Compressed Knitted Mesh Filters are engineered filtration components manufactured by compressing knitted metal wire mesh into a dense, dimensionally stable porous structure. Through precise control of wire diameter, mesh construction, layering, and compression ratio, these filters achieve predictable pore size distribution, high mechanical integrity, and consistent filtration performance.
Unlike loose or uncompressed knitted mesh, the compression process transforms the flexible mesh into a self-supporting filtration medium capable of withstanding higher pressures, flow velocities, vibration, and thermal stress. The resulting three-dimensional labyrinth structure enables depth filtration, capturing solid particles, liquid droplets, aerosols, and mist throughout the entire filter volume rather than only on the surface.
Compressed knitted mesh filters are widely used in gas and liquid filtration, mist elimination, flow conditioning, vibration damping, and noise attenuation. Depending on material selection, they can operate reliably in corrosive environments, high-temperature applications, and cyclic operating conditions. Their cleanability and reusability further contribute to long service life and reduced operating costs.

Different Shapes and Materials of Compressed Knitted Mesh Filters
Compressed knitted mesh filters are multi-functional filtration components manufactured from high-quality metal wires such as stainless steel, copper, or brass. The wires are first formed into knitted mesh structures using specialized knitting machines and are then compressed into precise shapes and densities through dedicated compression equipment. This manufacturing process ensures excellent mechanical strength, stable structure, and consistent filtration performance.
According to different industry standards and application requirements, compressed knitted mesh filters are available in a wide variety of specifications. They can be customized by material grade, wire diameter, knitting pattern, mesh structure, compression density, shape, and overall dimensions. Common configurations include cylindrical, ring, disc, and custom-designed forms to meet specific installation and performance needs.
We are able to supply a comprehensive range of compressed knitted mesh filters and provide customization services to meet your exact technical and operational requirements.
Different Materials
Compressed knitted mesh filters can be manufactured from a wide range of metal materials to suit different operating environments and performance requirements. Common materials include stainless steel (such as AISI 304, 316, and 316L), which offers excellent corrosion resistance, temperature tolerance, and mechanical strength. Copper and brass are often selected for applications requiring good electrical conductivity, thermal performance, or specific chemical compatibility.
For more demanding conditions, special alloys such as Monel, Inconel, Hastelloy, or nickel-based alloys can be used to provide enhanced resistance to high temperatures, aggressive chemicals, or extreme pressure environments. Material selection is fully customizable based on the medium, operating temperature, pressure, and industry standards.
Different Wire Types
Various wire types can be used in the knitted mesh structure to achieve different filtration and mechanical properties. Round wire is the most common option, providing uniform structure, stable compression behavior, and reliable filtration performance.
Flat wire or shaped wire can also be applied in specific designs to increase contact area, improve particle capture efficiency, or enhance structural rigidity. Additionally, wire diameter can be precisely controlled, allowing fine adjustment of porosity, permeability, and dirt-holding capacity. Single-wire and multi-wire combinations are available to meet specialized filtration or separation requirements.
Different Mesh Types
Flatten type compressed knitted mesh is produced by flattening the knitted wire structure before final compression, resulting in a compact, uniform surface and stable internal structure. It offers higher mechanical strength, consistent density, and controlled porosity, making it suitable for applications requiring stable filtration performance and resistance to deformation under pressure.
Ginning type compressed knitted mesh is formed by opening and loosening the knitted wire loops prior to compression, creating a bulkier structure with greater internal void volume and elasticity. This type provides high permeability, low pressure drop, and excellent dirt-holding capacity, and is commonly used in high-flow filtration, mist elimination, and oil–gas separation applications.
Different Shapes
Compressed knitted mesh filters can be manufactured in a wide variety of shapes to match different installation and system requirements. Standard shapes include cylindrical, ring, disc, and rectangular forms.
For complex or non-standard applications, custom-designed shapes such as stepped cylinders, flanged elements, conical filters, or integrated assemblies can be produced according to customer drawings or samples. Precise control of dimensions and compression density ensures proper fit, sealing performance, and reliable operation in the final application.
Applications of Compressed Knitted Mesh Filters
Specialized manufacturing and controlled compression processes ensure that uniform density and consistent pore structure are maintained throughout the entire compressed knitted mesh filter. During extended production runs, statistical process control (SPC) is applied to monitor and maintain product uniformity, repeatability, and performance stability.
In addition to gas–liquid and solid–liquid filtration, Compressed Knitted Mesh Filters are widely used in the following applications:
- Engine and oil filler cap breathers
Enable pressure equalization while separating oil mist and particulates. - Shock and vibration absorption components
