Polypropylene folding filter cartridge is a deep filtration cartridge commonly used for pre filtration, clarification filtration, and terminal filtration of liquids.

Has the following characteristics:

Using ultrafine polypropylene fiber membrane as the filtration medium, without any additives;

Full polypropylene structure, with end caps, shells, and center rods all made of polypropylene material;

Adopting hot melt technology for fusion bonding, that is, PP and PP are fused and bonded without any adhesive;

Has broad chemical compatibility;

It has a series of apertures and multiple interface forms.
