Understanding Wire Mesh Filters: Technical Parameters and Specifications

A wire mesh filter is essentially a device that uses a woven or expanded metal fabric to separate solid particles from a fluid (liquid or gas). The effectiveness of a filter is determined by several key technical parameters:

Material Composition: Common materials include 304, 316, 316L stainless steel expanded sheet, brass, copper, nickel alloys, and galvanized steel. The choice of material depends on the operating temperature, pressure, chemical compatibility, and corrosive environment. For instance, 316L stainless steel is often preferred in highly corrosive or hygienic environments due to its enhanced resistance to pitting and crevice corrosion.
Mesh Count (LPI): This refers to the number of openings per linear inch. A higher mesh count indicates smaller openings and finer filtration.
Micron Rating: This specifies the smallest particle size (in micrometers) that the filter can effectively capture. Absolute micron ratings mean all particles larger than the specified size are captured, while nominal ratings indicate a percentage of particles captured.
Wire Diameter: The thickness of the individual wires forming the mesh. This affects the strength, flow rate, and open area of the filter.
Weave Pattern: Plain weave, twilled weave, Dutch weave, and reverse Dutch weave are common. Each offers different characteristics regarding strength, open area, and filtration efficiency. Dutch weaves, for example, provide excellent filtration efficiency at very fine micron ratings due to their tightly packed wires.
Filter Shape and Dimensions: Wire mesh filter elements come in various forms, including discs (the focus of our Wire Mesh Filter Disc product), cylinders, cones, baskets, and custom shapes. Dimensions (diameter, height, thickness) are critical for fitting into existing systems.
Operating Conditions: Filters must be specified considering the maximum operating temperature, pressure differential, and flow rate.
