Mesh Sizes and Microns
What does mesh size mean?
Figuring out
mesh sizes is simple. All you do is
count
the number of openings in one inch of screen (in the United States,
anyway.)
The number of openings is the
mesh size. So a 4-mesh screen means
there are
four little squares across one linear inch of screen. A 100-mesh screen has 100
openings, and so
on. As the number describing the mesh
size increases, the size
of the particles decreases. Higher numbers equal finer material. Mesh size is not
a precise measurement of particle size.
What do the
minus (-) and plus (+) plus signs mean when describing mesh sizes?
Here’s a simple example of how they work. –200-mesh would mean that all particles
smaller than 200-mesh would pass through. +200 mesh means that all the
particles
200-mesh or larger are retained.
How fine do
screens get? That depends on the wire thickness. If you think about it,
the finer the weave,
the closer the wires get together, eventually leaving no space
between them at
all. For this reason, beyond 325-mesh particle size is usually
described in
“microns.”
What is a micron? A micron is another measurement of particle
size.
A micron is one-millionth of a
meter or one twenty-five thousandth of an inch.
Powerwise baskets come in the following standard mesh sizes. 14,30,60 & 100
Our filters are assembled with 60 mesh unless specified. This
mesh has given good results across the board. Remember the finer
the mesh the more you filter. It means you could eb cleaning the filter
more often than required.
