Knitted mesh
Flexible by design.
Knitted wire structures for droplet separation, EMI shielding, sealing and support — plus 3D knitted spacer fabric where airflow and comfort meet.
Knitted mesh behaves unlike any woven cloth: interlocked loops create a springy, three-dimensional structure that can compress, conform and recover. That makes it a depth medium rather than a surface screen — ideal wherever droplets, vibrations or irregular surfaces are the problem.
As demister (mist eliminator) pads, knitted mesh removes entrained droplets from gas streams in columns and separators. As gasketing and EMI shielding, it seals doors, panels and enclosures electrically and mechanically. As a support and protection layer it cushions membranes and delicate media.
The same knitting technique in polyester yarn produces 3D spacer fabric: two textile faces held apart by pile yarns, 3 to 30 mm thick. It distributes pressure peaks and moves air and moisture — micro-airconditioning for filters, seating and industrial supports. Washable, recyclable and non-toxic.
Applications
- Mist eliminators and coalescer internals in process columns
- EMI shielding gaskets for enclosures and cable entries
- Sealing and packing under vibration
- Support and spacing layers in filter assemblies
- Spacer fabric: air filters, seating, mattresses, technical cushions
Features & benefits
- Compressible and resilient — follows irregular surfaces
- Co-knit options (wire + PTFE or glass yarn) for wet or abrasive duty
- Pads engineered to vessel: density, thickness, grid and segmentation
- Conductive alloys for reliable EMI performance
- Spacer programme: 25+ standard 3D types from stock

Stainless 304/316L is standard for process duty; copper, aluminium and Monel™ serve shielding and marine atmospheres; Hastelloy™ handles aggressive chemistry. Spacer fabric is knitted in polyester (PES), with hydrophobic executions available.
Frequently asked questions
What determines demister pad performance?
Density, pad thickness, wire diameter and gas velocity. We size pads to your vessel and duty (droplet size, allowable ΔP) and deliver them with support grids, segmented to pass through the manway.
Is knitted mesh a filter?
It is a depth separator rather than a precise sieve: excellent for droplets and coarse particles, wrong for exact micron ratings. For those, combine it with woven or sintered media — something we do daily.
