140 mesh to micron: 106 µm (0.106 mm)
140 mesh is an opening of 106 microns, which is 0.106 mm or 0.00417 inch, on the ASTM E11 US standard sieve series. The nearest wedge wire equivalent is a 106 micron (0.106 mm) slot, because wedge wire is specified by its slot rather than a mesh count.

Equivalent wedge wire slot: 106 micron (0.106 mm)
Wedge wire is specified by its slot directly, so a wedge wire screen has no mesh count. Quote the slot in mm or microns.
Your inputs and results go into the quote form, so an engineer can check them against your operating conditions.

What passes through 140 mesh
As a general reference on the Wentworth grade scale, particles smaller than 106 µm pass: silt, clay. Real separation also depends on particle shape, the screen's open area and how the screen is loaded.
The wedge wire equivalent
A wedge wire screen is specified by its slot, so the equivalent is a 106 micron (0.106 mm) slot. Because the V-shaped wire widens behind the slot, particles that pass the face do not wedge in it. See mesh to micron and slot size and how to choose slot and open area.
