Pleated PP Filter Cartridge 5 Micron 40 Inch: High Flow Pleated Polypropylene Cartridge For Industrial Precision Water Treatment
Introduction:If you are searching for reliable Pleated PP Filter Cartridge 5 Micron 40 Inch for industrial process water filtration, chemical liquid clarification and RO system pre-treatment, this pleated polypropylene filter cartridge delivers stable 5 micron particle retention performance. Its folded media design greatly expands the effective filtration area, bringing higher flow rate and larger dirt holding capacity compared with string wound filters of the same size. It effectively intercepts fine silt, tiny rust particles, suspended solids and colloidal contaminants, serving as an excellent pre-filter to reduce membrane fouling and protect reverse osmosis and ultrafiltration systems. This glue-free thermal bonded filter element is widely used in food and beverage production, electroplating liquid purification, power plant water systems and general industrial water treatment projects across global markets.

Product Overview
Pleated PP Filter Cartridge 5 Micron 40 Inch is a high-performance disposable pleated filter for medium precision industrial liquid filtration. It is manufactured by folding virgin polypropylene filter media and adopting thermal bonding technology without any adhesive, avoiding secondary contamination from glue dissolution. The pleated media is fixed with PP end caps and a solid polypropylene inner support core. With standard dimensions of 40 inch length, 60mm outer diameter and 30mm inner diameter, it can be directly installed into standard 40-inch filter housings for replacement. Compared with 1μm pleated PP filter, this 5μm grade achieves higher flow and lower pressure drop, while still maintaining reliable fine particle removal capability. Virgin polypropylene material provides good resistance to weak acid and weak alkali, adapting to most neutral and mildly corrosive industrial liquid working conditions.
Working Principle
Pleated PP Filter Cartridge 5 Micron 40 Inch works on outside-in filtration principle. When liquid flows into the filter housing and contacts the pleated PP media, large impurities are trapped on the outer pleated layers. All solid particles larger than 5 micron are intercepted by the dense polypropylene filter medium. The pleated structure spreads liquid over a much wider surface area, slowing clogging and extending service life. Thermal sealed joints prevent liquid bypass and guarantee all fluid passes through the filter media. The sturdy inner core withstands differential pressure and keeps the pleats intact under continuous running, ensuring consistent filtration efficiency during long-term operation.

FAQ
Q1: What is the difference between 5μm pleated PP filter and 5μm string wound filter?
A1: Pleated PP filter has larger filtration area, higher flow and lower pressure drop, no glue contamination risk, but it is disposable. String wound filter can be cleaned and reused multiple times.
Q2: Can this 5μm pleated filter be reused after washing?
A2: It is designed as disposable filter. Once the pleated pores are blocked by colloids or fine particles, washing cannot fully restore filtration performance.
Q3: What is the maximum continuous working temperature?
A3: Continuous working temperature cannot exceed 80℃. Excessive high temperature will deform the pleated media and damage thermal sealing positions.
Q4: Can customized end cap styles be supplied?
A4: Yes, DOE, SOE and other end cap options are available. Multiple micron ratings and lengths can be customized for bulk orders.
