Wire Mesh Filters: How They’re Made and How They’re Used

Similar to wire mesh, wire mesh filters are easy to manufacture, are available in different styles and gauges (thickness), and have many uses in many different industries, as well as for consumer and commercial purposes. Typically, the purpose of a wire mesh filter is to separate air or liquids from solid particles, similar to how a strainer functions. The big difference is that wire mesh filters are not only designed to filter out particles; they are also designed to be resistant to warping or other damage from heat, corrosion, and acid. Since wire mesh filters must be so strong and durable, they are typically made out of several different types of alloys like stainless or galvanized steel, aluminum, brass, or copper. These filters may be used alone or in conjunction with other types of filtration devices.

Common gauges or custom made?

When creating wire mesh filters, manufacturers use specifications for commonly used sizes and types of filters to determine the diameter of the wire used, though many manufacturers can also produce custom sizes when needed. A wire’s thickness is measured in millimeters, and the resulting wire mesh filters are measured by their gauge, where the higher the number, the finer the wire. When referencing the mesh size of wire mesh filters, manufacturers are referring to the number of or size of the holes between the wire weaves. Wire mesh sizes are usually measured in microns, millimeters, or inches. Finer and smaller wire mesh filters may have holes as small as 0.25 inches or as large as 1 inch. The smaller the holes between the wire weaving, the better the filter will be at catching even tiny particles that might otherwise slip through larger holes.

Common Uses

Wire mesh filters are commonly used in air conditioning, heating, and other air filtration systems. In these systems, the filters keep dust, dander, pollen, and other solid debris from mixing with the air that is then pumped into buildings. Likewise, in water filtration systems, wire mesh filters keep solid debris from flowing into the water that is pumped into aquariums, tanks, pipes, and wells.

You can also find wire mesh filters in use in the food and drink industry, most notably in wine and beer factories. The petroleum industry also makes use of wire mesh filters in order to remove impurities from the oils and gases they produce.

Where to purchase?

Because wire mesh filters can be mass produced by machines in a fast and efficient manner, and because they are so commonly used in many types of filtration systems, they are both affordable and easy to find. Standard hardware stores, and speciality tube stores like Beverlin, typically stock wire mesh filters in varying sizes and shapes, including flat sheets that can then be cut for custom configurations. You can also purchase wire mesh filters online, often directly from manufacturers.
