The knitted wire mesh could be used for rangehood filters. Framed knitted wire mesh elements known as rangehood filters are installed above cooking ranges 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 mesh rangehood filters offer a low resistance with maximum efficiency up to 98%. A mesh pad is designed with a specific thickness, density and wire size to optimize separation efficiency and flow capacity for expected process conditions. Knitted wire mesh pads can often be replaced re-using the support channel frame and grid over again.

It is made from multi-layers of aluminium, 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.
