Dust Collector Filter Bag

PPS filter bags, constructed from polyphenylene sulfide (PPS), offer exceptional filtration capabilities and durability. Key features include:

1. High Temperature Resistance: Operating temperatures up to 160°C (320°F), with surge tolerance up to 190°C (375°F), ideal for applications in incinerators, power generation, cement production, and metal processing.
2. Excellent Chemical Resistance: Resistant to acids, alkalis, and solvents, making them suitable for chemical processing and pharmaceutical industries.
3. Moisture Resistance: Withstands moisture and hydrolysis, making them suitable for applications in food processing and wastewater treatment.
4. High Mechanical Strength: Boasting high tensile strength and tear resistance, ensuring durability and reliability even in demanding environments like mining and construction.
