Acrylic Filter Bag
Acrylic Filter Bags (also known as Polyester-Acrylic Filter Bags) are high-performance industrial filtration solutions designed for moderate-temperature dust collection in various industries. Made from acrylic fiber (PMMA), these filter bags offer excellent chemical resistance, moisture control, and long service life, making them ideal for cement plants, woodworking, food processing, and pharmaceutical dust collection.

✔ Moderate Heat Resistance – Continuous operating temperature up to 120°C (248°F), with short-term peaks at 140°C (284°F).
✔ Superior Moisture & Hydrolysis Resistance – Performs well in humid environments where polyester bags may degrade.
✔ Excellent Chemical Resistance – Handles weak acids, alkalis, and organic solvents better than standard polyester filter media.
✔ High Filtration Efficiency – Captures fine dust particles (PM2.5, PM10) with >99.5% efficiency, improving air quality and compliance with EPA, ISO, and industrial emission standards.
✔ Longer Lifespan – More durable than standard polyester bags, reducing replacement frequency and maintenance costs.
✔ Customizable Options – Available in standard sizes (φ120mm to φ200mm), with flange, snap ring, or cuff closures for easy installation in baghouse dust collectors, pulse-jet systems, and shaker filters.
Acrylic filter bags are widely used in industries requiring moderate-temperature dust control, including:
✅ Cement & Asphalt Plants – Kiln feed, clinker cooler, and raw mill dust collection
✅ Woodworking & Furniture Manufacturing – Sawdust, sanding dust, and MDF particle filtration
✅ Food & Pharmaceutical Processing – Flour, sugar, starch, and powder handling
✅ Coal & Biomass Power Plants – Boiler baghouse filtration
✅ Chemical & Mineral Processing – Non-corrosive dust collection

Why Choose Acrylic Over Other Filter Bags?
🔹 Better than Polyester – More resistant to moisture and hydrolysis, ideal for humid conditions.
🔹 Cost-Effective Alternative to Nomex/PPS – Performs well in moderate heat without the high cost of aramid or PTFE bags.
🔹 Anti-Static Options Available – Reduces explosion risks in wood dust, coal, and flammable powder applications.
While they resist moisture, a PTFE membrane-coated version is better for oily or sticky particles.
They last longer in humid and slightly acidic/alkaline environments but have similar temperature limits.
Yes, with anti-static treatment, they can be used in ATEX-compliant dust collection systems.
