Introduction: PP Folding Filter Cartridge
TANVI2024-07-12 TANVI282
PP folding filter cartridge, also known as polypropylene folding filter cartridge, is a filtering product made by folding ultra-fine polypropylene fiber membrane and non-woven fabric or (wire mesh) inner and outer support layers. The center rod and end cap of its shell are processed and formed using hot melt welding technology, without any adhesive, and have the characteristics of no leakage and no secondary pollution. The following is a detailed introduction to PP folding filter cartridge:


Product Features


High filtration accuracy: The filtration accuracy of PP folding filter cartridge is usually between 0.1 μ m and 50 μ m, which can effectively filter suspended solids, particles, colloids and other impurities in water.


Large area filtration: The folding structure significantly increases the membrane filtration area of the filter element, improving filtration efficiency and pollutant holding capacity.


Low pressure difference: Due to the large filtration area, the resistance of water flow is small, resulting in a lower pressure difference, which is beneficial for reducing energy consumption.


Long service life: Due to its strong dirt holding capacity, PP folding filter cartridges have a relatively long service life.


Good chemical compatibility: The single pure polypropylene material makes it easy to determine the chemical compatibility of the filter element, suitable for filtering strong acids, strong bases, and organic solvents.


High temperature resistance: PP material has good high temperature resistance, generally able to withstand temperatures ranging from 4 ° C to 80 ° C.


Easy installation: Usually designed with 222 or 226 ports, it is easy to install and replace, and does not require tools to complete the operation.

application area 


PP folding filter cartridge is widely used in multiple fields due to its excellent performance:


Water treatment industry: used for purifying drinking water, industrial water treatment, electronic industry water, etc., effectively removing pollutants such as particles, impurities, bacteria, etc. from water.


Food and beverage industry: Due to the non toxicity and high temperature resistance of PP material, it is commonly used for liquid filtration in food and beverage production to ensure product quality and safety.


Chemical industry: used for solvent filtration, acid-base solution filtration, liquid separation and other processes in chemical production to ensure the stability of the production process and product quality.


Pharmaceutical industry: In the field of pharmaceuticals, it is used to ensure the purity and sterility of products in the production process of medicines such as potions, injections, and biological products.


Electronic industry: used for water treatment in semiconductor manufacturing, electroplating and other processes, efficiently removing small particles and microorganisms.


During use, attention should be paid to avoiding exceeding the working pressure limit of the filter element (generally not exceeding 0.3Mpa) to avoid damaging the filter element.


Strict adherence to standards is required during sterilization operations to reduce damage to the filter element caused by high-temperature sterilization steam.


Above all, PP folding filter has become one of the indispensable and important filter types in industrial production and daily life due to its excellent filtration performance, wide chemical compatibility, and convenient installation method.
