KANOMAX 6750 Air Flow Hood

Overview

The KANOMAX 6750 Air Flow Hood is a precision-engineered, handheld volumetric airflow measurement instrument designed for HVAC commissioning, facility validation, and indoor air quality (IAQ) assessments in cleanrooms, laboratories, hospitals, and pharmaceutical production environments. Utilizing a calibrated multi-venturi array integrated into a rigid, ergonomic hood frame, the device measures total volumetric airflow (m³/h or CFM) directly at diffusers, grilles, and registers without requiring duct access or upstream velocity profiling. Its principle of operation relies on differential pressure sensing across an array of precision-machined venturis—each individually characterized—to deliver high linearity and low turbulence-induced error across the full dynamic range. Unlike single-point anemometers or thermal probes, the 6750 captures spatially averaged flow profiles in real time, minimizing operator-dependent variability and enabling repeatable, audit-ready measurements under ISO 14644-3, EU GMP Annex 1, and ASHRAE Standard 111 test protocols.

Key Features

• Ergonomic, one-person operable design with lightweight aluminum alloy frame and balanced center-of-gravity for stable positioning over ceiling-mounted or wall-mounted air terminals
• High-resolution 4.3-inch full-color TFT LCD display with intuitive icon-based UI, real-time trend graphing, and transparent acrylic viewing window for simultaneous visual alignment and digital readout
• Integrated Bluetooth 4.2 (BLE) module enabling secure, low-latency wireless communication with the KANOMAX AirFlow Manager™ desktop and mobile applications—no cables or dongles required
• Rechargeable lithium-ion battery supporting ≥8 hours of continuous measurement cycles, with USB-C fast charging and battery-level indicator
• Automatic zero calibration and self-diagnostic routines prior to each measurement session, ensuring metrological traceability and reducing pre-test setup time
• IP54-rated enclosure for resistance against dust ingress and incidental water splashing during field use

Sample Compatibility & Compliance

The KANOMAX 6750 is validated for use with standard square and rectangular supply/exhaust diffusers ranging from 300 × 300 mm to 1,200 × 1,200 mm (custom adapter kits available). It accommodates both laminar and turbulent flow regimes typical of VAV boxes, HEPA-filtered terminals, and return air grilles. All factory calibrations are performed per JIS B 8623:2019 (Methods for Testing Performance of Air Flow Measuring Instruments) and are traceable to NMIJ/AIST (National Metrology Institute of Japan) standards. The instrument meets CE marking requirements under the EMC Directive 2014/30/EU and RoHS 2011/65/EU. For regulated environments, measurement data logs generated via the AirFlow Manager software support 21 CFR Part 11-compliant electronic records when deployed with user authentication, audit trail, and electronic signature modules enabled.

Software & Data Management

The companion AirFlow Manager™ software (Windows/macOS/iOS/Android) provides comprehensive post-processing capabilities including automatic report generation (PDF/CSV), multi-point comparative analysis, deviation mapping against setpoints, and export to Excel-compatible formats. Each measurement record embeds metadata such as timestamp, GPS coordinates (mobile), ambient temperature/humidity (via optional external sensor), operator ID, and hood serial number. Audit trails log all user actions—including data edits, deletions, and calibration events—with immutable timestamps. Data encryption (AES-256) and role-based access control ensure integrity in GLP/GMP-regulated workflows.

Applications

• HVAC system balancing and TAB (Testing, Adjusting, Balancing) in commercial and healthcare facilities
• Cleanroom certification per ISO 14644-3 and FDA Guidance for Industry: Sterile Drug Products Produced by Aseptic Processing
• Pharmaceutical facility qualification (IQ/OQ/PQ) of air handling units and laminar flow hoods
• Energy auditing and retrocommissioning studies targeting ventilation efficiency optimization
• Academic and industrial research involving airflow distribution modeling and CFD validation
• Occupational health & safety assessments for local exhaust ventilation (LEV) systems per OSHA Technical Manual Section III: Chapter 5

FAQ

What is the recommended recalibration interval for the KANOMAX 6750?
KANOMAX recommends annual factory recalibration or after any impact event that may affect sensor alignment. Field verification using a certified reference flow standard is advised before critical validation runs.
Can the 6750 measure negative (exhaust) airflow accurately?
Yes—the device measures bidirectional volumetric flow with equal accuracy across its full ±8–600 m³/h range, making it suitable for both supply and exhaust terminal testing.
Is the Bluetooth connection secure enough for regulated environments?
Yes—Bluetooth pairing requires manual initiation and uses encrypted session keys. When used with AirFlow Manager’s Part 11 mode, all transmitted data undergoes end-to-end encryption and is logged within the system’s immutable audit trail.
Does the instrument comply with ISO 17025 requirements for accredited labs?
While the 6750 itself is not a certified reference standard, its calibration certificate includes uncertainty budgets compliant with ISO/IEC 17025:2017 Annex A. Accredited laboratories may incorporate it into their scope of accreditation subject to internal validation per Clause 7.7.
