Filtration - Mesh Filters

Home » Applications & Products » Engineering Applications » Filtration - Mesh Filters


The unique, interlocking wire loop structure of KnitMesh Technologies knitted wire mesh provides many advantages over other materials for air and liquid filtration.

Our knitting process creates a material that, when layered, spiral wound or compressed, produces a tortuous path for highly effective particle capture. In fact, 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 Comes In A Wide Variety Of Forms

KnitMesh Technologies knitted mesh filters can be supplied in any metallic or non-metallic material that can be drawn into a filament. They are available in a wide variety of forms including mesh rolls, circular and rectangular pads, complete filters and compressed elements. Where necessary, metal alloys or plastics can be provided that are highly resistant to corrosion and can withstand temperatures in excess of 1000°C.

Thermal & Shock Resistance In Wire Mesh Filters

The flexibility of knitted mesh enables the material 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.
