Pleated PP Filter Cartridge 10 Micron 40 Inch: High Flow Pleated Polypropylene Filter Cartridge For Raw Water Pretreatment
Introduction:If you are sourcing Pleated PP Filter Cartridge 10 Micron 40 Inch for industrial raw water filtration, general process liquid purification and RO system pre-treatment, this pleated polypropylene filter cartridge delivers reliable 10 micron particle interception performance. The pleated media greatly expands effective filtration area, bringing higher flow rate and stronger dirt holding capacity compared with same-size wound filter cartridges. It efficiently traps sediment, rust particles, suspended solids and large floc contaminants, acting as an economical pre-filter to reduce fouling risk and protect reverse osmosis and ultrafiltration membrane systems. Adopting glue-free thermal bonding technology, it avoids secondary contamination and is widely used in municipal water treatment, mining water, food and beverage plants, power station circulating water and general industrial liquid filtration projects worldwide.

Product Overview
Pleated PP Filter Cartridge 10 Micron 40 Inch is a cost-effective disposable pleated filter for conventional industrial liquid pre-filtration. It is manufactured by folding virgin polypropylene filter media and using thermal bonding without any adhesive, eliminating the risk of organic substance leaching. The pleated media is fixed with PP end caps and a rigid polypropylene inner support core. Standard dimensions: 40 inch length, 60mm outer diameter and 30mm inner diameter, fully compatible with all standard 40-inch filter housings for quick replacement. Compared with 1μm and 5μm pleated PP filters, this 10μm grade features larger pore size, higher flow rate and lower pressure drop, suitable for removing relatively coarse impurities in raw water. Virgin polypropylene material shows good resistance to weak acid and weak alkali, adapting to most neutral and mildly corrosive industrial liquid working environments.
Working Principle
Pleated PP Filter Cartridge 10 Micron 40 Inch adopts outside-in filtration principle. When liquid enters the filter housing and flows through the pleated PP media, large impurities are trapped on the outer pleated layers. Solid particles larger than 10 micron are intercepted by the polypropylene filter medium. The folded structure distributes liquid over a broad surface area, slowing clogging and extending service life. Thermal sealed joints prevent liquid bypass and ensure all fluid passes through filter media. The sturdy inner core bears differential pressure and keeps pleats intact during continuous operation, maintaining stable filtration efficiency in long-term running.

FAQ
Q1: What is the difference between 10μm pleated PP filter and 10μm string wound filter?
A1: Pleated PP filter has larger filtration area, higher flow rate and no glue contamination risk, but it is disposable. The string wound type can be cleaned and reused multiple times, with lower flow capacity.
Q2: Can this 10μm pleated filter be cleaned and reused?
A2: It is designed for single use. Once pleat gaps 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℃. High temperature will deform pleated media and damage thermal sealing joints.
Q4: Can customized end cap styles be offered?
A4: Yes, DOE, SOE and other end cap options are available. Various micron ratings and lengths can be customized for bulk project orders.
