Filtration & Separation

From biomedical researchers to mechanical engineers, from product designers to coffee manufacturers, all types of customers rely on wire mesh for specific filtration and separation purposes. Wire mesh is an extremely versatile industrial product that affords countless clear opening sizes. For industrial users, determining the appropriate opening size is important; in most cases, for example, it is critical to know the size of the particle you are looking to separate or the liquid viscosity or flow rates required for filtration or straining.

Often, industrial users of wire mesh will specify the type of material, mesh count and diameter wire they need for their specific application. Depending upon a customer’s requirement, these meshes can be sold in sheet, piece or roll form. Because there are thousands upon thousands of filtration and separation applications that can use wire mesh, Darby is unable to provide specific recommendations for a specific applications.

As a reference, however, one of our long-time customers recently provided us with this valuable information which may prove useful in attempting to identify appropriate mesh sizes.

Common Particle Size and Corresponding Mesh Size:
Corn Kernels:
4 x 4 Mesh
8 x 8 Mesh
Ground Coffee:
20 x 20 Mesh
Table Salt:
40 x 40 Mesh
80 x 80 Mesh

It is also critical to determine what alloy or material will best meet your requirements. The six material options listed below represent the most popularly requested; other options are available. Please contact us with your specific requirement or with any questions you may have.
