Conversion between the mesh number of the metal filter and the filtration accuracy
As we all know, there are always two ways to express the filtration accuracy of metal filters in the filtration industry. One general standard is “micron”, and the other is a more traditional expression – that is, the number of meshes, then what is the mesh number? How should the number of meshes and micrometers be converted? The following is a professional production of stainless steel sintered mesh for 20 years, Xinxiang City Lier Filtration Technology Co., Ltd. to introduce to you:
The term "mesh" refers to the number of wire holes per inch (ie 25.4 mm). Mesh = 25.4 / [wire diameter (stainless steel wire size in stainless steel mesh) + aperture (stainless steel mesh size)].
The filtration accuracy and mesh count in the filtration industry are as follows:
| mesh | μm | mesh | μm |
| 2 | 8000 | 100 | 150 |
| 3 | 6700 | 115 | 125 |
| 4 | 4750 | 120 | 120 |
| 5 | 4000 | 125 | 115 |
| 6 | 3350 | 130 | 113 |
| 7 | 2800 | 140 | 109 |
| 8 | 2360 | 150 | 106 |
