A cartridge filter is a filtration system which is available in cylindrical shape and can be installed within a pressure vessel to optimize flow channels and chambers, maximizing the filtration area. These filters are mainly used for removing contaminants and particles from liquids. Filtration cartridges are available in a variety of lengths, diameters, and materials, including woven, nonwoven, and membrane-based options.
Cartridge filters are essential components of liquid filtration systems, designed to remove particles of specific sizes with varying degrees of efficiency. They are rated based on their filtration capability, which can be either nominal or absolute. A nominal filtration rating typically removes around 95% of particles of a given size, whereas an absolute filtration rating ensures a higher efficiency of 99% or more.
Absolute-rated filters, particularly pleated filtration cartridges, are widely used in high-purity applications such as pharmaceuticals, food and beverage production, and ultrapure water systems. Standard micron ratings range from 50 microns for coarse filtration to 0.2 microns for fine, high-purity requirements.
A 5-micron filter is commonly used for general-purpose filtration, whereas a 0.2-micron absolute pleated filter is ideal for critical final filtration stages. Since filtration ratings are determined based on test methods established by each manufacturer, there can be variations in actual performance. For example, a nominal 1-micron filter may correspond to a 15-micron absolute rating under certain conditions.
Absolute ratings are generally assessed using particle removal efficiency percentages or β-values, which compare the number of particles before and after filtration. The removal efficiency of absolute-rated filters typically ranges between 99.0% and 99.9% or higher, ensuring optimal filtration performance.

We offer Cartridge filters which are available in various types, depending on their material of construction (MOC) or their manufacturing process. Each filter cartridge is designed specifically to fulfill filtration requirements. Here are few filtration cartridge systems are listed below:
A metal filter cartridge made from materials like stainless steel due to its robustness and ability to withstand high temperatures allows for repeated use and cleaning, making them ideal for situations where disposable filters are not used. These metal filter cartridges offer long life, chemical compatibility, and durability, providing reliable filtration solutions in applications.
Stainless steel filter cartridges are used for high-temperature applications & made with SS 304, SS 316, and SS 316L materials. These filter cartridges are available in pleated, wrap, or sintered forms to maximize filtration efficiency. Designed with coarser support layers, they prevent damage during the filtration process.
A titanium cartridge filter is a strong and durable filtration component made from titanium. Designed for tough environments and chemicals, these filtration cartridge systems are often used in situations with chloride due to its corrosion resistance.
Polypropylene filter cartridges, equipped with a robust polypropylene microfiber media. They are specifically designed for membrane pre-filter applications. These cartridges can help eliminate a bulk of the solid particles which would otherwise lead to premature clogging of the more expensive membrane cartridges.
Polytetrafluoroethylene (PTFE) filters are high-performance membrane filters known for their chemical resistance. PTFE filters are ideal for sterilizing air and gases, clarifying corrosive liquids, and filtering strong solvents and aggressive fluids.
Polypropylene pleated filter cartridges are available in filtration ratings ranging from 0.2 to 70 microns, they efficiently capture and remove particles from liquids, ensuring cleaner output. Ideal for water treatment and other liquid filtration processes, polypropylene filter cartridges offer exceptional chemical compatibility, high dirt-holding capacity, and long service life.
Glass fiber filter cartridges are filtration materials made from glass fibers or microspheres. They are highly utilized in filtration processes because of their strength, chemical resistance, and capacity to capture particles from liquids and gases. Glass fiber filter cartridges are used in industries such as pharmaceuticals, biotechnology, water treatment, and air filtration. They come in a range of pore sizes and configurations to meet filtration requirements.
Wound filter cartridges, made from polypropylene or glass fibers, meet demanding filtration needs. Produced through a high-speed winding process, these one-piece filters have diamond-shaped tunnels for effective depth filtration. With dirt-holding capacity the fluid passes through the filter media from outside to inside, securely trapping particulates in the filter.

Cartridge filters are used to remove particles and contaminants from liquids or gasses, ensuring cleaner and safer output.
Choosing a filter cartridge involves considering factors like filtration needs, particle size, flow rate, and compatibility with the fluid
The micron size of a filter cartridge refers to the size of particles it can capture, typically ranging from 0.5 to 100 microns.
A filter cartridge is the central component of a filter system. It is inserted inside the filter housing and separates contaminants from the fluid as it flows through the cartridge.
Cartridge filter replacement should be performed within 3-5 years, depending on the filter's performance. Regular monitoring of the filter’s efficiency can help extend the lifespan of the cartridge filter.
