過濾器過濾面積通常指絲網(wǎng)的有效流通面積，可以查閱下表“濾網(wǎng)規(guī)格”得知有效面積，濾網(wǎng)總面積與有效面積率的乘積即為過濾面積（有效流通面積）。通常，考慮過濾面積按過濾器公稱通徑的20倍設(shè)計(jì)，已足夠滿足使用場(chǎng)合。除非在非常見的特殊環(huán)境使用，才予以特殊考慮。

The filtration area usually refers to silk screen's effective flow area, May the consult next table “the mesh specification” knowing effective area, Mesh total area and active surface rate product namely for filtration area (effective flow area). Usually, The consideration filtration area according to the filter nominal size's 20 time of designs, enough has satisfied use situation. Only if in non- the common special environment use, only then gives the special consideration.

過濾器過濾網(wǎng)孔目數(shù)（目數(shù)/英寸）的選擇，主要考慮需攔截的雜質(zhì)粒徑，依據(jù)介質(zhì)流程工藝要求而定。各種規(guī)格絲網(wǎng)可攔截的粒徑尺寸查下表“濾網(wǎng)規(guī)格”。

Hole Mesh (mesh / inch) of choice, consider the need to intercept the main impurities in diameter, according to media flow Process requirements. Various specifications of wire to intercept the particle size can search under the table "filter specifications."
