PTFE Pleated Filter Cartridges
Redefining Filtration Standards with PTFE Excellence.
PTFE Filter Cartridges are engineered to meet the highest standards of filtration efficiency and chemical resistance. These cartridges are made from advanced PTFE membranes, providing exceptional durability and performance in the most demanding applications. Designed for sterile filtration of liquids, air, and gases, they are widely used in industries such as pharmaceuticals, biotechnology, electronics, and chemical processing.
What are PTFE Filter Cartridges?
PTFE (Poly Tetra Fluoro Ethylene) filter cartridges are high-performance filtration solutions designed for liquid, air, and gas streams, particularly in applications requiring chemical inertness and sterile filtration. These cartridges are constructed using hydrophobic PTFE membranes, known for their exceptional resistance to chemicals, heat, and corrosion. The unique properties of PTFE make these filters ideal for environments with aggressive fluids, high-temperature operations, and critical applications requiring absolute purity.
Key characteristics of PTFE filter cartridges include:
Hydrophobic Membrane: Prevents moisture obstruction during venting and wet air filtration.
Sterile Filtration: Ensures superior bacterial retention with precisely controlled pore size distribution.
High Flow Rate and Low Pressure Drop: Achieved through advanced membrane design with up to 0.7 m² filtration area per 10" cartridge.
Versatility: Suitable for a wide range of industries, including pharmaceuticals, semiconductors, and chemical processing.
Chemical Compatibility: PTFE is compatible with strong acids, bases, solvents, and other aggressive chemicals, ensuring reliable performance in demanding environments.
How do PTFE Filter Cartridges Work
PTFE filter cartridges utilize a microporous PTFE membrane to trap contaminants. The hydrophobic nature of the membrane allows air and gas to pass through while blocking water and particulates. In liquid applications, the filters ensure that even the smallest particles are retained, providing absolute-rated filtration.
PTFE filter cartridges are typically constructed with:
Filter Media: 100% expanded PTFE membrane.
Support Layers: Polypropylene fibers for additional strength.
Inner and Outer Cores: High-strength polypropylene to enhance durability.
End Caps and Gaskets: Made from materials like silicone, Viton, or EPDM for a secure fit and compatibility with various chemical environments.
