What is 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.
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 0.1ฮผm, 0.2ฮผm, and 1.0ฮผm, PTFE filter cartridges are engineered for high flow, low pressure drop, and maximum filtration performance. The pleated structure increases surface area and enhances the cartridgeโs 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.
