Kanomax Model 6715 Air Flow Hood

Overview

The Kanomax Model 6715 Air Flow Hood is a precision-engineered environmental monitoring instrument designed for quantitative measurement of volumetric air flow at HVAC diffusers, grilles, and registers. It operates on the principle of integrated pitot-static pressure differential sensing across a calibrated hood aperture, combined with real-time temperature and relative humidity compensation to deliver traceable, thermodynamically corrected airflow values in m³/h. Unlike single-point anemometers, the 6715 employs a distributed pressure-sampling matrix—optionally configurable with pitot tubes or a multi-point velocity grid—to capture spatial flow uniformity and mitigate turbulence-induced errors. Its architecture conforms to industry-accepted test protocols including ASHRAE Standard 111 (Methods of Testing for Rating Air Terminal Units), ISO 16813 (Indoor Air Quality – General Principles), and ASTM D5482 (Standard Test Method for Determining Airflow Rates of HVAC Diffusers). The device was originally manufactured in Japan and distributed globally through authorized channels; it has since been succeeded by the Model 6720, though the 6715 remains widely deployed in commissioning, retro-commissioning, and routine HVAC performance verification workflows.

Key Features

• Simultaneous measurement of air volume flow (m³/h), face velocity (m/s), differential pressure (Pa), ambient temperature (°C), and relative humidity (%RH)
• Calibrated airflow range of 40–4300 m³/h with total uncertainty of ±3% of reading ±10 m³/h (validated per ISO/IEC 17025-accredited calibration procedures)
• Integrated backpressure compensation algorithm to correct for static pressure buildup during hood placement—critical for low-pressure diffusers and VAV terminal units
• 3.5-inch full-color LCD display with ±30° mechanical tilt adjustment for ergonomic field viewing under varied installation angles
• Onboard data logging capacity of 8,000 measurement records with timestamp, location tag (via optional GPS-enabled mobile app), and audit-ready metadata
• Bluetooth 4.2 wireless interface enabling bidirectional communication with Kanomax’s proprietary iOS/Android application for remote configuration, live streaming, and report generation
• Dual-sensor airflow modes: pitot tube array (0.15–40 m/s) for high-velocity applications and velocity matrix (0.15–15 m/s) for laminar or low-turbulence environments
• Comprehensive environmental compensation: temperature accuracy ±0.5 °C (0–50 °C), humidity accuracy ±3% RH (10–90% RH), differential pressure accuracy ±0.25% of reading ±1 Pa (−2500 to +2500 Pa)

Sample Compatibility & Compliance

The Model 6715 accommodates a wide range of standard and custom hood configurations—including 610 × 610 mm (standard), 610 × 1220 mm, 305 × 1220 mm, 500 × 500 mm, 915 × 915 mm, 915 × 610 mm, 800 × 800 mm, 800 × 1100 mm, 1400 × 800 mm, and 1220 × 1220 mm—ensuring compatibility with ceiling-mounted diffusers, sidewall grilles, perforated panels, and duct take-offs. All interchangeable hoods feature optically transparent acrylic viewing windows for visual alignment verification without compromising structural integrity. The instrument meets electromagnetic compatibility (EMC) requirements per IEC 61326-1 and carries CE marking for use within EU regulatory frameworks. Its measurement methodology supports compliance with HVAC system validation under FDA 21 CFR Part 11 (when used with validated software workflows), ISO 14644-3 cleanroom certification protocols, and GLP/GMP facility qualification documentation standards.

Software & Data Management

Data acquisition and post-processing are supported via Kanomax’s cross-platform mobile application (iOS/Android), which provides real-time telemetry, customizable report templates (PDF/CSV export), and secure cloud synchronization. The application implements role-based user authentication, electronic signature capture, and time-stamped audit trails—features aligned with FDA 21 CFR Part 11 electronic record requirements when deployed in regulated environments. USB and RS-232 interfaces enable direct connection to desktop systems for firmware updates and bulk data transfer. All stored datasets include embedded calibration certificate IDs, sensor drift history, and environmental context tags—facilitating traceability from field measurement to QA/QC review. Firmware versioning and configuration lock-down prevent unauthorized parameter modification during critical testing sequences.

Applications

The Model 6715 is routinely deployed in HVAC commissioning and TAB (Testing, Adjusting, and Balancing) services; hospital ventilation system validation (e.g., ISO 14644-1 cleanrooms, ASHRAE 170 healthcare facilities); pharmaceutical cleanroom airflow mapping; laboratory fume hood face velocity verification (per ANSI/AIHA Z9.5); and energy audit programs requiring accurate supply/exhaust air quantification. Its robust thermal stability and humidity-compensated algorithms make it suitable for field use in data centers, semiconductor fabrication suites, and biotech manufacturing spaces where environmental transients are common. The modular hood design allows rapid adaptation to non-standard register geometries, reducing setup time during large-scale facility surveys.

FAQ

Is the Model 6715 still supported with firmware updates or calibration services?
Yes—though discontinued in favor of the Model 6720, Kanomax continues to provide NIST-traceable calibration, repair, and technical support through its global network of authorized service centers.
Can the 6715 be used for ISO Class 5 cleanroom certification?
Yes, provided the selected hood size matches the diffuser geometry and measurements are performed under ISO 14644-3 Annex B conditions, including background particle monitoring and thermal stability verification.
Does the device comply with FDA 21 CFR Part 11 for electronic records?
The hardware itself is Part 11–capable when paired with validated software configurations; full compliance requires documented SOPs, access controls, and audit trail retention policies implemented at the organizational level.
What is the recommended recalibration interval?
Annual recalibration is advised under normal usage; more frequent intervals (e.g., quarterly) are recommended in high-use or high-humidity environments per ISO/IEC 17025 Clause 7.8.3.
Are replacement hoods and accessories available separately?
Yes—all standard and extended-size hoods, telescoping poles, AC adapters, Bluetooth printers, and pitot tube assemblies are available as genuine Kanomax spare parts with documented metrological traceability.
