Overview
The Deepflow CYTANKPE01 Water Tank Air Filter with CO₂ Adsorbent is a dedicated purification module engineered for integration into ultra-pure water (UPW) systems—specifically designed to protect storage tanks from atmospheric contamination. It operates on the principle of controlled gas-phase filtration: ambient air drawn into the water reservoir during level fluctuations passes through a dual-stage media bed comprising high-efficiency particulate arrestor (HEPA)-grade hydrophobic membrane and a chemically impregnated CO₂ adsorption layer. This configuration prevents ingress of airborne particles (>0.2 µm), microorganisms, volatile organic compounds (VOCs), and—critically—carbon dioxide, which otherwise dissolves in ultrapure water to form carbonic acid and elevate conductivity, compromising resistivity (≥18.2 MΩ·cm at 25 °C) and total organic carbon (TOC) specifications per ASTM D5127 and ISO 3696 Class 1.
Key Features
- Integrated dual-function design: simultaneous particulate exclusion and CO₂ sequestration in a single compact housing
- Hydrophobic PTFE membrane filter rated at ≥99.999% efficiency for particles ≥0.2 µm (tested per ISO 14644-1 Class 5 cleanroom requirements)
- CO₂ adsorption media based on potassium hydroxide–impregnated activated alumina, validated for >95% CO₂ removal at 400 ppm inlet concentration and 0.5–2.0 L/min flow rates
- Pressure-relief venting mechanism compliant with ASME B31.9 for low-pressure fluid systems; maximum allowable backpressure: 0.1 bar
- Reusable stainless steel 316L housing with EPDM gasket seals; compatible with SIP (steam-in-place) cycles up to 121 °C for 30 minutes
- Visual service-life indicator window showing colorimetric transition of spent CO₂ media (blue → pink) per USP guidance
Sample Compatibility & Compliance
The CYTANKPE01 is intended exclusively for use with Type I ultrapure water systems conforming to ISO 3696:1987, ASTM D1193-20, and CLSI EP22-A2 standards. It is validated for compatibility with deionized (DI), reverse osmosis (RO), and electrodeionization (EDI)-treated feed streams. The unit meets material biocompatibility requirements per USP and cytotoxicity testing. All wetted components comply with FDA 21 CFR Part 177 for indirect food additives and are non-leaching under continuous exposure to UPW at pH 5.5–7.0. Documentation includes full traceability of raw material certifications (e.g., CoA for alumina substrate, DoC for membrane integrity testing), supporting GLP/GMP audit readiness.
Software & Data Management
As a passive mechanical filtration device, the CYTANKPE01 does not incorporate embedded electronics or digital interfaces. However, it is fully interoperable with industry-standard UPW system monitoring platforms—including those from ELGA, Sartorius, and Pall—via external pressure differential sensors and optional analog 4–20 mA output modules (sold separately). Maintenance logs, replacement intervals, and CO₂ breakthrough events can be recorded within centralized laboratory information management systems (LIMS) using configurable metadata fields aligned with ISO/IEC 17025 clause 7.11. Calibration records for upstream flow meters and conductivity probes remain essential for correlating filter performance with real-time water quality metrics.
Applications
- Guard filtration for UPW storage tanks in semiconductor fab tooling, where sub-ppb TOC and <0.5 µS/cm conductivity are mandatory
- Pharmaceutical manufacturing suites requiring adherence to EU GMP Annex 1 and FDA Aseptic Processing Guidance for water-for-injection (WFI) loop headspace protection
- Centralized research core facilities supplying ultrapure water to ICP-MS, LC-MS/MS, and cell culture incubators
- Calibration laboratories maintaining reference water standards per ISO/IEC 17025 accreditation requirements
- Environmental testing labs performing trace-metal analysis (EPA Method 1638, ISO 17294-2) where atmospheric CO₂ dissolution introduces systematic bias in blank correction
FAQ
What is the recommended replacement interval for the CYTANKPE01 filter cartridge?
Under typical laboratory conditions (average ambient CO₂ ~400 ppm, tank cycling frequency ≤3×/day), the adsorbent life is 6–9 months. Replacement must occur upon visual indicator transition or when system conductivity increases by ≥0.05 µS/cm over baseline.
Can the CYTANKPE01 be sterilized in situ using ozone or hydrogen peroxide vapor?
No. Ozone and H₂O₂ vapors degrade the KOH-activated alumina media and compromise CO₂ adsorption capacity. Only saturated steam sterilization (121 °C, 30 min) is validated.
Is this filter suitable for nitrogen-purged water tanks?
Yes—when used in conjunction with inert gas blanketing, the CYTANKPE01 serves as a fail-safe barrier against air intrusion during pressure transients, extending nitrogen conservation efficiency.
Does the unit meet UL or CE safety certification requirements?
The housing assembly carries CE marking per PED 2014/68/EU Category I pressure equipment directive; no UL listing is applicable due to absence of electrical components.
How is integrity testing performed prior to commissioning?
Integrity is verified via forward-flow bubble point test (≥3.5 bar for 0.2 µm membrane) per ASTM F838-22, followed by CO₂ breakthrough challenge using certified 500 ppm NIST-traceable gas mixture at nominal flow rate.
