Filter Media

Knitwire Trading (PTY) Ltd supplies a variety of knitted wire mesh filter media designed for demanding industrial filtration and separation tasks. Our filter media can be configured to meet specific performance requirements using different wire gauges, knit structures, layers, and materials, making it suitable for a wide range of process, gas, and liquid filtration systems.

Knitted wire mesh media offers excellent performance where conventional filter media may struggle, providing flexibility, high removal efficiency, and durability in challenging environments. The interlocking loop structure creates tortuous flow paths that effectively capture droplets, particles, and contaminants in both air and liquid streams.

Filter media can be engineered to suit your requirements by varying:

• Wire diameter and material
• Knit type (single knit, multi-knit)
• Layering and compression
• Filter thickness and density

These design options allow Knitwire Trading (PTY) Ltd to tailor mesh characteristics to achieve the desired balance of filtration efficiency, flow capacity, and pressure drop for your application.

Knitted mesh filter media can be supplied in rolls, pads, or compressed elements depending on how the media will be integrated into housings, cartridges, or existing filtration systems.

When used in demisting or coalescing applications, knitted wire filter media can achieve very high removal efficiencies with low resistance to flow, thanks to the inherent open structure and surface area of the knitted mesh.

Available materials include:

• Stainless steel: Robust, anticorrosive, heat resistant, and easy to clean
• Galvanised steel: Economical option for less aggressive environments
• Plastic and polymer materials: Suitable for corrosion-sensitive or chemical applications
• Exotic alloys: For high-temperature or highly corrosive conditions

The flexibility of knitted mesh also helps it withstand mechanical vibration without damage, making it suitable for filtration near rotating equipment or vibration-prone installations.

Knitwire Trading (PTY) Ltd filter media is used across industries including:

• Mist eliminators and liquid coalescers
• Air and gas filtration systems
• Process filtration in petrochemical and oil & gas environments
• Liquid filtration and particle removal
