| Feature | Benefit |
| Dual-Layer PTFE Membrane | Superior hydrophobic properties repel water, maintaining filtration integrity in saturated gas streams. Prevents membrane wet-out. |
| Pleated Design | Maximizes filtration area (Up to 5.8 m²) in a single open-ended cartridge. Extends service life & reduces change frequency. |
| Steam Tolerance | Withstands 300+ SIP (Steam-in-Place) cycles at 130°C (266°F), forward or reverse flow. Ensures long-term durability in CIP/SIP systems. |
✅ Aseptic process for biopharmaceuticals: exhaust of fermentation tanks, protection of freeze dryer vacuum pumps, protective gas filtration in aseptic filling areas
✅ Food and beverage gas safety: aseptic filtration of carbonated beverage CO₂, exhaust of beer fermentation tanks, nitrogen packaging gas source treatment
✅ Chemical process safety: filtration of explosion-proof pressure relief ports of reactors, nitrogen sealing gas treatment of flammable solvent storage tanks
✅ Waste treatment and biogas: dehydration and sterilization of landfill gas, terminal purification of biogas after desulfurization

Q: Can this pleated membrane filter cartridge handle oil-laden compressed air?
A: Yes. PTFE's oleophobic properties repel aerosols. For >0.01 ppm oil, pair with coalescing pre-filter.
Q: How often should I replace the AB1PFR7WH4 membrane filter cartridge?
A: Typical lifespan: 12-24 months. Monitor ΔP (replace if >70% initial value) or validate via steam cycles.
Q: Is it compatible with ozone or aggressive gases?
A: PTFE is chemically inert. Validated for O₃, Cl₂, SO₂. Confirm concentration limits with our engineers.
