Needle punched felt filter rolls for liquid filtration

Non woven needle punched felt is deep three-dimensional filter material, three-dimensional filter layer is with fluffy three-dimensional depth, with many twists and turns. The filtration layer is formed by needle punching method from 100% pure fiber. Its characteristic is that the fibrous tissue is loose and the high air gap rate increases the volume of the impurity.

This kind of fiber material belongs to the compound intercepting mode, which effectively removes solid and soft particles. That is, larger particle impurities are trapped on the fiber surface, and fine particles are captured in the deep layer of the filter material, which ensures that the process will not be damaged due to increased pressure.

Therefore, filtration has high filtration efficiency.

It has a wide range of applications.

The high temperature sinter and calender treatment of filter material surface can effectively prevent fiber from falling off during filtration.

It is pollution-free, low pressure and high flow rate. At the same time, it also avoids the traditional roller treatment resulting in filter holes blocked very much and shortens the life of filter bags.

The filtering precision range includes: 0.5µm, 1µm, 5µm, 10µm, 25µm, 50µm, 75µm, 100µm, 150µm, 200µm, 250µm, 300µm.
