Gas & vent filtration
TEFguard® PTFE membrane filters
Hydrophobic PTFE membrane filter configurations developed for compatible gas and vent filtration requirements.
Product overview
TEFguard uses a hydrophobic PTFE membrane format intended for suitable gas and vent applications. Configuration selection should consider the gas composition, moisture exposure, required retention, flow, differential pressure, temperature, sterilization method and connection requirements.
Filter-size configurations
Select the nominal filter length according to the required effective filtration area and process demand.
| Nominal filter length | Effective filtration area |
|---|---|
| 5 in | 0.37 m² / 3.98 ft² |
| 10 in | 0.74 m² / 7.97 ft² |
| 20 in | 1.48 m² / 15.94 ft² |
| 30 in | 2.22 m² / 23.91 ft² |
Filtration area values are nominal. Confirm the selected configuration and current controlled specification before ordering.
