Sintered metal filter

Filter type

Filtration and Filter

“Filtration” is the operation of separating solid stuff from a liquid or gas by passing a mixture of a solid in a liquid or gas through a filter medium with many fine holes.
The tool that performs this operation is the “filter”.

Filter classification

There are two types of filters, a depth filter and a screen filter.
The depth filter captures the object internally, and the screen filter captures the object on the surface.
Screen filters also include membrane filters, ultrafiltration filters, dialysis membranes and reverse osmosis membranes.

Filtration classification

Depending on the filter used, there are “coarse filtration”, “microfiltration”, “ultrafiltration” and “reverse osmosis”.

Filtration Size Filter classification Filter use Captured stuff (e.g.)
coarse filtration > 10μm a depth filter Pretreatment to prevent filter clogging Algae, Fungi, Pollen etc.
microfiltration 50nm – 10μm a membrane filter Sterilization operation Bacteria (E. coli), etc.
ultrafiltration 1nm – 50nm an ultrafiltration filter Fractionation and concentration with a molecular weight of 1,000 kDa or less Hemoglobin,Virus, etc.
reverse osmosis < 1 nm dialysis membranes and reverse osmosis membranes Water purification, etc. Glucose, etc.

Experiences of manufacturing sintered filters

Sintered filter

Sintered metal (= porous metal) is the product manufactured by the powder metallurgy method (, which is the manufacturing method in which metal powder is molded and sintered to make a metal product). A product in which the sintered metal is made porous and all the pores are connected is a sintered metal filter.
The names “sintered metal”, “sintered filter”, “sintered metal filter”, “sintered metal element”, “sintered element”, and “porous metal” are all the same product.

Features of sintered filter

It has the following characteristics.
