The overall effectiveness of polyester mesh is determined by the size of the screen openings in the mesh. Larger openings are suited for situations where you are filtering out larger particles. Any particles that are smaller than the size of the mesh opening will not be initially filtered. However, you can use a second filter mesh with smaller mesh openings, to filter out any remaining particles not removed when they were filtered through the larger screen.
Custom Cut Polyester Mesh for Manufacturing has its Benefits
Polyester mesh can be custom cut to fit with your product designs and drawing specifications. Rather than perform the cuts yourself in-house, you can order the mesh already cut to size. Ordering mesh in this manner may cost slightly more. But you gain the benefits of always having mesh available for your production runs and not having to worry about running out.
