Perforated filter made of perforated sheet, can be classified into perforated cylinder filter, perforated basket filter, perforated cone filter and perforated tube filter. Generally it is made of stainless steel, carbon steel, aluminum or copper sheet and the hole shape is round or square. With accurate filtration rate, perforated filter can filter a large variety of fluids and retain almost any size solids. With high mechanical strength, perforated filter is mainly used in petroleum, chemical industry, pharmacy, food making filtration and sewage water filtration, etc.
