Oil filter: filter using a special long fiber, deep filter structure is made by the high-density high-pressure treatment, and its features are a filtration accuracy (no less than NAS6 grade) 2. Filtration efficiency, high speed, capacity sewage quantity 3 trap amount of pollutants, dirt holding capacity more than 4 pairs of strong moisture removal, absorption capacity 5 long life cycle, low cost, and lower prices 6. replacement operation, easy to operate, easy to melt jet filter is polypropylene slices through high temperature melting, injection, traction, receiving forming a new generation to replace the traditional filter filter material. Apply a wide range of pre-treatment used in pure water, cooling water, drinking water, laboratory water, boiler water, oil field water and chemical, pharmaceutical, electroplating, printing, paint, photofinishing, fuel, beer, beverage and other industries filtered, and the filter for air purification. Features: (1) filtration efficiency and filtration, the filter pore density, filtration efficiency of 99% or more. (2) filtration resistance, filter flow, pollutant carrying capacity, long life, the goods in the production process, the fiber diameter and the gap is adjustable filter porous outer layer of the inner small large, increasing the flow and pollutant volume, filter clogging and prolong life. (3) self-clean and high water pollution, acid and alkali and organic solvents, corrosion. (4) intensity, import and export filters filter the water pressure exceeds 0.4Mpa not be deformed when the temperature exceeds 90 ℃, the filtration efficiency without compromising Precautions (1) according to the accuracy and the filtered liquid impurities selection filter, two viscous liquids can be filtered, before the class coarse filter, reducing resistance and prolong filter life (typically 3-4 times). (2) Correctly install the filter, if found filtered water pollution, the filter should be carefully examined whether the skew, both ends tightly aligned, pressed. When the pressure reaches 0.2MPa should clean or replace the filter.
