disagree  Katalin Horváth McClure: The "screen" at the end is one thing that is being measured by two different units. In other words, it is a 40 mesh screen AND also a 420 micron screen. To separate the "screen" to go ONLY with the "micron" part is a mistake. No such word exists.

ミクロン　スクリーン

Explanation:
40 Mesh/420 Micron Screen
40メッシュ/420ミクロン　スクリーン
40 Mesh/420 Micronはサイズのことです。
メッシュとミクロンは二つの単位です。
40メッシュはおよそ４２０ミクロンであるという意味です。
つまり、スクリーンのサイズを二つの単位で表記しています。

Maynard, I think the difference between the 400 and 420 microns is that one of the numbers (420) is a so-called ¥"absolute¥" particle retention size, the other (400) is the ¥"nominal¥". The asker¥'s text is a line from a spec (I assume) where they would probably list the absolute size, and the table in my reference is probably only about nominal sizes.

agree  cipher: 品目であれば「ミクロン」で全く問題ないと思います．SPECであれば従来用いられてきた「ミクロン」に代わってSI単位系を用いて「マイクロメータ(μm)」と表記することが多くなってきました．

neutral  Maynard Hogg: The first reference says that 40 mesh is 0.400 mm, not 0.420. No such problem with the second reference, however.

-> Could be typo on either side (asker or reference). My point was only to show that these are two different units of measurement.
