Overview

General Description

P84 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 working temperature of P84 Needle Felt Air Filter Media can reach 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
