Yarn Wound Filter Element

Application area Filtration in chemical and pharmaceutical industries, cosmetics industry,... more

Application area

Filtration in chemical and pharmaceutical industries, cosmetics industry, petroleum industry, food processing industry, paints and coatings industry, electroplating technology, water purification, nuclear power plant construction, as well as filtration of photographic fluids.

Product specification

Excellent dirt uptake due to strongly structured, helically wound filter yarn

Large yarn assortment allows use with many media

High flow rate throughput combines great economic efficiency

Selected quality yarns are wound on a retaining core by a special winding mode. The structure of the winding is carried out in such a way that the spiral tapers off inwards. By this special winding mode the yarn construction guarantees regularity of the filter structure and high dirt uptake capacity.

Depending on the application area the filters are to be manufactured with yarns made of cotton, PP (polypropylene) or viscose and retaining cores made of PP (polypropylene) and stainless steel.

Application examples based on material PP (polypropylene):

For filtration of industrial water, drinking water, mineral water, condensates, deionized water, aqueous solutions (pH 3-9), electroplating baths (pH 3-9), electroplating baths (pH <3), fluoroborate baths, cyanide baths (alkaline), pyrophosphate baths, acids and alkalis (pH 0-14), hydrochloric acid, sulfuric acid, phosphoric acid, hydrofluoric acid, nitric acid, pickling and phosphatizing baths, radioactive solutions, photochemical baths, lyes, hydraulic oils, heating and diesel oils, petrols, lubricating oils, alcohols, glycerols, chlorine, hydrogen chloride, hydrogen fluoride, and other aggressive gases.

Application examples based on material cotton:

For filtration of industrial water, drinking water, mineral water, condensates, deionized water, aqueous solutions (pH 3-9), electroplating baths (pH 3-9), tin baths (alkaline), pyrophosphate baths, radioactive solutions, photochemical baths, solvents, degreasing baths, freons, hydraulic fluids, heating and diesel oils, petrols, lubricating oils, edible oils, edible fats, alcohols, glycerols, aggressive gases.

The filter elements fit following housings:
