Overview
The Deepflow CYTANKPE02 Water Tank Air Filter is an engineered component designed for integration into ultra-pure water (UPW) distribution systems, specifically installed at the vent port of storage tanks in laboratory-grade and pharmaceutical-grade water purification installations. It functions as a critical barrier against ambient airborne contamination—preventing ingress of particulates, microorganisms, hydrocarbon vapors, and moisture during tank pressure equilibration. Unlike passive vent caps, the CYTANKPE02 employs a hydrophobic, PTFE-based membrane with validated bacterial retention efficiency (≥99.9999% for ≥0.2 µm particles per ISO 13408-1), ensuring that atmospheric air entering or exiting the tank during fill/drain cycles remains sterile and particle-free. Its design conforms to core principles of Good Manufacturing Practice (GMP) and ISO 25197 for compressed air and gas filtration, adapted for liquid-phase water system integrity.
Key Features
- Hydrophobic expanded polytetrafluoroethylene (ePTFE) membrane with nominal pore size of 0.2 µm, certified for microbial retention in accordance with ASTM F838-22
- Integrated dual-stage filtration architecture: pre-filter layer removes coarse dust and fibers; final membrane provides absolute barrier against bacteria, yeasts, and molds
- Autoclavable housing (up to 121°C, 20 min, saturated steam) compatible with routine SIP (Steam-in-Place) protocols used in UPW system validation
- Low-pressure drop design (<0.1 bar at 10 L/min airflow) minimizes backpressure effects on tank venting dynamics and prevents siphoning or vacuum lock
- Stainless steel 316L or reinforced polypropylene housing options available—chemically inert to ultrapure water (resistivity ≥18.2 MΩ·cm), TOC leachables < 1 ppb
- ISO-KF (QF) or NPT threaded interface for standardized mounting on tank manways; optional integrated pressure relief valve (set point: 0.5 bar)
Sample Compatibility & Compliance
The CYTANKPE02 is validated for use with Type I ultrapure water (ASTM D1193-20, ISO 3696 Class 1) and WFI (Water for Injection, USP ) storage applications. It maintains integrity under continuous exposure to deionized water vapor, ozone-treated air, and nitrogen blanketing environments. The filter complies with ISO 9001:2015 manufacturing controls and supports compliance with FDA 21 CFR Part 11 requirements when paired with audit-trail-capable monitoring systems. Documentation includes Certificate of Conformance, Extractables Report (per USP ), and Bacterial Challenge Test Report (Bacillus subtilis spores, 10⁷ CFU/cm² challenge). It is suitable for GLP and GMP-regulated laboratories performing analytical chemistry, cell culture, and biopharmaceutical process water qualification.
Software & Data Management
While the CYTANKPE02 is a passive mechanical device without embedded electronics, its operational status is monitored indirectly through upstream/downstream pressure differential sensors and integrated system SCADA platforms. Compatible with industry-standard laboratory informatics systems—including LabVantage LIMS, Thermo Fisher SampleManager, and Siemens Desigo CC—via Modbus RTU or 4–20 mA analog output interfaces (when paired with optional digital pressure transducer kits). Filter lifetime tracking is supported via predictive maintenance algorithms using cumulative airflow and delta-P trends, aligning with ISO 13485 risk management frameworks for medical device water systems.
Applications
- Final vent filtration for stainless steel UPW storage tanks in central purification plants serving analytical labs and cleanrooms
- Protection of recirculating loops during intermittent operation or shutdown phases to prevent biofilm seeding from ambient air
- Ozone-offgas scrubbing support in advanced oxidation UPW systems, where residual ozone must be decomposed before atmospheric release
- Nitrogen-purged tank headspace maintenance in semiconductor fab water systems requiring sub-ppb TOC and silica control
- Backup filtration for redundant tank vent lines in multi-tank pharmaceutical water distribution networks (e.g., purified water + WFI dual-system architectures)
FAQ
Is the CYTANKPE02 suitable for WFI (Water for Injection) storage tanks?
Yes—when installed with appropriate validation documentation and maintained per USP , it meets microbial retention and extractables requirements for WFI system venting.
Can this filter be sterilized using gamma irradiation?
No—gamma exposure degrades ePTFE membrane morphology; steam sterilization (121°C, 20 min) or ethylene oxide (EtO) processing is recommended.
What is the recommended replacement interval?
Filter life depends on ambient air quality and system duty cycle; typical service life ranges from 6–24 months, with mandatory replacement after any documented integrity test failure or pressure differential exceeding 0.3 bar.
Does Deepflow provide installation qualification (IQ) and operational qualification (OQ) templates?
Yes—validated IQ/OQ protocols compliant with Annex 15 and EU GMP guidelines are available upon request for qualified end-users.
