P84 needle felts P84 needle felts

  • Product Description
  • Technical Data Sheet

P84 features of its fineness and irregular fiber,which lead the fiber surface area to become bigger and to provide a lot of small pores,so that the surface filtration is more effeciency and deeply.As the dust remain in the surface of the filter mat and hardly penetrated.Therefore,it  need low pressure for back washing to reach the significant efficiency and excellent fine powder collection.
