Precision Fume Hood Testing for ANSI/ASHRAE 110 Compliance
The Kanomax Tracer Gas Diffusor Kit (Dif-Kit) is a professional-grade solution designed for accurate and repeatable fume hood performance testing. Engineered specifically for ANSI/ASHRAE 110 tracer gas testing, the Dif-Kit enables laboratory professionals, safety engineers, and HVAC specialists to evaluate containment performance with confidence and precision.
Built to meet the rigorous demands of modern laboratory environments, this comprehensive tracer gas system delivers reliable airflow diagnostics while supporting safer, more efficient testing workflows.
Designed for ANSI/ASHRAE 110 Tracer Gas Testing
The Dif-Kit is purpose-built to support the ANSI/ASHRAE 110-1995 standard, the industry benchmark for evaluating laboratory fume hood containment performance. By providing controlled tracer gas release and precise flow regulation, the system allows for accurate simulation of contaminant behavior within the hood environment.
The diffuser itself is manufactured to the exact design specifications of Standard Drawing #110-83M, ensuring consistent and compliant test conditions.
Accurate and Controlled Gas Diffusion
The integrated critical orifice design ensures a consistent tracer gas flow rate of 4 liters per minute, enabling repeatable and reliable test results across multiple evaluations.
Complete Tracer Gas Testing Solution
The Dif-Kit includes essential hardware components required for professional testing, such as:
- Dual-stage specialty gas regulator
- Calibrated flow meter (150 mm / 200 psi glass tube)
- Pressure gauge (0–60 psi)
These components work together to deliver precise gas control and measurement.
Flexible Tracer Gas Options
To accommodate environmental and regulatory considerations, the system supports multiple tracer gases, including:
- SF₆ (Sulfur Hexafluoride)
- NO₂ (Nitrogen Dioxide)
- FM-200 (HFC-227)
This flexibility allows facilities to choose alternatives that minimize greenhouse gas impact while maintaining test accuracy.
Enhanced Airflow Visualization
An optional commercial fog machine provides visual confirmation of airflow patterns and containment performance. With particle sizes ranging from 0.25 to 60 microns, users can clearly observe airflow behavior and identify potential leakage or turbulence.
Integrated Face Velocity Testing
The Dif-Kit can be paired with an optional thermal anemometer for precise face velocity measurements, enabling a more comprehensive evaluation of fume hood performance.
