Kanomax Model 6710 Air Flow Hood for HVAC Commissioning in Pharmaceutical Cleanrooms

Overview

The Kanomax Model 6710 Air Flow Hood is a precision-engineered instrument designed specifically for HVAC commissioning, qualification, and routine monitoring in regulated pharmaceutical environments—including ISO Class 5–8 cleanrooms, aseptic processing suites, and controlled laboratory spaces. It operates on the principle of volumetric flow measurement via calibrated hood geometry and integrated thermal anemometry, with simultaneous real-time acquisition of air volume, dry-bulb temperature, and relative humidity. Unlike conventional anemometers or pitot-static systems, the 6710 employs a pressure-compensated hood design that corrects for system backpressure—critical when measuring airflow at terminal devices such as HEPA-filtered supply diffusers, laminar flow hoods, and biological safety cabinets where static pressure variations directly impact volumetric accuracy. Its measurement architecture complies with fundamental requirements outlined in ISO 14644-3 (Cleanroom Testing), EU GMP Annex 1 (2022), and IEST-RP-CC034.2 (Testing Cleanrooms), supporting objective evidence generation for Design Qualification (DQ), Installation Qualification (IQ), Operational Qualification (OQ), and Performance Qualification (PQ) protocols.

Key Features

• Simultaneous three-parameter measurement: air volume (m³/h), temperature (°C), and relative humidity (%RH) — all captured and logged per measurement event
• Backpressure compensation algorithm automatically adjusts flow calculation based on differential pressure across the hood face, minimizing systematic error in high-resistance duct terminations
• 3.5-inch full-color LCD with automatic 30° tilt adjustment for ergonomic viewing under ceiling-mounted or recessed diffuser conditions
• High-resolution flow measurement down to 1 m³/h with extended linear range from 40 to 4300 m³/h — suitable for both low-flow isolators and high-capacity supply registers
• Integrated environmental sensing: temperature accuracy ±0.5 °C (0–60 °C); RH accuracy ±3% RH within 10–90% RH range, traceable to NIST-traceable calibration standards
• Robust data management: internal storage capacity of 3,000 measurement records with timestamp, location tag, and operator ID fields; supports USB mass-storage mode for direct file transfer to Windows-based analysis software
• Dual power options: standard operation on four AA alkaline cells (typical 9-hour runtime) or continuous use via external DC 5 V adapter — essential for extended commissioning shifts

Sample Compatibility & Compliance

The Model 6710 accommodates a wide range of terminal airflow devices through its modular hood system. Standard 610 × 610 mm hood meets common diffuser footprints in pharmaceutical facilities; optional sizes—including 305 × 1220 mm (for linear slot diffusers), 915 × 915 mm (large-area supply grilles), and 1220 × 1220 mm (high-volume AHU outlets)—enable full-spectrum coverage without compromising measurement integrity. All hoods feature optically transparent polycarbonate windows for visual alignment verification and built-in K-factor registration for rapid field recalibration. The instrument’s metrological performance aligns with ASTM D1898 (Standard Practice for Airflow Measurement Using Thermal Anemometers) and supports audit readiness for FDA 21 CFR Part 11-compliant data workflows when used with Kanomax’s validated PC software suite (v3.2+), which provides electronic signature capability, audit trail logging, and user access controls.

Software & Data Management

Kanomax provides proprietary Windows-compatible software (included) for post-acquisition analysis, report generation, and database integration. The application supports batch export to CSV, Excel, and PDF formats with customizable templates aligned to ISO 14644-3 reporting conventions. Each stored record includes full metadata: date/time stamp, ambient temperature/RH, measured flow, backpressure delta, battery level, and user-defined test point ID. Raw data files are digitally signed and tamper-evident, satisfying ALCOA+ principles (Attributable, Legible, Contemporaneous, Original, Accurate, Complete, Consistent, Enduring, Available). Optional RS-232 serial output enables direct connection to legacy building management systems (BMS) or PLC-based logging infrastructure. Firmware updates are delivered via USB and include version-controlled release notes compliant with ICH Q9 risk management expectations.

Applications

• Pharmaceutical HVAC commissioning: balanced airflow verification across supply, return, and exhaust terminals per EU GMP Annex 1 §4.37–4.42
• Cleanroom classification surveys: ISO 14644-1 particle count correlation with volumetric air change rate validation
• Aseptic processing support: laminar airflow uniformity testing at critical work surfaces (e.g., filling lines, isolator glove ports)
• HEPA filter leak testing pre- and post-integrity scan: quantitative flow verification prior to DOP/PAO challenge
• Facility lifecycle monitoring: trending of airflow degradation over time to inform preventive maintenance scheduling
• Regulatory inspection readiness: generation of auditable, timestamped datasets for FDA, EMA, PMDA, or WHO pre-approval inspections

FAQ

Does the Model 6710 meet ISO 14644-3 requirements for cleanroom airflow testing?
Yes — its backpressure compensation, resolution, and documented uncertainty budget satisfy Clause 6.2.2 (Air Volume Flow Rate Measurement) and Annex B (Instrument Specifications) of ISO 14644-3:2019.
Can the device be used in high-humidity environments such as wet labs or sterilization areas?
Yes — it operates continuously at 0–100% RH with specified accuracy maintained between 10–90% RH; condensation-resistant housing and sealed sensor ports prevent moisture ingress during short-term exposure.
Is firmware validation documentation available for GxP environments?
Yes — Kanomax provides a Firmware Validation Package (FVP) upon request, including installation qualification (IQ) scripts, operational qualification (OQ) test cases, and traceability matrices aligned with ASTM E2500 and GAMP 5.
How is calibration traceability established for field use?
Each unit ships with a certificate of calibration traceable to JCSS (Japan Calibration Service System), equivalent to ISO/IEC 17025; annual recalibration is recommended and supported by Kanomax-certified service centers globally.
Can multiple hood sizes be registered and recalled within the same instrument?
Yes — up to eight custom hood configurations (including K-factors, dimensions, and serial identifiers) can be stored internally and selected per measurement session via the menu interface.
