Hydrophobic PTFE Filter Cartridge NWF Series | Gas & Solvent Sterilization Filtration | PUNO Kinda Filtration
Short Description:
Product Overview
PUNO Kinda Filtration R NSS series pharmaceutical-grade filter cartridges are manufactured with Micro-series hydrophilic asymmetric sulfonated PES membrane, featuring broad chemical compatibility (pH 3–11), high flow rate, and long service life. Widely used in biopharmaceutical applications, each cartridge is 100% integrity tested before delivery to guarantee filtration efficiency. It withstands repeated online steam / high-pressure disinfection and fully meets the aseptic requirements of the new version GMP.
Key Features
- High-efficiency Sterilization & Filtration: 100% filtration efficiency in humid gas environment; liquid filter rating down to 0.2μm, gas filter rating single layer <0.01μm, double layer <0.003μm; multiple removal ratings available (0.05-5.0μm) for diverse filtration needs
- Superior Hydrophobicity: Passes water intrusion test, avoids solvent wetting test residues, 3.75x stronger water erosion resistance than ordinary PVDF
- Flexible Structure & High Throughput: Single/double layer options; large effective filter area (single-layer ≥0.6/10″, double-layer ≥0.5/10″); small pressure difference, large throughput, extended service life
- Excellent Chemical Compatibility: Resistant to acids, alkalis and various organic solvents, adaptable to complex industrial filtration media
- Safe & Reliable Quality: 100% integrity tested; USP Class VI plastics certified; filtrate <10mg per 10 inch (69mm) cartridge; endotoxin <0.25 EU/ml
- Durable Sterilization Performance: Withstands over 50 times of repeated steam sterilization under no-load state (121°C, 30mins)
- Traceable Production: Each cartridge is independently numbered, full production batch traceability for quality control
- Stable Sealing: Melting seal method, no medium leakage, reliable filtration effect
Typical Applications
- Pre-filtration and sterilization of gases for storage tanks, respirators and ferment tanks
- Sterilization and particle filtration of organic/inorganic solvents (esters, alcohols, acids, alkalis, etc.)
- Sterilization and filtration of compressed air and various process gases in pharmaceutical industry
- High-purity gas/solvent filtration in food & beverage production (meets food-grade safety standards)
