There are three elements that you need to know to ensure your filter works as intended. Wire diameter, opening size, and mesh count all play a role in the effectiveness of a mesh filer.
Wire Diameter: The width of each wire used to weave the filter
Opening size: The Space between any two wires
Mesh count: The number of openings in an inch in any direction
Mesh count=25.4/(wire diameter+opening size)
If you were to submit a request for a 80×80 mesh filter with a wire diameter of 0.10mm, the mesh supplier would have enough information to identify the mesh count and wire diameter. In turn, the mesh supplier can also calculate the opening size.
To that end, if any two elements are provided, the third can be determined; however, for best results, you should have all three ready before reaching out to the mesh filter supplier.
