PP pleated filter cartridge

PP pleated filter cartridge is constructed by 100% polypropylene media providing a wide range of chemical compatibility.
PP pleated cartridge made of 2-3 layers of membranes. The multi layer membrane structure enables graded filtration pore size and increase the dirt holding capacity of the cartridge.
With rigid outer cage and strengthened inner core, the pp pleated filter cartridge can hold higher operating pressure.
Polypropylene filter cartridges are precisely manufactured for use in critical filtration applications within food, pharmaceuticals, biotech, dairy, beverages, brewing, semiconductor, water treatment & other demanding process industries.

About production process of pp pleated filter cartridges:
-Making cartridge pleats: Using filter paper pleating machine to make filter cartridges pleats
-Length cutter/controller: Using filter cartridge length cutter to cut/trim off the pleats.
-Welding middle seam: Using middle seam welder to do middle seam thermal welding of filter cartridges paper
-Cartridge shaping: Putting filter membrane with correct length into the outer cage (plastic shell) with inner core inside of the membrane to keep pleated filter cartridge have initial shape.
-End cap welding: Using cap welder to welding cap onto both ends of filter cartridges
-Fitting end welding: using pleated filter cartridge fitting end welder to weld different types of fitting ends together with both ends of pleated cartridges and form one complete piece of pleated filter cartridges. The different ends types include: flat cover, fin, DOE215/220/222/226, M20/30 thread and other.
-Length jointing/connecting: for 20”/30”/40” long pleated filter cartridges, normally using pleated filter cartridge length connecting welder to weld  2/3/4 pieces of 10” pieces together to complete 20”/30”/40” long pleated filter cartridges.
