Product description

The PTFE Air Filter Cartridge 118x114 is a high-performance hydrophobic air filter element manufactured from premium PTFE membrane material. With dimensions of 118mm outer diameter and 114mm length, this filter cartridge delivers exceptional filtration performance in demanding air and gas purification applications where conventional filter media would degrade or fail.

Made from pure PTFE material, this cartridge boasts exceptional chemical stability, high-temperature resistance, and low extractable properties, effectively intercepting airborne particles, microorganisms, and odor molecules. The naturally hydrophobic PTFE membrane prevents water absorption, making these cartridges ideal for air and gas filtration systems where moisture resistance is critical.

• Naturally hydrophobic PTFE membrane repels moisture and prevents water absorption, ensuring 100% filtration efficiency even in damp environments.
• Exceptional chemical resistance withstands strong acids, alkalis, organic solvents, and oxidizing substances without degradation.
• High-temperature performance operates continuously from -200°C to +260°C, supporting steam and dry heat sterilization.
• Ultra-low extractables – PTFE's smooth, inert surface releases minimal organic or inorganic substances, preventing contamination of high-purity products.
• Pleated design maximizes filtration surface area, delivering high flow rates with low pressure drop and extended service life.
• High filtration efficiency captures ≥99.97% of 0.3μm particles, effectively removing bacteria, viruses, and mold spores from air streams.

When installed in an air or gas filtration system, this custom air filter cartridge effectively removes:

• Fine Particulate Contaminants : Dust, dirt, pollen, and airborne particles down to 0.3 μm.
• Combustion Byproducts : Soot, fly ash, and carbonized particles from high‑temperature processes.
• Metallic Fumes and Oxides : Fine metal particles from welding, cutting, grinding, and metal processing.
• Acid Mists and Corrosive Aerosols : Chemical mists, acid fog, and corrosive gas particulates.
• Microorganisms : Bacteria, mold spores, and biological contaminants in air streams (with ≥0.3 μm rating).
• Process Dusts : Cement dust, mineral fines, chemical powders, and other industrial particulates.
• Oil Mists and Aerosols : Fine oil droplets and hydrocarbon aerosols in compressed air and ventilation systems.
