Nylon Pleated Filter Cartridge
OVERVIEW
The Nylon Pleated Filter Cartridge is a high-performance filtration solution designed for applications requiring excellent chemical compatibility, high dirt-holding capacity, and precise particle retention. Made with a hydrophilic nylon 6 or nylon 66 membrane, this filter cartridge provides excellent flow rates and superior particle removal efficiency, making it ideal for water filtration, food and beverage processing, electronics, and pharmaceutical industries.
Unlike many other membrane types, nylon membranes are naturally hydrophilic, which eliminates the need for wetting agents that could interfere with sensitive downstream processes. This makes the nylon pleated filter cartridge a preferred choice for applications that demand clean, non-contaminating filtrates.

Application of Nylon Pleated Filter Cartridge
1. Water Treatment
Nylon pleated cartridges are widely used in:
RO pre-filtration
Point-of-use systems
High-purity water applications
Their low extractables and hydrophilic nature ensure that no foreign substances leach into the filtrate, providing stable water quality.
2. Food and Beverage Industry
Ideal for:
Beer, wine, and juice clarification
Bottled water filtration
Syrup and liquid sugar processing
Nylon membranes do not contain wetting agents, ensuring no taste or odor transfer into the beverage.
3. Pharmaceutical and Biotech
Used in:
Aseptic filling
Sterile water for injection (WFI)
Biological and serum filtration
Its ability to undergo integrity testing and sterilization makes it suitable for high-standard pharmaceutical processes.
4. Microelectronics and Semiconductor
The high cleanliness and consistent filtration of nylon filters make them ideal for:
Photolithography rinse water
Process chemical filtration
Etching and stripping solutions
5. Laboratory and Analytical Use
Nylon filters offer precise retention and are used for:
HPLC solvent filtration
Sample preparation
Air/gas filtration in lab setups

How to Choose the Right Nylon Pleated Filter Cartridge
Micron Rating
Select based on the particle size you want to remove. For sterile filtration, use 0.22 µm; for prefiltration, 1–5 µm is typical.Length and Configuration
Match with your existing filter housing – check DOE vs. 222/Fin or 226/Flat configurations.Flow Rate Requirements
Check the flow rate curves provided in the product brochure to select appropriate length and number of cartridges.Chemical Compatibility
Nylon is suitable for most aqueous and organic solutions, but always check compatibility charts for specific acids or oxidizers.Regulatory Compliance
Ensure filters meet required certifications such as FDA 21 CFR, EU food contact directives, or USP Class VI if used in regulated environments.
