Polyimide P84 Needle Felt Media
The Polyimide P84 Needle Felt Media is a type of High Temp Needle Felt Air Media with the working temperature up to 260℃. The section is irregular leaf-shaped, it can improve filtration effect greatly. Polyimide Needle Felt Media itself is with good hydrolysis resistance and anti-oxidation characteristics.
Briefly Introduction:
The imported P84 fiber has the features of its fineness and irregular fiber, which leads the fiber surface area to become bigger and to provide a lot of small pores, so that the surface filtration is more efficiency and deeply.
As the dust remains in the surface of the filter mat and hardly penetrated, therefore, it needs low pressure for back washing to reach the significant efficiency and excellent fine powder collection. The Polyimide P84 Needle Felt Media is a type of High Temp Needle Felt Air Media with the working temperature up to 260℃. The section is irregular leaf-shaped, it can improve filtration effect greatly. Polyimide Needle Felt Media itself is with good hydrolysis resistance and anti-oxidation characteristics.
Features:
Non-flammable and thermos table organic fiber
Offers extended bag life in low pH applications
Helps reduce differential pressure across the bag house
Operates in high temperature applications against acid attacks and is resistant to flex abrasion (unlike Fiberglass).
Not recommend for high concentration of alkalies at high temperatures.
Continuous operating temperature 240°C
Applications:
Power Generation
Cement, Mining & Rock Products
Asphalt & Aggregate
Mining & Minerals
Waste Incineration
Chemicals & Pharmaceuticals
Food & Beverages
