In various industrial fields which are becoming more precise and complicating recently, the materials and enviroment are requested,first of all,to be cleaner and purer than those used in the other industrial fields. This time Daiwabo has developed"SEKISO"for such needs based on its unique manufacturing technology, which is an epoch-making multicomponent cartridge filter made of "DAIWABO NBF"and exhibits excellent filtration perfomance in various fields. Nonwoven fabric layers of "Daiwabo NBF" this part catches coarser particles and acts as a pre-filter for inside molded layers. Thermally molded nonwoven fabric layers of "Daiwabo NBF"(Molded layers) This part is composed of molded layers of higher density in which fibers are three-dimentionally donded and can catch finer particles which are not filtered off through non woven fabric layers. What is "Daiwabo NBF?"
