Hydrolysis-Resistant, Medium-Temperature Dust Collector Media
The Acrylic Filter Bag (AFB Series) is an industrial dust filtration media manufactured from homopolymer polyacrylonitrile fiber. Positioned perfectly for medium-temperature applications (operating continuously at 125°C to 140°C), its defining advantage is its exceptional resistance to hydrolysis. Where standard polyester bags rapidly degrade in humid, moisture-heavy exhaust, acrylic fibers maintain their tensile strength and dimensional stability. This makes the AFB Series the most cost-effective choice for asphalt mixing plants, fertilizer production, and waste incineration facilities where the exhaust carries both moisture and mild acidity.
Featured Model Configurations
AFB-200 | Cement & Milling Bag
Airflow Permeability: 50 L/m²/s | Surface Treatment: Waterproof
The standard choice for cement industry applications where exhaust streams contain moderate moisture that would clump on untreated bags.
AFB-700 | Fertilizer Plant Exhaust
Airflow Permeability: 45 L/m²/s | Surface Treatment: Anti-Static
Designed with anti-static properties to safely handle the explosive dust risks sometimes present in agricultural and fertilizer milling.
Key Technical Specifications
500±10 g/m² homopolymer polyacrylonitrile needle felt with a thickness of 1.8–1.9 mm. Thermally stabilized to keep shrinkage below 2% at 135°C.High tensile strength (Warp >1200 N, Weft >1400 N) ensures the bag withstands heavy dust loads and aggressive pulse-jet cleaning cycles. Achieves up to 99% filtration efficiency with an air permeability tuned between 40 and 70 L/m²/s (@200Pa), depending on the specific model and surface treatment.
Why choosing Acrylic Filter Bag?
Superior Hydrolysis & Moisture Resistance: Made from homopolymer polyacrylonitrile fibers, preventing structural breakdown and dust blinding in high-humidity gas streams where polyester quickly degrades.
Cost-Effective Mid-Temp Solution: Delivers reliable thermal performance up to 140°C continuous (160°C peak), filling the gap between low-temp polyester (110°C ceiling) and Nomex without paying a premium for meta-aramid media.
Acid & Alkali Protection: Specialized chemical surface treatments (waterproof, oil-repellent, acid-proof) resist chemical attack from mild acidic vapors in fertilizer, cement, and chemical plants.
High Mechanical Durability: High tensile strength (>1200 N vertical, >1400 N weft) combined with low thermal shrinkage (<2%) ensures long bag life under continuous pulse-jet cleaning cycles.
Balanced Airflow & Efficiency: Achieves up to 99% filtration efficiency while maintaining steady air permeability (40–70 L/m²/s) to keep pressure drop low and minimize fan energy consumption.
