Kanomax Model 6710 Air Flow Hood for HVAC Commissioning and Balancing

Overview

The Kanomax Model 6710 Air Flow Hood is a precision-engineered instrument designed specifically for HVAC system commissioning, balancing, and routine air distribution verification in commercial and institutional buildings. It operates on the principle of volumetric flow measurement via pressure differential across a calibrated grid—combined with real-time temperature and relative humidity sensing—to deliver simultaneous, traceable airflow (m³/h), dry-bulb temperature (°C), and ambient RH (%) readings at supply/return grilles and diffusers. Unlike handheld anemometers or pitot-static systems requiring multiple point measurements and spatial averaging, the 6710 employs a single-pass, full-face capture method that eliminates operator-induced variability and ensures high reproducibility per ANSI/ASHRAE Standard 111 and ISO 16813-compliant testing protocols. Its robust aluminum-magnesium alloy housing, ergonomic rotating display, and built-in backpressure compensation algorithm enable stable measurements even under variable static pressure conditions typical of low-velocity duct terminations.

Key Features

• Simultaneous three-parameter measurement: volumetric airflow (40–4300 m³/h), temperature (0–60 °C, ±0.5 °C), and relative humidity (0–100% RH, ±3% RH within 10–90% RH range)
• 3.5-inch full-color LCD with automatic 30° tilt adjustment for optimal viewing angle—eliminates neck strain during ceiling-mounted or recessed grille testing
• Integrated backpressure compensation circuitry corrects for flow resistance induced by hood geometry and upstream duct constraints, maintaining accuracy across diverse installation configurations
• Translucent front viewing window enables visual confirmation of grille alignment and airflow uniformity without removing the hood from the test surface
• Onboard data logging stores up to 3,000 complete measurement records with timestamps, location tags, and environmental metadata—supporting ASHRAE Guideline 1-2021 documentation requirements
• Dual-power architecture: 4 × AA alkaline batteries (typical 9-hour runtime) or external DC 5 V input—enabling uninterrupted field operation during extended balancing sessions
• Standard 610 × 610 mm hood included; 9 additional optional hood sizes available—including oversized configurations (e.g., 1220 × 1220 mm) for large VAV boxes and air handling unit outlets

Sample Compatibility & Compliance

The Model 6710 is validated for use with standard square, rectangular, and round supply diffusers, return grilles, and exhaust registers commonly found in office buildings, hospitals, laboratories, and cleanrooms. Its modular hood system accommodates irregular geometries through interchangeable panels and optional telescoping extension rods (sold separately). The instrument meets electromagnetic compatibility (EMC) requirements per IEC 61326-1:2020 and carries CE marking for conformity with EU Directive 2014/30/EU (EMC) and 2014/35/EU (LVD). While not certified as intrinsically safe, it is rated for non-hazardous environments per IP42 ingress protection. Measurement uncertainty budgets align with ISO/IEC 17025:2017 calibration traceability frameworks when used with NIST-traceable reference standards.

Software & Data Management

Data export is supported via USB 2.0 interface to Windows-based Kanomax AirFlow Manager software (v3.x), which provides automated report generation compliant with LEED EQc1, CxP, and TAB (Testing, Adjusting, and Balancing) documentation templates. The software enables batch calibration coefficient updates, statistical analysis of multi-point surveys, and PDF export with embedded digital signatures. All stored records include audit trail metadata (operator ID, timestamp, GPS coordinates if enabled via connected mobile device, and environmental conditions)—supporting GLP-aligned record retention practices. USB transfer preserves native CSV structure for direct import into BMS validation databases or Excel-based QA workflows.

Applications

• HVAC system commissioning per ASHRAE Guideline 0-2019 and NEBB Procedural Standards
• Annual air balance verification in healthcare facilities per FGI Guidelines and Joint Commission EC.02.05.01
• Room pressurization validation in pharmaceutical cleanrooms (ISO 14644-3) and biosafety labs (BSL-2/3)
• Energy audit baseline measurements for retro-commissioning projects (ASHRAE RP-1081)
• Post-construction duct leakage verification using grille-level flow summation techniques
• Educational laboratory instruction in building science and mechanical engineering curricula

FAQ

Does the Model 6710 require annual recalibration?
Yes—Kanomax recommends annual factory recalibration against NIST-traceable airflow standards to maintain stated accuracy specifications and support ISO/IEC 17025 compliance.
Can the 6710 measure airflow in exhaust hoods or fume cabinets?
It is suitable for low-velocity exhaust applications where face velocity remains within the 0.15–15 m/s range and static pressure does not exceed ±250 Pa; however, dedicated fume hood testers with higher differential pressure ranges are recommended for safety-critical containment verification.
Is Bluetooth connectivity available on the 6710?
No—Bluetooth is exclusive to the Model 6720. The 6710 supports wired USB data transfer and RS-232 printer output only.
What is the maximum allowable static pressure during measurement?
The unit maintains specified accuracy up to ±125 Pa backpressure; beyond this, performance degradation may occur unless compensated using the built-in backpressure correction function.
Are firmware updates provided free of charge?
Yes—Kanomax publishes verified firmware revisions on its global support portal; updates are installed via USB and preserve all user-configured settings and stored data.
