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

- 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

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.
Which pad density do I choose: 80 or 300 kg/m³?
Higher density catches finer droplets but costs more pressure drop and fouls sooner. Clean gas and fine mist push you towards the dense end; dirty or fouling service towards open, thicker pads, sometimes in two layers. Give us gas, velocity and droplet size and we size it to the vessel.
When is co-knit mesh (wire plus PTFE or glass yarn) worth it?
In wet or abrasive duty: the yarn raises capture efficiency on small droplets and protects the wire, at some extra ΔP. Typical in final polishing stages and aggressive scrubber service. For dry, clean gas, plain wire stays the simpler and cheaper pad.
Which material for EMI gaskets in coastal or marine service?
Monel™ is the default where salt atmosphere meets shielding: conductive and highly corrosion-resistant. Copper shields best but suffers outdoors; stainless trades a little conductivity for durability. We knit all three: the enclosure environment decides.
