    Filter Bag


    The filter bag is mainly used in petrochemical, coatings and paints, biomedicine, automobile manufacturing, food and beverage, industrial dust removal and other fields. It is characterized by a loose fiber structure and a high rate of increase in impurities' capacity.

    Filter Bag Filter Bag

    This fiber material is a compound interception mode, which effectively removes solids and soft particles. Larger impurities are trapped on the fiber's surface. In contrast, fine particles are captured in the filter material's deep layer to ensure that filter bag will not damage due to pressure increase.

    Remarks: the above information is reliable but does not mean that it is a guarantee.
    The user needs to make a test to determine the appropriate filter material.

    Correct Selection of Filter Bag:

    According to the actual requirements of the filtration process, to determine the filtration mode (deep filtration, surface filtration) first, and then choose the filter bag material by Table 2


    According to the filter flow rate, medium viscosity, filter precision, to determine the size of the filter bag by Table 1

    Table 3-Filtration Accuracy

    Filtration products of different materials have different filtration modes, filtration efficiency, and filtration precision. Besides, the filtration efficiency would vary with temperature, viscosity, flow velocity, and filtrate quality. Please select the most suitable filter material according to the actual working conditions.

    Chemical Compatibility of Filter Material

    There are many kinds of filter products with different materials. Different filtrates also have other physical and chemical characteristics. In the process of filtration, Filter material must be compatible with it, without chemical reaction. Furthermore, filter material must also face the same pressure and temperature change as filtrate to maintain its fixed structure. Stable and uniform filtration efficiency can be guaranteed only without aperture change, softening, crack, or effusion.

    NY35411Slightly oleophilic, lyophobic150
    PT21111Oleophobic, lyophobic 260

    In general, for filtrates with a higher polarity such as acid-alkali and salt, polypropylene (PP) will do. For filtrates with lower filtrate such as solvent, polyester (PE) or Nylon (NY) will be the right choice.
