Knitted Demister Mesh

Knitted wire mesh demisters, also known as demister pads or mist eliminators, are essential filtration components used in gas-liquid separation processes. Their main function is to capture and remove liquid droplets from gas streams, thus improving product purity and protecting downstream equipment. They are widely used in industries such as chemical processing, petrochemicals, environmental engineering, metallurgy, and pharmaceuticals.


Knitted wire mesh demisters are made by knitting fine metal  into a mesh structure using specialized knitting machines. The knitted mesh is then layered and compressed to the required thickness and density. Key structural features include:

Multi-layered interlocking structure: Enhances droplet capture efficiency.

Large specific surface area: Increases contact between droplets and mesh.

Lightweight and flexible: Easy to handle and install.

High porosity (typically over 98%): Low pressure drop and high gas throughput.


Knitted wire mesh is made by knitting machine similar to jumpers and scarves machine. The final knitted mesh is in the structure of inter-connecting loops, and it is similar to a long knit sock. We can produce multi- filament, co-knit and multi-strand knitted wire meshes. Our knit wire diameter is commonly range from 0.11 mm to 0.35 mm. But for special applications, knit wire as small as 0.03 mm or as large as 0.8 mm in diameter is available.
