solvents, ensuring longevity and reliability in diverse industrial settings.
4. High Strength and Robustness: Aramid fibers boast exceptional tensile strength, rendering the filter bags resistant to tearing and bursting, even in abrasive environments.
5. Low Thermal Shrinkage: Even when subjected to elevated temperatures, aramid filter bags maintain their original size and shape, demonstrating excellent stability and resistance to shrinkage.
