✅ ePTFE ultrafine membrane (0.1–1.0 µm) - Precise particle and microbial retention with high void volume for extended service life.
✅ Broad chemical compatibility - Long service life in aggressive solvents, acids and bases; reduces replacement frequency and containment risk.
✅ Hydrophobic & modified-hydrophilic options - Optimise for gas/venting (hydrophobic) or aqueous sterilizing filtration (hydrophilic treatment) without changing cartridge geometry.
✅ Rigid support (PP or 316L stainless steel core/cage) - Minimal deformation under pressure, compatible with standard housings and high differential pressure applications.
| Air Flow Rate System pressure at 30 psig, 65°F (18°C) |
Air Flow Rate System pressure at < 10 psig (vent), 65°F (18C). Outlet open to atmosphere |
Water Flow Rate This chart represents the typical water flow per 10" cartridge length. Cartridges are tested in water at ambient tem-perature. Data may be extrapolated for multiple lengths, but as flow rate increases, AP of the housing becomes more apparent. |
