Kanomax 6720-DP Grid Air Flow Hood

Overview

The Kanomax 6720-DP Grid Air Flow Hood is a precision-engineered, multi-parameter environmental measurement instrument designed for HVAC commissioning, cleanroom qualification, and pharmaceutical facility validation. It integrates a calibrated grid-based airflow sensor array with an integrated pitot-static probe and differential pressure transducer to simultaneously quantify volumetric airflow (m³/h), face velocity (m/s), and static pressure differentials (Pa) across grilles, diffusers, and terminal HEPA filters. Unlike single-point anemometers, the 6720-DP Grid employs a 16-point spatial averaging matrix—mounted on a rigid, lightweight hood frame—to capture representative cross-sectional airflow profiles in accordance with ISO 14644-3, ISO 14644-4, and EU GMP Annex 1 requirements. Its dual-sensor architecture enables traceable, repeatable measurements under dynamic duct conditions while maintaining compliance with ASHRAE Standard 111 and ANSI/ASHRAE Guideline 12.

Key Features

• Simultaneous real-time measurement of air volume (40–4300 m³/h), face velocity (0.15–15 m/s via grid; up to 40 m/s via optional pitot tube), and differential pressure (±2500 Pa)
• 4.3-inch high-resolution capacitive touchscreen with intuitive icon-driven UI, supporting multi-language operation (English, Japanese, Chinese, Korean)
• On-board K-factor adjustment for custom calibration against reference standards or facility-specific duct geometries
• Bluetooth 4.2 wireless interface enabling bidirectional communication with the Kanomax Smart mobile application (iOS/Android) for remote configuration, live monitoring, and report generation
• Dual storage architecture: 8,000 measurement records retained internally; up to 10,000 stored via app—each record timestamped, geotagged (optional), and annotated with operator ID and test location
• Integrated power management: auto-sleep mode after 5 minutes of inactivity; battery level indicator; DC 5 V external power option for extended benchtop use

Sample Compatibility & Compliance

The 6720-DP Grid accommodates standard rectangular and square supply/exhaust grilles ranging from 300 × 300 mm to 1200 × 1200 mm. Its modular hood design allows rapid adaptation to non-standard openings using optional extension frames and sealing gaskets. All airflow calculations comply with ISO 14644-3 Annex B (grid-based averaging method) and are traceable to NIST-traceable calibration certificates (available upon request). The instrument meets IEC 61000-4-2 (ESD immunity), IEC 61000-4-3 (radiated RF immunity), and RoHS 2011/65/EU directives. For regulated environments, audit trails—including user login, parameter changes, and data export events—are logged in accordance with FDA 21 CFR Part 11 principles when used with Kanomax’s validated software suite.

Software & Data Management

The Kanomax Smart App provides secure, encrypted synchronization of field measurements and supports customizable report templates compliant with ISO/IEC 17025 documentation requirements. Export formats include CSV (for LIMS integration), PDF (with embedded digital signature), and XML (for enterprise EAM systems). USB mass-storage mode enables direct file transfer to Windows/Linux workstations without proprietary drivers. Firmware updates are delivered over-the-air via Bluetooth or manually loaded via microSD card. All stored data includes metadata: date/time stamp, ambient temperature/RH, battery voltage, sensor serial numbers, and operator-defined test IDs—ensuring full data integrity for GLP/GMP audits.

Applications

• HVAC system balancing and TAB (Testing, Adjusting, Balancing) per ASHRAE Guideline 1
• Cleanroom airflow uniformity verification (ISO Class 5–8), including unidirectional flow visualization support
• Pharmaceutical isolator and RABS airflow characterization per EU GMP Annex 1 Section 4.39
• HEPA filter leak testing pre- and post-integrity scan (used in conjunction with particle counters)
• Exhaust hood face velocity validation in laboratories (ANSI Z9.5 compliance)
• Energy efficiency assessments per ASHRAE Standard 90.1 and LEED EA Credit 1

FAQ

Does the 6720-DP Grid require annual recalibration?
Yes. Kanomax recommends annual factory recalibration against NIST-traceable standards to maintain stated accuracy specifications and regulatory compliance.
Can the device measure airflow in recirculating or turbulent ducts?
It is optimized for supply/exhaust terminals with laminar or transitional flow profiles. For highly turbulent or recirculating zones, use the optional pitot tube with traverse method per ISO 14644-3 Annex C.
Is the Bluetooth connection secure for use in controlled facilities?
Bluetooth pairing uses AES-128 encryption; no persistent network exposure occurs. Data transmission is point-to-point only and does not broadcast SSIDs or establish ad-hoc networks.
What validation documentation is provided for GxP environments?
A complete IQ/OQ protocol package—including installation checklist, operational test scripts, and blank execution records—is available upon request. Full 21 CFR Part 11 compliance requires use of Kanomax Smart App v3.2+ with enabled electronic signature modules.
How is K-factor determined for non-standard grille configurations?
K-factor is derived empirically during initial commissioning by comparing 6720-DP Grid readings against a reference flow hood or calibrated venturi meter at identical operating conditions; the value is then entered into the device’s calibration menu.
