Effect of filter material thickness on filter cotton efficiency of air filter

Time: 2023-02-23

Shanghai SFFILTECH Co., LTD. The influence of air filter material thickness on the efficiency of filter cotton

Some customers believe that the thicker the thickness of the filter cotton, the higher the efficiency of the representative, this is fallacy, is not valid. Because there are many factors determining the efficiency of air filter cotton, the thickness only occupies one corner, so we can not the following absolute conclusion. The following by Shanghai SFFILTECH to explain the impact of air filter material thickness on its efficiency:

Factors affecting the efficiency of filter cotton:

1. Density

2. Thickness

3, the thickness of the fiber

4. The practice of filter cotton

5, the structure of the filter cotton

The efficiency of filter cotton is divided from low to high: G1, G2, G3, G4, F5, F6, F7, F8, F9, at present, the efficiency that can be achieved by the filter cotton is G1-F9, and the initial and intermediate effect, but there is no efficiency. The efficiency in the market is widely said by the merchants. If the thickness or density is increased on the basis of the original, it is said to be efficient, which has not been proved by experiments.

The conventional thickness of filter cotton is divided into: 3mm, 5mm, 8mm, 10mm, 15mm, 20mm, 22mm, 25mm, 30mm and so on, as an air filtration industry, the maximum thickness of the filter cotton reference value is 30mm, once the thickness of the filter cotton exceeds 30mm, the resistance will exceed the force borne by the fan, thus improper use, of course, This is to exclude fluffy filter cotton, such as paint mist filter cotton, we refer to synthetic fiber materials here.

The efficiency corresponding to the thickness of common filter cotton:

Synthetic fiber 3-5mm: G1

Synthetic fiber 5-8mm: G2-G4

Synthetic fiber 10-20mm: G2-G4

Synthetic fiber 22-25mm: F5

Fine fiber 30mm: F6

Fine fiber 5-8mm: F5-F
