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.
