ISW Corporation is a custom manufacturer of a wide range of mist eliminator units used for separating and collecting water or oil droplets from process gases and mist from smoke elimination systems.    Mist eliminator systems are used in many applications:

  • Petroleum refining
  • Oil & gas
  • Chemical
  • Water treating industries
  • Industrial kitchens

Oil or water mist in exhaust streams is typically a potential health and environmental hazard.    When the mist or exhaust gas passes through the knitted wire mesh, the mist moves freely through the mesh.  However, as the liquid droplets come in contact with the knitted mesh they adhere onto the surface of the wires and build into larger droplets that drop out due to gravitational forces.  This process of removing toxic gases, oil mist or sulphuric acid gas has a removal efficiency up to 99%.  Knitted wire mesh pads have no moving parts, can be made of high grade stainless steel and require little maintenance, therefore they are the most economical solution for mist elimination.



Width: 15 to 50 mm

Thickness:  2.0mm to 6mm

Rod Diameter:  4.0mm to 10mm

Material:  Same as Knitted Wire Mesh Type

Grease Filters

Knitted wire mesh elements are commonly used in industrial cooking extractors to eliminate entrained grease and fat from being drawn into the extraction ducts, reducing the risk of fire hazards and also providing essential protection to expensive motors and blowers.
Knitted wire mesh filters provides a collection system offering a low resistance with maximum efficiency up to 98%. A knitted mesh pad is designed with a specific thickness, density and wire size to optimize separation efficiency and flow capacity for expected process conditions. Knitted mesh pads can often be replaced re-using the support channel frame and grid over again.
Construction is typically from multiple layers of aluminum, galvanized or stainless steel crimped knitted mesh, enclosed in a channel frame with either expanded metal or welded metal fascias front and back. Handles can be incorporated to the frames to aid removal for cleaning and replacement. There are many stock sizes available in a range of materials, however low cost custom made sizes are easily catered for.
