Needled felt filter-bag is one kind of economical disposable filter material. It is made with the needle-punching method, no fiber migration in the surface, three dimensional structure and the use of hot melt seamless joining technology ensure effective filtration and no-leakage.
     It is applicable to liquid materials with low and medium viscosity, which has a stable flow rate to effectively intercept kinds of softness and hardness impurities.
     Depending on different filter fineness and filter area , there are four kinds of materials such as PO,PE,NT,PTFE and four kinds of filter-bag can be chose.

      Characteristics
