This standard aims to determine the arrestance of air filter bag with synthetic dust by using a gravimetric method and the efficiency of fine filters by using a particle counter method.The standard has a double classification system that uses letters and numbers: G and F respectively for air filter bag, followed by numbers from 1 to 9 as shown below.
|Classification of coarse and fine filters according to EN 779 and EU 4/5|
|Type of filter||EN 779||Avg. arrestance with||Avg. opacimetric||Final pressure drop||Class Eurovent 4/9*|
|Coarse||G1||Am < 65||250||EU 1|
|G2||65 < Am < 80||250||EU 2|
|G3||80 < Am < 90||250||EU 3|
|G4||90 < Am||250||EU 4|
|Fine||F5||40 < Em < 60||450||EU 5|
|F6||60 < Em < 80||450||EU 6|
|F7||80 < Em < 90||450||EU 7|
|F8||90 < Em < 95||450||EU 8|
|F9||95 < Em||450||EU 9|
Am = Average arrestance referred to the Weight/Gravimetric method
Em = Average efficiency referred to the Colorimetric/Opacimetric method
* According to the EUROVENT 4/5 classification that does not specify the final pressure drop.
First , the air filter bag is located the fan air inlet it mainly filter large dust and impurities in the air.
Second, medium efficiency filter located on the ceiling of the clean room filter effectively , which is the most main filter, fully filtered to air evenly spread, forming the laminar state and up to best atomosphere.
