评分为 4.3（共 5）
Hydrophobic PTFE Filter Cartridge for Air & Gas Filtration
价格范围：$12.00 至 $150.00
Hydrophobic PTFE filter cartridges are engineered for high-performance air and gas filtration, providing excellent particle retention and chemical resistance. Constructed with hydrophobic PTFE membranes, these cartridges repel water and moisture while capturing fine particulates, ensuring clean and dry gas streams for industrial, pharmaceutical, and electronics applications.
| Filter Media | Hydrophobic PTFE |
|---|---|
| Micron | 0.1um, 0.22um, 0.45um, 0.65um, 1um, 5um, 10um |
| length | 10 inch, 20 inch, 30 inch, 40 inch, 60 inch, 70 inch |
| End Cap | DOE, 222/Fin, 222/Flat, 226/Fin, 226/Flat |
Hydrophobic PTFE filter cartridges are specialized elements for air and gas filtration applications where moisture resistance and high filtration efficiency are required. The hydrophobic PTFE membrane prevents water ingress, allowing gases to pass freely while capturing fine particulates, aerosols, and dust.
These cartridges are widely used in compressed air systems, industrial gas filtration, venting of sterile tanks, and electronics manufacturing. The pleated structure increases effective filtration area, providing high dirt-holding capacity and stable flow performance over extended service intervals.
Hydrophobic PTFE cartridges are compatible with standard housings and are available in multiple micron ratings, lengths, and end cap configurations, offering flexible solutions for various industrial and laboratory gas filtration systems.
Manufactured from chemically resistant PTFE and durable support layers, these cartridges maintain structural integrity under harsh chemical exposure and temperature fluctuations, ensuring long-term reliability and safety in critical gas processes.
