D.King Perforated Metal Filters are 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. According to opening diameter, D.King design the width of plate and punch holes customized by customers. Then these plates are rounded in a spiral or straight strip and welded by argon arc welding. The perforated filter tube surface is processed by electrolytic polishing, galvanization, sandblasting, pickling and passivation. 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. With durable materials and various models, perforated cylinder filters can filter liquids, solids and air or sieve different materials to ensure the purity. With good acid and alkali resistance, sieving tube is a very practical product for filtering ceramic powders, glass materials, plastic materials, soils, mineral aggregates, drug particles, metal powders, etc.

Applications

Perforated metal filter is widely used in petroleum, chemistry, metallurgy, machine, medicine, automobile industries for distillation, absorption, evaporation and filtration processes, so as to eliminate the impurity and foam mixed in the gas and liquid.

Filtration of air: air filters, vacuum filters, filtration of corrosive gases, cage ventilation, etc.

Filtration of liquids: ceramics polluted water cleaning, beverage, disposal of sewage water, filtration of corrosive liquids, beer brewing filter, etc.

Filtration of solid: glass, coal, food processing industry, cosmetics, fluidised beds, etc.
