Two tools, honest by design.
A pre-selector that names a candidate series and its limits — never a fake model promise — and a mesh↔micron converter that runs off the US sieve series, labelling exact, approximate and nearest-reference values separately. No email walls.
Machine pre-selector
Three questions. The result is a candidate series with its limits — sizing a specific model takes particle size, density, moisture and capacity data, ideally from a sample test.

What are you screening?
Mesh ↔ micron converter
Type either one — you get the other, the closest standard aperture, and whether the cut usually needs ultrasonic help. Both directions read the same reference table.
Exact match — US sieve series
Exact match in the US sieve series — typical duty: metal powder guard.
