Measuring laminar flow in paint booths, clean rooms, semiconductor production

Flow velocity for process regulation for paint booth, clean rooms, semiconductor and filling and packaging applications.

Application

These low in turbulence laminar flows are necessary to ensure the required air exchange in clean rooms or glove boxes. It’s important that the laminar flow doesn’t cause a stir of small dust particles. Therefore flow velocity in process integrated air conditioners has to be quite low. Laminar flow is also required in other applications such as paint booths or ventilation in buildings. It has been relevant in the area of workplace ventilation and safety long before Corona. Clean rooms are important in medical-pharmaceutical and biotechnological fields to create controllable and therefore replicable environmental conditions. Optimally regulated air conditioners play a significant role in surgery rooms. Other areas that require replicable clean room conditions are electronics and wafer productions as well as many laboratories in basic research and material research. Special applications in the packaging industry also require clean room conditions that are unimaginable without the right sensor technology to monitor and regulate the installed air conditioners.
