Knitted mesh
Compressible wire loops.
Knitted wire structures for droplet separation, EMI shielding, gasketing and support. The range also includes 3D spacer fabric for airflow and cushioning.
Knitted mesh consists of interlocking wire loops. The three-dimensional structure can compress, conform to a surface and recover. It is used for depth separation, vibration damping and contact with irregular surfaces.
Demister pads made from knitted mesh separate entrained droplets from gas streams in columns and separators. Knitted gasketing provides electrical contact for EMI shielding at doors, panels and enclosures. As a support layer, the mesh protects membranes and delicate filter media.
Polyester yarn can be knitted into 3D spacer fabric. Two textile faces are held apart by pile yarns, with a thickness of 3 to 30 mm. The structure distributes pressure and allows air and moisture to pass through, for applications including filters, seating and industrial supports. The fabric is washable; recycling and material safety depend on the selected grade.

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?
Knitted mesh is used for depth separation of droplets and coarse particles. It does not provide a defined micron rating as a precision screen would. For fine particle filtration, it can be combined with woven or sintered media.
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. All three are available: the enclosure environment decides.
