Flow visualizations show the movement patterns of air in a room, allowing analysis and forecasting. They are therefore central requirements of the
guidelines as well as
and
High-quality flow visualizations are also becoming increasingly important for FDA inspections – a requirement that
fully meets.
Finding particle entries
Of course, we also take on this task following modification measures to your
or when fixtures and machines have been adapted to the manufacturing processes of a new product. Also,
can help track down unexplained intrusion of particles.
CAT Group’s experts visualize the flow pattern on site using specially developed, state-of-the-art
and based on a script defined together with the customer. The air stream impinged with residue-free fog is recorded with at least one high-resolution camera, which also detects the thinnest swaths and the finest turbulences.

CLEANROOM KNOWLEDGE
Quick test: Ask someone you know if they know what a cleanroom is. Most people will probably say something along the lines of “medicine” and “clean.” How cool would it be if you could just rattle off a smooth explanation right off the top of your head!

The survival guide nobody gives you before your first shift
Airflow visualization - often referred to as a smoke study - uses visible smoke to illustrate the movement of air within a cleanroom. This allows one to observe how the air flows and whether undesirable turbulence or potential contamination risks arise. As such, these studies are key requirements of the EU GMP guidelines as well as DIN EN ISO 14644 and VDI 2083.
Flow visualization can be just as useful during the commissioning and qualification of a cleanroom as it is after renovations, system modifications, or the installation of new machinery. It can also assist in identifying the causes of unexplained particle ingress.
First, the situations and process sequences to be examined are defined. Next, a suitable smoke plume is generated, and its movement is documented using cameras so that the flow behavior can then be analyzed.
Yes. The visualization can be documented and evaluated according to the project requirements. We coordinate the required scope of documentation with the client in advance.
Yes. Depending on the task at hand, different operating conditions can be examined. Visualization under conditions that closely resemble the eventual production process is often particularly informative.
If anomalies are detected, targeted optimization measures can be derived from them - for example, regarding airflow, equipment, process sequences, or technical components.
The CAT Group not only has extensive experience in the field of flow visualization - it has also developed and launched the CAT Pure Fog, a state-of-the-art fog generator.
