Mesh Sizes vs. Particle Diameters
Strainers and filters - mesh size vs. particle diameter opening size.
A strainer with a cleanable screen can in general retain particles larger than 45 μm (325 mesh). Smaller particles must be retained in a filter. Mesh size vs. particle diameters for strainers and filters are indicated below.
- 1 μm = 10-6 m = 1 micron
