  • Description

    Precision Fume Hood Testing for ANSI/ASHRAE 110 Compliance

    The Kanomax Tracer Gas Diffusor Kit (Dif‑Kit) is a professional solution for accurate, repeatable fume hood performance testing. Developed exclusively for ANSI/ASHRAE 110 tracer gas testing, it empowers lab technicians, safety engineers and HVAC specialists to assess containment performance with high confidence and precision.

    Built to withstand the stringent requirements of modern laboratory settings, this complete tracer gas system delivers dependable airflow diagnostics while supporting safer, more streamlined testing procedures.

    Designed for ANSI/ASHRAE 110 Tracer Gas Testing

    The Dif‑Kit is purpose-engineered for ANSI/ASHRAE 110‑1995, the industry standard for laboratory fume hood containment evaluation. It enables controlled tracer gas discharge and precise flow regulation, simulating contaminant movement inside the hood accurately.

    The diffuser is manufactured strictly in accordance with Standard Drawing #110‑83M, ensuring stable, standard-compliant test conditions.

    Accurate and Controlled Gas Diffusion

    Its built-in critical orifice maintains a constant tracer gas flow of 4 L/min, supporting consistent, reproducible test results across repeated measurements.

    Complete Tracer Gas Testing Solution

    The Dif‑Kit contains all core hardware required for professional testing:

    • Dual-stage specialty gas regulator
    • Calibrated flow meter (150 mm / 200 psi glass tube)
    • Pressure gauge (0–60 psi)

    These components work in tandem to achieve precise gas regulation and measurement.

    Flexible Tracer Gas Options

    To suit environmental and regulatory requirements, the system is compatible with multiple tracer gases:

    • SF₆ (Sulfur Hexafluoride)
    • NO₂ (Nitrogen Dioxide)
    • FM‑200 (HFC‑227)

    This flexibility lets facilities select low‑GWP alternatives without compromising test accuracy.

    Enhanced Airflow Visualization

    An optional fog machine delivers visual verification of airflow patterns and containment. With particle sizes from 0.25 to 60 microns, users can clearly observe airflow behaviour and spot leaks or turbulence.

    Integrated Face Velocity Testing

    The Dif‑Kit can be paired with an optional thermal anemometer for precise face velocity readings, supporting a full‑scope fume hood performance assessment.
