Tracking down particles
In the field of cleanroom acceptance measurements, flow visualizations are becoming increasingly important: Not only are they a central requirement of the VDI and ISO guidelines, but also in inspections by the FDA, more and more emphasis is put on the performance of flow visualizations and above all to their quality – a quality you are entitled expect from us.
Flow visualizations show the movement patterns of the air in the room which allows areas with little or insufficient air exchange to be identified, i.e. areas where impurities such as particles and germs can collect. Before commissioning a clean room, such visualizations are often indispensable.
This also applies to the same extent after conversion measures in the clean room or if fixtures and machines have been adapted to the manufacturing processes of a new product. Then it has to be proven again that the flow pattern still meets the requirements and that the structural change does not negatively influence the airflow trajectory. Flow visualizations can also help to track down unexplained particle entries.
We at CAT Clean Air Technology GmbH make the flow pattern in your production facilities visible for you with fog generators from our own production. They work without leaving any residue – either on DI water or on nitrogen basis – and thus offer, unlike conventional foggers, no breeding ground for possible germs. Everything you need to protect your clean room from possible contamination.
The nebulized air flow is recorded with at least one high-resolution camera which also detects the thinnest swaths and the finest turbulences. In this way, we comprehensively document the current situation in order to analyze the results obtained and identify sustainable optimization opportunities.
