Polyester filter bag is widely used in industrial filtration component made from high-strength, synthetic polyester fibers. It is designed to capture and remove dust, particulates, and contaminants from air in various industrial applications.
Polyester filter bags are known for their excellent chemical resistance, durability, and cost-effectiveness, making them a popular choice in sectors such as cement, steel, pharmaceuticals, food processing, and power generation.
Key characteristics of polyester filter bags include:
Material: 100% polyester fibers with options for various surface treatments (e.g., singed, glazed, anti-static, water & oil repellent).
Temperature Resistance: Can typically withstand continuous operating temperatures up to 150°C (302°F).
Chemical Resistance: Good resistance to most organic acids, solvents, and oxidizing agents; however, limited resistance to strong alkalis and high-temperature hydrolysis.
Filtration Performance: Offers high tensile strength, good dimensional stability, and efficient particle capture, with filtration precision that can be tailored to specific needs.
Applications: Used in baghouse dust collectors and in industries requiring reliable particulate removal from process air.
Thanks to its balance of performance and affordability, the polyester filter bag remains one of the most versatile and dependable choices for filtration in a wide range of industrial settings.
