Micro Mesh Filters

A 100 mesh filter has openings of approximately 149 microns, since mesh count refers to the number of wires per linear inch and inversely correlates with opening size. As mesh count increases, micron rating decreases, meaning finer filtration. Exact micron values can vary slightly depending on wire diameter and weave or knit pattern used in manufacturing.

400 mesh is finer than 200 mesh. Mesh count indicates the number of openings per linear inch, so a higher number means smaller openings and finer filtration. A 200 mesh filter has openings around 74 microns, while a 400 mesh filter has openings around 37 microns, making it suitable for capturing much smaller particles.

Micro mesh filters are commonly available in stainless steel (SS304, SS316), copper, brass, aluminum, and specialty polymers like PEEK for aggressive chemical environments. Material selection depends on the application's temperature range, corrosion exposure, electrical conductivity needs, and required mechanical strength, with stainless steel being the most widely used for general industrial filtration.

Knitted wire mesh is looped like fabric, giving it high flexibility, stretchability up to 300%, and a three-dimensional structure ideal for filtration, demisting, and vibration damping. Woven wire mesh uses interlaced straight wires, producing a flatter, more rigid structure. Knitted mesh generally offers greater surface area and porosity control for filtration purposes.

Yes, micro mesh filters can be custom-engineered for specific wire diameter, mesh density, and porosity, ranging from near-zero to over 98% void volume. Manufacturers adjust knitting parameters and compression to achieve precise filtration ratings, allowing filters to be tailored for exact flow rate, particle retention, and pressure drop requirements across industries.

Selecting the right micro mesh filter depends on the fluid or gas being filtered, required particle retention size, operating temperature, chemical exposure, and pressure drop tolerance. Consider material compatibility (stainless steel, copper, or polymer), mesh density, and whether the application requires vibration damping, mist elimination, or high-purity filtration standards.
