features
✅ Double-layer PTFE membrane structure
Adopting 0.2 micron polytetrafluoroethylene (PTFE) double-layer composite membrane, the super hydrophobicity ensures 100% interception of aerosols and microorganisms, and outputs sterile gas.
✅ Unique single opening design
The integrated end cap structure optimizes airflow distribution, avoids bypass risks, and is suitable for flexible system layout of forward/reverse bidirectional installation.
✅ Industrial-grade steam tolerance
Supports in-situ bidirectional steam sterilization (SIP):
Resistant to repeated 121°C forward and reverse steam sterilization
Maintains filtration integrity in the presence of high humidity/liquid water
Quality
- Each AB3PFR7WH4 membrane filter is 100% integrity tested before shipment.
- Manufactured under an ISO 9001 certified quality management system.
Applications
- Fermentation Inlet & Exit Air/Gases: Sterile air/O2 supply to bioreactors and sterile venting off-gas.
- Tank Venting: Sterile filtration of vent gases on storage tanks, reactors, and transfer vessels (e.g., WFI, buffers, media, bulk drug substance).
- Purified Process Gases (N2, O2, CO2): Sterile filtration point-of-use for gases entering sensitive processes or filling lines.
- Oxygenation/Sparging: Sterile filtration of gases used to aerate or mix liquids.
- Cleanroom Pressurization: Supplying sterile air to critical environments.
- Aerosol Filling Lines: Protecting the filling environment.
