Knitted Wire Mesh - Knitted Wire Mesh Filter


Knitted wire mesh filter is a kind compressed knitted wire mesh filter elements providing a random flow and filtration effects. The interlocking wire loop structure of knitted wire mesh provides many advantages over other materials for air and liquid filtration.

When layered, spiral wound or compressed, knitting mesh has a tortuous path for highly effective particle capture. By careful selection of wire type, diameter, density and shape, it is possible to overcome challenging filtration problems that other materials find difficult to handle.

Knitted mesh filter has a wide variety of forms

Knitted mesh filters can be supplied in any metallic or non-metallic material that can be drawn into a filament. Knitted wire filter materials can be stainless steel wire, copper wire, galvanized iron wire and polyamide fiber. They are available in a wide variety of forms including mesh rolls, circular and rectangular pads, complete filters and compressed elements. Metal alloys or plastics can be provided. These knitted meshes are highly resistant to corrosion and can withstand temperatures in excess of 1000°C.

The flexibility of knitted mesh enables the mesh to withstand thermal shock and vibration without breaking up. This provides considerable advantages over paper and sintered filters and also permits a tight interference fit within housings without machining to close tolerances. Low-cost tooling enables the production of compressed elements that give a minimal pressure drop and also excellent recovery characteristics after compression.
