Clean workshop primary filter use grade Everything you want to know is here?

Clean workshop filter grade is divided into G1 level, G2 level, G3 level, G4 level four grades, mainly used in the primary filtration section of clean room, mainly used to filter dust particles above 5μm, is used in optical electronics, medical pharmaceutical, food and beverage, biological laboratory, touch screen, instrument and other industries, generally with other air purification equipment used. For example, FFU, air shower, clean shed, etc., the specific advantages and characteristics of use are explained to you in detail:

Stainless steel, paper frame, aluminum frame, galvanized frame, etc., filter materials are non-woven fabric, nylon mesh, activated carbon filter material, metal hole mesh, etc., the protective net has double-sided spray plastic wire mesh and double-sided galvanized wire mesh.

Air filter (also known as air filter or air filter), according to the performance standards of air filter, can be divided into initial effect filter (also known as coarse effect filter or pre-filter), medium effect filter, high efficiency HEPA filter, ultra-high efficiency filter (H13 or more).

Air pollution is serious, the domestic air filter industry has also begun to grow vigorously, due to the early development of foreign air filtration industry, most of the domestic reference air filter in the United States and European standards, combined with the national conditions of our country, established a new national standard GB/t14295-93 and gb13554-92 now in our country, referring to the European standard more, The categories are roughly as follows:

The grade of the primary effect filter in the clean workshop is divided into 4 categories according to the European standard, in order to remove particles above 5 microns, the efficiency is between 15-80% : the coarse effect filter is divided into four levels (G1 ~ G4) :

The effective rate of G1 particle size is ≥5.0μm, and the filtration effective rate is 20, corresponding to the US standard C1.

G2 particle size efficiency ≥5.0μm, filtration efficiency of 20~50, corresponding to the US standard C2 ~ C4;

G3 particle size efficiency ≥5.0μm, filtration efficiency between 50 and 70, corresponding to the US standard L5;

G4 particle size efficiency ≥5.0μm, filtration efficiency between 70 and 80, corresponding to the US standard L6-L7;

Air filters are recognized by more and more people, it improves air quality and ensures people's health, and has been widely used, such as medicine, food and other industries are inseparable from all kinds of efficiency filters.
