Name: Filter Cartridge
Brand: JX Filtration

Description

JX Filtration offers a full range of filter cartridges from 0.1 micron ultra-fine elements to 100 micron coarse pre-filters, in melt-blown, pleated, wound, and sintered constructions, with flexible customization options to suit various flow rates, temperatures, and chemical environments across water treatment, chemical, pharmaceutical, food, and electronics applications—precise, consistent, and economical to operate.

A filter cartridge is the replaceable filter element that performs the actual particle retention inside a cartridge filter housing. Unlike the housing, which is a reusable pressure vessel, the cartridge is a consumable component designed to be swapped out when differential pressure rises or the service interval is reached. Cartridge construction directly determines filtration precision, dirt-holding capacity, flow characteristics, and chemical compatibility—making element selection the single most important decision in cartridge filtration.

Working Principle

Depth Filtration (Melt-Blown & Wound): Melt-blown PP cartridges are formed from continuous microfibers randomly bonded into a cylindrical matrix. The fiber density increases progressively from the outer surface to the core, creating a gradient pore structure. Particles are captured throughout the entire depth of the media rather than only at the surface, which is why these cartridges hold far more contaminant than surface-type media before reaching terminal pressure drop. Wound cartridges achieve a similar effect by winding yarn in a precisely controlled pattern across a porous core.
Surface Filtration (Pleated & Membrane): Pleated cartridges use a flat sheet medium—PP, PTFE, PES, or nylon—folded into deep pleats to pack a large surface area into a compact element. Filtration occurs primarily at the medium surface, making these elements ideal for absolute-rated retention and sterile-grade applications such as 0.22 μm and 0.1 μm sterilization.
Sintered Metal Filtration: Sintered stainless steel and titanium cartridges are formed by fusing metal powder or fiber into a rigid, porous structure. These elements rely on both surface and depth capture, and are chosen where reusability, high temperature, or aggressive chemical resistance is required.

Advantages

Precise, repeatable micron ratings – Available from 0.1 to 100 microns with tight tolerance control for consistent batch-to-batch performance
High dirt-holding capacity – Gradient density melt-blown and wound structures capture contaminant throughout the media depth, extending changeout intervals
Broad chemical compatibility – PP, PTFE, PES, nylon, stainless steel, and titanium options cover acids, alkalis, solvents, and high-purity process streams
Wide temperature range – PP elements rated to 80°C; PTFE elements continuous to 260°C with steam sterilization capability up to 140°C
Low extractables and clean operation – High-purity grades available for pharmaceutical, WFI, and electronics applications, minimizing media migration and downstream contamination
High surface area in compact form – Pleated construction packs substantial filtration area into a small element, reducing housing size and changeout frequency
Reusable options available – Sintered metal cartridges can be cleaned and reused, lowering long-term consumable cost in high-temperature or corrosive service
Standardized interfaces – Flat head, 222, 226, and threaded configurations fit most common housings without modification
