There was a need to ensure an ultra-clean, one-directional flow for the bottling of vaccines.
In the pharmaceutical field, the A/B class is the most constraining and most difficult to obtain.
The objective is to ensure a one-directional flow and to respect an air speed limit between 0.4 and 0.45 m/s under the whole flow surface.
Solution implemented by Clauger:
The class A(B) is obtained due to ventilation units and filtration (FFU) ensuring a minimal brewing rate of 400 vol/hours.
Numerous parameters should be controlled
Fundamental parameters to control for:
