Airflow smoke pattern tests are used to visualize airflow in various environments, such as cleanrooms, HVAC systems, pharmaceutical manufacturing, and data centers. These tests help identify airflow patterns, turbulence, dead zones, and potential contamination risks.
Common Methods of Airflow Smoke Pattern Testing
Smoke Tubes – Contain chemical reagents that generate visible smoke when squeezed.
Fog Machines – Produce a controlled fog that moves with the airflow.
Dry Ice (CO₂ Fogging) – Creates a low-lying fog to visualize airflow.
Incense Sticks or Smoke Wands – Small, localized airflow visualization.
Laser-Illuminated Smoke – Enhances visibility in low-light environments.
Applications
Cleanrooms & Pharmaceutical Facilities – Ensure laminar airflow and minimize contamination.
HVAC Systems – Identify leaks, inefficiencies, and stagnant airflow areas.
Data Centers – Optimize cooling airflow around server racks.
Industrial & Laboratory Environments – Maintain safe working conditions and ventilation efficiency.
Best Practices
Use a neutral, non-contaminating smoke source.
Conduct tests under normal operating conditions.
Record and analyze results using video or thermal imaging.
Ensure proper ventilation to clear residual smoke.
