The diamond mesh air filter net is designed to make air filter inside core. I continue to improve the plastic net design to meet the industry filter develop for many years, so there are about ten kinds of different diamond mesh air filter net in my hand, with the mesh size from 1mm to 1.5mm. Plastic filter net can be used for many applications in the filtration industry and agriculture. Filter mesh net is widely used in the support or protection of filtration media in pleated filter elements and feed spacer mesh in filtration membrane filters. They are usually used both as inner support (core) and as outer protection for filtration cartridges for air, water and/or industrial fluids.
