What does Mesh mean in a Strainer?
The mesh or micron size will tell you what size particles will be stopped, or strained, from the liquid flowing through the strainer.
Strainers are made from perforated screens or mesh screens. Perforated screens are made by punching a number of holes in a flat plate and are used for filtering relatively coarse material. Mesh screens are made by forming fine wire into a grid. Perforated screens are usually used to support mesh screens.
