Specifications

String Wound Filter cartridge:
1) Three kinds of materials PP otton.Glass fiber
2) Available in retention ratinge of 1-100

                 Widely-used Cotton String Wound Filter Cartridge for Water Purifier

♦Introduction:

PP String Wound Filter Cartridge is stringed by the 100% food grade Polypropylene thread symmetrically.  The filter cartridge contains no wetting agents, solvents, antistatic agents or binders, its function is similar to the PP sediment filter, while it is steadier.  Each micron rate has string pattern to ensure the filtration effect.  This filter cartridge is suitable for the various size and filtration in the industrial water treatment, apply to liquid filtration in the field of petroleum, chemical, electronic, electroplating, medicine and food production.  According to the requirements, various size and filtration precisions are available for option.
