Security filter using high quality imported 306L stainless steel or 304 stainless steel material of the body, the health food grade filter, used to filter the multi medium filtered fine material (such as tiny quartz sand, activated carbon particles, etc.), to ensure the water quality of the filtering precision and protective membrane filter element is not affected by the large particulate material damage.

One, working principle
Precision filter is employed to shaping filter material, under the action of the pressure, the liquid through the filter, the filter residue can remain on the pipe wall, the filtrate through the filter outflow, so as to achieve the purpose of filtering.

Shaping filter: filter, filter, filter, filter, sintering, Wirewound filter meltblown filter etc.. Because of the different filters, filter pore size is not the same. Precision filter is a filter ( filter ) and ultrafiltration between a filter, filtering the aperture is generally in the range of 0.5 ~ 120 ~ m range. The same type of filter material, according to the shape and size can be divided into different specifications.

Wirewound filter ( also known as honeycomb filter) has two kinds: one kind is polypropylene fiber, polypropylene frame filter, maximum use temperature of 60 DEG C; the other is a cotton fiber - stainless steel frame, the maximum use temperature of 120 DEG C.

Meltblown filter is made of polypropylene in melt blowing process, the formation of filter, the maximum operating temperature of 60 DEG C. Precision filter can remove suspended matter, some colloidal substances and fine particles.
