What does "mesh" mean? – An explanation for our customers
In the world of surface technology and filtration, many people come across the term "mesh". But what exactly does this term mean and how does it influence the selection of the right filter or sieve? In this article, we aim to provide clarity and help you make the right choice for your specific requirements.
What is mesh?
"Mesh" is a unit of measurement that describes the number of openings (or meshes) per inch in a screen or filter. The higher the mesh number, the finer the screen, because there are more openings per inch. So a 10 mesh screen has 10 openings per inch, while a 100 mesh screen has 100 openings per inch.
Why is mesh important?
The mesh number is critical to ensuring that the sieve or filter retains or passes the correct particle sizes. This is especially important in applications where purity or specific particle size is of great importance.
Converting mesh to microns
It is often necessary to convert mesh count into microns (µm) to get a better understanding of the particle size that a screen or filter will allow to pass. Here is a rough conversion chart to help you along the way:
| Mesh number | Aperture size (micrometres) |
|---|---|
| 10 Mesh | 2000 µm |
| 20 mesh | 841 µm |
| 40 mesh | 400 µm |
| 60 mesh | 250 µm |
| 100 mesh | 149 µm |
| 200 mesh | 74 µm |
| 400 mesh | 37 µm |
These conversions are approximate and may vary slightly depending on the wire diameter and the material of the sieve.
Practical example: Choosing the right filter
Imagine you need to filter a liquid and want to remove particles with a size of 100 µm. Based on the table above, you would choose a filter with a rating of about 150 mesh, since this filter retains particles close to the desired size.
Conclusion
Understanding mesh count and its significance is crucial to selecting the right filter or screen for your surface treatment needs. We hope this article helps you better understand mesh count and make the right choice for your specific needs.
