What cartridge lengths are available?

Standard lengths are typically 10\", 20\", 30\", and 40\". Other lengths may be available depending on the product design and customer requirements.

What are the common connection types?

Common connection types include DOE, SOE, 222, 226, flat end, and fin end configurations. The connection should be selected according to the filter housing design.

How often should the cartridge be replaced?

Replacement frequency depends on feed water quality, operating pressure, flow rate, and contaminant load. The cartridge should be replaced when pressure drop increases significantly or filtration performance decreases.

Is the cartridge resistant to chemicals?

Polypropylene pleated filter cartridges generally provide good resistance to many chemicals. For applications involving strong chemicals, the compatibility of the filter media and seal materials should be confirmed before use.

What applications are suitable for this cartridge?

Pleated filter cartridges are commonly used in RO pretreatment, desalination, industrial water treatment, petrochemical process water filtration, food and beverage processing, and general liquid filtration applications.

Key features

High-Efficiency Filtration: Capture suspended solids and fine particles effectively, helping protect downstream equipment and maintain stable water quality.

Reliable Flow Performance: The pleated design provides a larger filtration area, supporting consistent flow while reducing pressure drop.

Reduced Cartridge Change Frequency: High dirt-holding capacity helps extend service life, minimizing maintenance interruptions in continuous water treatment systems.

Improved RO Protection: Removes sediment and contaminants before RO membranes, helping reduce fouling and improve overall system efficiency.

Large Filtration Area: The pleated structure provides significantly more filtration surface than standard cartridges, helping improve dirt-holding capacity.

Extended Service Life: Durable filter media supports longer operating cycles, reducing replacement frequency and lowering maintenance costs.

Ideal for Desalination Pretreatment: Suitable for seawater pretreatment systems, helping protect RO membranes from suspended solids and particulate matter.

Reliable for Industrial Water Treatment: Supports stable filtration performance in petrochemical plants, industrial water systems, and process water applications.

Greater Dirt-Holding Capacity: Compared with standard sediment filters, pleated filter cartridges can retain more contaminants before replacement is required.

Lower Operating Cost: By combining high filtration efficiency with extended service life, pleated cartridges help reduce downtime and maintenance expenses.

AI-Powered supplier vetting

SummaryThe supplier operates in screen-mesh processing and manufacturing, luggage and bags, related equipment and accessory sales, and general import/export activities. It has documented procedures and records for corrective actions and complaint handling, quality assurance, finished-product inspection instructions, inventory capability, and valid manufacturing-capacity contracts with affiliated subcontractors. Customization is offered from samples and designs, including full, minor, and flexible customization, but no 3D software design service is provided, no new product was reported in the past year, and R&D audit documentation was unavailable. Production inspection is based on random inspection by two quality inspectors. The supplier has no overseas warehouse, showroom, agent, or branch, although it has participated in FiltXpo 2025. Financial credibility and customer-case strength cannot be determined from the provided information.

Supplier typeThe supplier’s stated scope covers screen-mesh processing and manufacturing, sales and technical services for screen meshes, mechanical equipment and accessories, rubber and plastic products, household items, luggage and bags, and import/export activities. This supports classification as a manufacturer and trading/service supplier rather than a narrowly specialized single-product entity.

After-Sales capabilityThe supplier has clear procedures and followed records for corrective and preventive actions and customer complaints, plus in-stock service capability. However, it lacks overseas warehouses, showrooms, agents, and branches; therefore, documented service-process capability is evident, but overseas service coverage is limited.

R&D capabilityThe supplier reports no new products in the past year and has no R&D design-input, output, review, verification, or validation documents available for audit. Although the general manager cooperates with the factory on customer-requested product development and AutoCAD is listed, the available evidence does not establish strong, documented innovation capability.

Production capacityProduction-related evidence includes two quality inspectors, random finished-product inspection, standardized inspection instructions that are uniformly followed, quality assurance in quality-control processes, inventory capability, and valid manufacturing-capacity contracts with affiliated subcontractors. These explicit controls support production capability, although the slices do not state production volume or capacity.

Customization capabilityThe supplier explicitly offers customization from samples and designs, full customization, minor customization, and flexible customization. The general manager is also described as cooperating with the factory to develop products according to customer requirements, while the absence of 3D software design service limits the available design-support format.

Product Q&A

Q:What is a pleated filter cartridge?

pleated filter cartridge is a depth or membrane filtration element with a pleated structure that increases the filtration surface area. It is commonly used for removing suspended solids and fine particles from water and industrial liquids.

Q:What micron ratings are available?

Common micron ratings include 0.1, 0.22, 0.45, 1, 3, 5, 10, 20, 50, and 100 microns. The appropriate micron rating depends on the application and the level of filtration required.

Q:Is this cartridge suitable for RO pretreatment?

Yes. Pleated filter cartridges are widely used in RO pretreatment systems to reduce sediment and particulate matter before water enters the RO membranes.

Q:Can it be used in desalination plants?

Yes. Pleated filter cartridges are suitable for desalination pretreatment applications, where they help remove suspended solids and protect downstream equipment and RO membranes.

Q:What materials are commonly used?

Common filter media include polypropylene (PP), PES, and PTFE. Support layers, cores, cages, and end caps are often made of polypropylene (PP).
