PVDF Pleated Filter Cartridge
OVERVIEW
PVDF (Polyvinylidene fluoride) pleated filter cartridges are high-performance filtration elements designed for applications requiring exceptional chemical resistance, high thermal stability, and superior mechanical strength. These cartridges are widely used in industries such as pharmaceutical, biotechnology, chemical processing, food and beverage, and ultrapure water treatment.
Made from hydrophobic or hydrophilic PVDF membrane and polypropylene components, PVDF pleated cartridges offer excellent resistance to aggressive chemicals, including acids, bases, and solvents. Their pleated design provides high filtration surface area, ensuring long service life and consistent flow rates.

Advantages of Using PVDF Pleated Filter Cartridge
1. Superior Chemical Compatibility
PVDF offers exceptional chemical resistance compared to PES, Nylon, or PTFE membranes. It can filter aggressive acids (like nitric, hydrochloric) and bases (like sodium hydroxide) without degradation.
2. Enhanced Thermal Tolerance
PVDF membranes maintain performance even under elevated temperatures. This makes them suitable for hot chemical processes or autoclave sterilization.
3. Low Binding & Extractables
These cartridges are manufactured in cleanroom environments and exhibit low protein binding and minimal extractables, ensuring that filtrate purity is not compromised—critical in pharmaceutical and electronic applications.
4. Long Service Life
The pleated construction provides high dirt holding capacity and flow rates, reducing maintenance frequency and operational downtime.
How to Choose the Right PVDF Pleated Filter Cartridge
When selecting a PVDF pleated cartridge, consider the following factors:
Filtration Pore Size: Choose 0.22 μm or 0.45 μm for sterile filtration; 1–10 μm for prefiltration or particulate removal.
Fluid Characteristics: Is the fluid acidic, basic, or contains solvents?
Temperature Requirements: Ensure the cartridge supports your system’s temperature.
System Configuration: Match end caps and gasket materials with your housing.

Installation & Maintenance
Installation Tips:
Always pre-flush the cartridge with clean water or compatible solvent before use.
Check the housing seal to prevent leakage.
Ensure compatibility of O-ring material with your filtration fluid.
Cleaning & Reuse:
PVDF cartridges can be sanitized with hot water or chemical agents. However, actual reusability depends on application, contaminant type, and cleaning protocol.
Storage:
Store in a clean, dry environment away from direct sunlight. Avoid freezing.
