Acrylic filter bags are made from polyacrylonitrile (PAN) synthetic fibers, with a gap distribution of superfine fiber cloth surface by the treatment of hot rolling, such as singeing. Its surface is smooth, and it is not easy to be blocked by dust, with a big gap. The air permeability is good, and the anti-chemical stability is strong. The acrylic dust removal bag has a rather special material. Its surface is prone to generating static electricity and easily adsorbs harmful substances such as dust in the air. Therefore, it is prone to fiber aging and damage. It is not suitable for all the working conditions.

Applications
Acrylic filter bags fill the niche between polyester and aramid fibers, offering optimal performance in humid, moderate-temperature environments at a competitive price point. Their natural resistance to hydrolysis makes them ideal for cement, biomass, and food industry applications where moisture is present. For higher temperature requirements (125°C), P84® or PTFE alternatives should be considered.
asphalt mixing industry
In the asphalt mixing industry, they are a core filtration solution for dust control in drying drums and mixing tanks. Asphalt mixing processes generate dust with temperatures ranging from 120℃ to 180℃-a range perfectly matched by the acrylic material's operating temperature limit (up to 190℃). Additionally, the dust often contains asphalt volatiles and moisture, and the acrylic filter bag's strong hydrolysis resistance prevents structural damage from humid environments, ensuring consistent filtration efficiency (over 99.5% for particles 5μm and above). This not only reduces air pollution but also prevents sticky asphalt dust from clogging the filter media, minimizing maintenance downtime for mixing plants.
grain and oil processing industry
In the grain and oil processing industry, Acrylic Filter Bags excel in dust collection during grain drying, oilseed pressing, and flour milling. During grain drying, the air stream carries dust at 100℃ to 160℃, along with high humidity from evaporated moisture-conditions where acrylic's resistance to moisture and moderate heat outperforms ordinary polyester filter bags. For example, in soybean oil processing, the filter bags trap oilseed hull dust and fine meal particles, preventing cross-contamination of the final oil product and maintaining a clean production environment. Their smooth surface also facilitates easy pulse cleaning, reducing dust accumulation and extending the bag's service life to 12–18 months, which is 20% longer than standard polyester alternatives in similar applications.
wood processing industry
The wood processing industry relies on Acrylic Filter Bags for dust removal in wood drying, sanding, and panel production. Wood processing generates a mix of sawdust, wood fiber dust, and resin particles, with process temperatures typically between 80℃ and 150℃. Acrylic's medium-temperature resistance ensures stability even during prolonged exposure to heated air streams, while its fine fiber structure captures tiny wood dust particles (as small as 3μm) that could pose fire risks or respiratory hazards. In particleboard manufacturing, the filter bags also prevent resin dust from adhering to equipment surfaces, reducing the need for frequent cleaning and improving production line efficiency. Moreover, acrylic's chemical inertness means it does not react with wood resins or preservatives, ensuring no contamination of the end product.
waste incineration auxiliary systems
In the waste incineration auxiliary systems (such as flue gas pre-treatment for low-temperature sections), Acrylic Filter Bags play a vital role in dust capture. While high-temperature flue gas from incineration requires PPS or PTFE filter bags, the pre-cooled flue gas in auxiliary systems (80℃ to 170℃) with high humidity and corrosive components (e.g., weak acids from waste decomposition) is an ideal match for acrylic's properties. The filter bags remove fly ash and unburned carbon particles from the pre-treated flue gas, reducing the load on downstream acid removal equipment and protecting it from abrasion. Their resistance to weak corrosion also ensures durability in harsh environments, avoiding premature replacement costs.
Furthermore, Acrylic Filter Bags find applications in the textile dyeing industry (for collecting fiber dust and dye particles at 90℃ to 150℃, with resistance to mild dyeing chemicals) and the chemical fertilizer industry (for filtering ammonium sulfate or urea dust in medium-temperature granulation processes, where humidity control is critical). Their balance of performance, cost-effectiveness, and adaptability to medium-temperature, humid conditions makes them a practical choice for industries seeking reliable dust removal without investing in expensive high-temperature filter technologies.
