Product Introduction

Replacement High Flow Filter Cartridge is a large diameter pleated filter element, specially manufactured as drop-in replacement for well-known branded high flow filter housings in ultrafiltration pretreatment systems. It is engineered to maintain the same outer diameter, length, bayonet interface and micron rating as OEM filter cartridges, so users can swap old filters without modifying existing piping or filter vessels. Common filter media materials are virgin polypropylene and glass fiber, with multiple micron grades from 0.5 micron up to 100 micron available for different raw water quality conditions. Installed before ultrafiltration membrane modules, Replacement High Flow Filter Cartridge intercepts silt, iron rust, suspended solids and colloidal particles from raw water before the fluid flows into UF membranes. Regular replacement of these filter cartridges can reduce membrane fouling risk, extend the service life of expensive ultrafiltration membranes, and lower the frequency of chemical cleaning and system maintenance for the whole water treatment plant.

The core advantage of Replacement High Flow Filter Cartridge lies in its full compatibility and cost-effectiveness. Compared with purchasing original brand spare cartridges, this replacement filter reduces procurement expenditure and shortens long delivery lead times of imported OEM spare parts. A single large-diameter replacement cartridge can handle high liquid throughput, which reduces total cartridge quantity required inside filter housings, saves installation space and simplifies on-site filter replacement operations. When designing gradient prefiltration skids and preparing spare parts inventory, engineers can combine Replacement High Flow Filter Cartridge with PFTM11UNPFA high flow filter cartridge and HFU640HGF100H1 high flow filter cartridge to build multi-stage raw water filtration systems.

Replacement High Flow Filter Cartridge adopts glue-free thermal fusion production process. Filter media, inner support core, outer protective skeleton and end caps are thermally sealed together. This eliminates adhesive dissolution and secondary contamination risk under long-term continuous water flow. The raw filter material is virgin polymer with stable chemical resistance and low fiber shedding rate. Whether you maintain existing running ultrafiltration lines or stock spare filters for newly commissioned water reuse projects, Replacement High Flow Filter Cartridge maintains stable filtration performance while optimizing your operational budget.

Working Principle

Replacement High Flow Filter Cartridge works by combining surface filtration and depth filtration mechanisms. Raw water enters the filter housing and flows radially inward through the pleated filter media from outer layer to inner core. Larger contaminants such as sediment and rust deposits are trapped on the outer pleated surface of filter media. Fine colloids and tiny suspended particles penetrate the multi-layer fiber structure and get captured inside the gaps of filter media.

The pleated structure maximizes the effective filtration area of each replacement cartridge. Pollutants are evenly distributed on the whole filter medium surface, slowing down surface clogging and delaying the rise of differential pressure between filter inlet and outlet, which greatly improves dirt holding capacity. When the inlet and outlet pressure difference reaches the preset threshold, filter media is saturated with trapped impurities, and site operators need to shut down the system and install a new Replacement High Flow Filter Cartridge.

This replacement filter cartridge forms the primary protective barrier for ultrafiltration membranes. Without timely filter replacement, fine solid impurities in raw water will scratch membrane surfaces, block membrane pores and cause irreversible fouling of UF membranes. When used in series with PFTM11UEPFA213 high flow filter cartridge to realize multi-stage combined prefiltration, the long-term stable operation of ultrafiltration equipment will be significantly guaranteed. It is important to note that Replacement High Flow Filter Cartridge can only remove solid particulate pollutants, it cannot remove dissolved ions, so it only provides mechanical prefiltration protection before ultrafiltration membrane units.

Technical Parameters

Quality Control

Every batch of Replacement High Flow Filter Cartridge undergoes full-process production inspection and finished-product performance testing before shipment. Raw material inspection is performed for filter media, support cores and end caps to guarantee stable batch-to-batch quality consistency. During manufacturing, sampling inspections cover pleating uniformity, medium tensile strength, thermal sealing integrity and end cap bonding performance.

Finished product tests include bubble point integrity test, cyclic pressure impulse test, flow pressure drop test and particle retention efficiency test. Defective filters with medium cracks, poor sealing or loose structures will be fully screened out. The glue-free thermal fusion sealing eliminates adhesive leaching risk that may contaminate process liquid. The filter medium maintains stable structure and low fiber shedding rate under continuous liquid flushing.

All products comply with strict industrial filtration quality management standards. Each Replacement High Flow Filter Cartridge is individually packaged to avoid dust and particle contamination during storage and transportation. Complete technical datasheets and dimension drawings are supplied for engineering design, spare part BOM creation and quotation reference. Before installation, technicians should inspect the O-ring and filter interface to ensure perfect sealing and prevent bypass leakage.
