Econe - Polytetrafluoroethylene (PTFE) Filter Cartridge
A PTFE filter cartridge is a pleated filtration element made from polytetrafluoroethylene membrane, known for its hydrophobic nature, chemical inertness, and thermal stability. These cartridges are primarily used to filter aggressive gases, corrosive liquids, and sterilizing air in industries where conventional filter media may degrade or fail.
- Hydrophobic Membrane Structure: PTFE (Polytetrafluoroethylene) filter cartridges are naturally hydrophobic, ideal for air, gas, and aggressive chemical filtration.
- Excellent Chemical Resistance: Resistant to strong acids, bases, and solvents, making it suitable for harsh environments.
- Sterilizable & Reusable: PTFE cartridges can withstand steam sterilization and multiple cleaning cycles without degrading performance.
- Long Service Life: Pleated design provides high surface area and dirt holding capacity, reducing replacement frequency.
- Customizable OEM Options: We offer various lengths, end caps, micron ratings, and labeling for global distributors and system integrators.
What is PTFE Filter Cartridge
PTFE membrane filters are especially valuable in chemical processing, pharmaceuticals, semiconductors, and food & beverage sectors due to their ability to resist strong acids, alkalis, and solvents. Hydrophobic PTFE prevents water absorption, making these cartridges ideal for air and gas filtration systems.
Available in various micron ratings such as 0.1μm, 0.2μm, and 1.0μm, PTFE filter cartridges are engineered for high flow, low pressure drop, and maximum filtration performance. The pleated structure increases surface area and enhances the cartridge’s dirt-holding capacity.
With long service life, broad chemical compatibility, and sterile processing capabilities, PTFE cartridges are widely adopted in applications where consistent, reliable filtration is essential.
- Superior Chemical Resistance: Withstands aggressive acids, alkalis, and solvents without degradation.
- Hydrophobic Nature: Ideal for air, gas, and vent filtration, preventing water ingress.
- High Thermal Stability: Operates up to 120°C; can be sterilized via steam or autoclaving.
- Pleated Design: Maximizes surface area, reduces pressure drop, and prolongs filter life.
- Low Extractables: Ensures product purity in pharmaceutical and biotech applications.
- Reusable: Capable of multiple sterilization cycles without compromising integrity.
- Wide Micron Rating Range: From 0.1μm to 10μm to fit a variety of critical applications.
- Compatibility: Available in DOE, 222, 226 end cap configurations for standard filter housings.
These features make PTFE pleated filter cartridges an excellent choice for demanding filtration tasks in aggressive environments.
PTFE filter cartridges are suitable for a wide range of applications due to their hydrophobic and chemically inert properties. Common use cases include:
- Gas & Air Filtration: Sterile venting and compressed air filtration in pharmaceutical and food processing environments.
- Chemical Filtration: Acid, solvent, and alkaline liquid filtration in chemical manufacturing and laboratories.
- Semiconductor Industry: Filtration of corrosive gases and ultrapure chemicals used in chip production.
- Biopharmaceuticals: Sterile air, tank vent, and solvent filtration in GMP cleanroom environments.
- Laboratory & Medical: Use in sterilization systems, fermentation tanks, and diagnostic equipment.
Their robust construction and compatibility with harsh fluids make them a go-to solution for high-risk applications.
