The melt blown filter element is a tubular filter element made of non-toxic and odorless polypropylene particles, which are heated and melted, spinned, drawn, and formed. The entire filter element achieves the real effect of capturing particulate matter according to the density classification, so that the effectiveness of the filter element can be fully utilized; higher dirt retention capacity means long service life, low replacement frequency and cost savings; the surface density of the filter element is lower. Low, and the density gradually increases from the surface to the center of the filter element; there are no surface blind spots that will reduce the flow rate of the filter element and increase the frequency of replacement. If the raw material is mainly polypropylene. It can be called PP melt blown filter element. It is not only used in large quantities in water purification. It also has outstanding chemical compatibility and is suitable for the filtration of strong acids, strong bases and organic solvents. Strong dirt holding capacity, long service life and low cost.

Advantages of melt blown filter element:

　　 1. The pressure loss is small and the filtration efficiency is stable.

PP melt blown filter element has a fine fiber layer inside and a loose fiber layer outside to form a

double-layer fiber structure, which effectively reduces pressure loss and maintains a stable filtration efficiency.

　　 2. High filtration efficiency.

Because the new meltblown filter element is different from the traditional fabric filter material, the fiber

diameter is relatively small, generally 5-25 microns, the irregular porous network structure in three-dimensional

space, the pore size is small, the average pore size is less than 40 microns, the porosity is large, and the average

The porosity is ≥75%, which effectively controls the filtration accuracy, and all the indexes of the PP meltblown

filter element series products produced by our company have passed the inspection of the national authority.

　　3. Long service life, low filtration cost.

PP meltblown filter element has a gradient distribution of pores along the diameter direction. During the filtration

process, the large pore part can accommodate large particles with enough space to ensure that the filter element

will not be blocked quickly, while providing good shape rigidity; the small pore part can be It blocks fine particles

and ensures filtration accuracy, thereby avoiding the disadvantages of fast clogging and short life of the

high-precision filter element, and also reducing the filtering resistance, reducing energy consumption and

improving the service life of the filter element. It is resistant to mildew, acid and alkali, organic or inorganic

solvents.
