Level 2 is for industrial treatment.
The big difference between level 1 and Level 2 is At point 1: PP raw material At point 2: The production process During the whole production process, there is an internal story in this industry.
The difficulty during melt blown production is to accurately control the machine operation temperature in order to realize the graded pore size structure from loose outside tight inside, normally 3-4 pore layer structure.
In general, graded pore structure assures a bigger dirt holding capacity and the longer service lifetime of one piece of melt blown cartridge filter.
You must wonder what will happen if melt is blown without graded pore size structure and with graded pore size structure?
