Smoke studies make it possible to make visible the airflows present in a cleanroom. This airflow is a factor that can influence product quality. In cleanrooms, areas where turbulence must be particularly low are a source of concern. All installations (machines, furniture) constantly cause flow deviations or uncontrolled turbulence. To visualize these, we use a distilled water-based ultrasonic fogger (WFI) that generates a high-density, non-toxic fog. This fog is then injected into the areas to be studied. Using various visual aids, we can analyze the data and visualize them in a photo/video montage. All results are documented in a very detailed report.
The fundamental objective of smoke studies is to make cleanroom airflows visible. The low-turbulence range is of particular interest. In the low-turbulence range, structures such as machines, etc., frequently lead to flow deflection and unintentional turbulence.
Smoke studies use a fog generator, which produces a thick, saturated fog free of all toxins. This fog is applied to the air inlet under examination, and the resulting flow pattern is recorded using digital video or a camera. The film material is then converted into a video and supplemented with a detailed report.
