Cobetter AET, APTF series filter cartridges are composed of PTFE membrane and fluoroplastic core, support and seal material, making it all-teflon, and especially suitable for the filtration of strong chemical corrosion at high temperature.
Applications
- Hydrofluoric acid, Nitric acid, Sulfuric acid, Hydrochloric acid and other acids filtration
- Various kinds of high temperature gas filtration over 100°C
- Chloroform, Dimethyl, Isopropyl alcohol and other aggressive solvents filtration
- Not suitable for strong alkali filtration
- Not resistant to steam sterilization
