Unlock Reliable Bioprocessing: Meet the AIREPAC SP Hydrophobic PES Filter
2026-05-28
1. The "Breathability" Challenge in Single-Use Systems (SUS) In biopharmaceutical manufacturing, the reliability of single-use systems hinges on a critical yet often overlooked component: the vent filter. If your system cannot "breathe" properly, you risk pressure alarms, bag rupture, and the loss of entire batches.
2. The Classic Dilemma: PTFE vs. Conventional PES/PVDF Standard vent filters often force you to choose between two evils: PTFE membranes provide excellent hydrophobicity but degrade and leach after gamma/E-beam irradiation; conventional PES or PVDF membranes survive sterilization but fail under high-humidity exhaust conditions, leading to membrane fouling and pressure buildup.
3. Introducing the AIREPAC SP: The Ultimate Solution Feature-Tec’s AIREPAC SP Hydrophobic PES capsule filter is engineered to break this cycle. It is designed specifically to withstand both harsh sterilization processes and demanding high-moisture environments without compromise.
4. Irradiation-Ready & Robust We’ve verified the AIREPAC SP against irradiation doses up to ≤50 kGy. Testing confirms that key performance indicators—including bubble point values and bacterial retention (LRV > 10)—remain unchanged, ensuring seamless integration into your SUS terminal sterilization workflows.
5. Superior Moisture Resistance Performance in high-humidity exhaust environments is unmatched. Even after a 7-day "steam sauna" simulation (40°C humidity), the AIREPAC SP maintained stable air permeability at 0.36-0.37 L/min/cm², showing no signs of condensation or membrane fouling.
6. Low-Pressure Drop Protection Safety is paramount. With an asymmetric pore structure, our filters provide high air flux (200-300 L/min/m² at 17 mbar) while staying safely below the maximum operating pressure limits of single-use bags, preventing the risk of "bag burst" during high-volume exhaust discharge.
7. Proven Compliance & PUPSIT Reliability The AIREPAC SP serves as a steadfast gatekeeper in PUPSIT workflows. With full validation documentation, including ASTM F838 bacterial retention, USP <88> Class VI safety, and robust integrity testing (bubble point ≥1200 mbar), we ensure your sterile process remains a closed, reliable loop.
8. Versatile Options for Your Process Whether you need the G-Series (pre-sterilized by E-beam for immediate lab use) or the R-Series (non-sterile, optimized for integrated assembly and terminal irradiation), the AIREPAC SP is your partner in achieving higher cell viability, batch consistency, and faster speed-to-market.
