1. Superior High-Temperature Resistance
-
Continuous operating temperature: Up to 200°C, with short-term resistance up to 240°C, making it ideal for high-temperature flue gas filtration (e.g., coal-fired boilers, metallurgical industries).
-
Excellent thermal stability: Aramid fiber maintains high mechanical strength and dimensional stability under extreme heat, preventing filter failure due to shrinkage or deformation.
2. Outstanding Chemical Resistance
-
Highly resistant to most acids, alkalis, and organic solvents, suitable for chemical processing, pharmaceutical industries, and other corrosive gas filtration applications.
-
Performs better than standard polyester or PPS filter bags in highly acidic or alkaline environments.
3. High Strength & Abrasion Resistance
-
Aramid fiber exhibits exceptional tensile strength and wear resistance, making it ideal for high-dust, high-velocity airflow conditions such as cement plants, steel mills, and slag processing.
-
Longer service life compared to conventional needle-felt filter bags, reducing replacement frequency and operational costs.
4. Excellent Filtration Efficiency
-
High filtration precision, capturing 99.99%+ of particulate matter, compliant with PM2.5 and PM10 emission standards.
-
Suitable for baghouse filters and pulse-jet dust collectors, effectively reducing industrial emissions.
Aramid Filter Bags are widely used in:
✅ Power Generation: Coal-fired power plants, biomass boilers
✅ Cement Industry: Kiln inlet/outlet, coal mill dust collection
✅ Steel & Metallurgy: Blast furnace gas, sintering machine emissions
✅ Chemical Processing: Sulfuric acid, fertilizer, pesticide production
✅ Waste Incineration: High-temperature flue gas filtration
✅ Mining & Mineral Processing: Dust control in coal, ore, and mineral handling
Pre-Installation: Inspect for damage; avoid contact with sharp objects.
Operation: Ensure flue gas temperature does not exceed 220°C; avoid thermal shock.
Chemical Exposure: Evaluate material compatibility if strong oxidizers (e.g., NOx, ozone) are present.
Cleaning: Use low-pressure pulse-jet cleaning to prevent mechanical damage.
