DustPPS filter bags are medium-to-high-temperature dust collector filter bags made primarily from polyphenylene sulfide (PPS) fiber through a non-woven needle-punching process. They offer excellent hydrolysis resistance, high temperature resistance, and corrosion resistance, enabling stable operation at temperatures up to 190 °C. They are suitable for dust removal in sulfur-containing flue gases in applications such as thermal power generation, waste incineration, and the chemical industry.
We offer a variety of post-treatment options, including membrane lamination, anti-static treatment, and oil- and water-repellent finishes, providing flexible customization services to meet diverse customer requirements.
The dust collector filter bag primarily consists of a bag opening, bag body, and bag bottom. The bag body is made from fibers through a needle-punch nonwoven process, forming a three-layer structure: fiber layer – base fabric – fiber layer.
When dust-laden airflow passes through the filter bag, dust is retained on the outer surface of the filter bag (surface filtration) or within the filter material (depth filtration), while clean air passes through the medium and is discharged through the outlet.
