Description

P*4 needle felt has  not only  excellent  property of temperature resistance,which use in  long-term  temperature of **0 °C in the environment, but also has good acid and alkali resistance and low backwash pressure and high-elastic mud cake removal efficiency. P*4 features due to the fineness of the fiber itself significantly and more due to the irregular surface area of fiber cross section which increased the fiber to provide the largest number of tiny pores to filter better than the depth of the surface filter, dust filter needle felt only stay in the surface but failed to penetrate the filter felt, and therefore the pressure against the small and the filter cake washed off bombs to significantly improve the efficiency with excellent micro-powder collection efficiency and the operating pressure difference.
