Polypropylene pleated filter element is a depth filter element, which is usually used for preheating, clarifying filtration and terminal filtration of liquids. It has the following characteristics: ultra-fine polypropylene fiber membrane is used as the filter medium, low pressure difference, high flux, good filtration accuracy, low economic cost, all polypropylene structure, end cap, shell and center rod are all made of polypropylene Material; sintered by hot-melt process, that is, PP and PP are melted and bonded without any binder; it has a wide range of chemical compatibility; it has a series of apertures and a variety of interface forms.

Features of pleated filter element

Made of 100% polypropylene without any adhesive, minimizing leachables from the filter cartridge itself.

Excellent chemical compatibility, suitable for filtration of strong acids, alkalis and organic solvents.

The filter membrane is deep filtration, with strong dirt holding capacity and long service life.

Good high temperature resistance, can withstand repeated high temperature and high pressure sterilization, or continuous use at high temperature.
