When customers buy hydraulic oil filter elements, they generally hesitate whether to want domestic glass fiber or imported glass fiber? Because the two are basically invisible from the outside, how to distinguish the filter materials between the two, here Lifelt filter solemnly discloses:

From the following points:

    1. In terms of performance:

        Comparing parameters such as precision, flow rate, air permeability pressure difference, and filtration efficiency, after testing and inspection, the imported glass fiber is far superior to the domestic glass fiber.

    2. In terms of price:

        Domestic glass fiber is about 70 yuan per kilogram, and imported glass fiber is about 300 yuan per kilogram.

    3. In terms of structure:

       Imported glass fiber is extracted from pure glass fiber, and its texture is fragile, so a layer of camellia paper is added inside and outside, so the color is a bit yellowish. Domestic glass fiber is artificially synthesized and relatively whitish.

    4. From the appearance:

       Imported glass fiber: It is composed of two layers of non-woven fabric and one layer of glass fiber filaments. The layers are distinct. The filter layer is thin and easy to break the water bag in the oil. The accuracy is generally 1-25 microns

       Domestic glass fiber: It is composed of two layers of non-woven fabric and three layers of glass fiber filaments. The layers are not obvious. The thickness of the filter layer is not easy to break the water bag in the oil. The accuracy is generally 1-100 microns

  So when you buy glass fiber filter elements, you must recognize the difference between domestic glass fiber and imported glass fiber!

     Imported fiberglass brands mainly include: American HV, German Rand, etc.

     Domestic fiberglass brands mainly include: Nanjing Fiberglass Institute and Chongqing Regeneration, etc.
