Performance of Polyester Filter Cloth
(1) Resist strong acid and weak alkali.
(2) It’s stable to thick abioacid in low temperature,not dissolved in organic acid, but can be dissolved in thick vitriol and heated cresol.
(3) It’s easily hydrolyzed in strong alkali.
Applications of Polyester Filter Cloth
Dust collector or liquid-solid separation. Mainly used in food and beverage industry, pharmaceutical industry, non-ferrous metallurgy, chemical plant, building section,mining industry,etc., for the equipment of filter presses, centrifuge filters, vacuum filters, belt filter presses, etc.
High Strength and Durability
The seamless filter cloth features a robust structure capable of withstanding high pressure and frequent pulse-jet cleaning cycles without sustaining damage. Its high tensile strength ensures a long service life under harsh operating conditions, thereby reducing replacement frequency and maintenance costs.
Ease of Cleaning
The surface of the seamless filter cloth material is smooth, facilitating easy and thorough cleaning via pulse-jet backflushing. Backflushing is a commonly employed cleaning method in dust collection systems; it rapidly and effectively removes dust particles adhering to the filter cloth surface, thereby restoring the cloth’s filtration performance.
Strong Adaptability
The seamless filter cloth is highly adaptable to a wide range of operating conditions. Available in various filtration materials, it delivers exceptional performance in diverse environments—whether involving high temperatures, corrosive substances, or high humidity levels. Consequently, it possesses broad applicability across a wide spectrum of industrial dust collection applications.
Customizability
Based on specific client requirements, the W-series seamless filter cloth can be customized in terms of size and filtration precision to meet the distinct demands of various dust collection equipment and industrial processes. This inherent flexibility ensures its effective integration and application within a wide variety of dust collection systems.
