10 steps to close the gap in the containment
Step 3: Avoidance of cross-contamination.
Engineering of air management solutions, so that no cross-contamination of products can occur.

When engineering the project, great care must be taken to ensure that the containment is not broken at any time and any place.

  • The dust collection
    must be designed, so that no dust can escape into the room.
  • The Air Management
    must be designed in a way, that the collected dust is directed into the filter system and no dust deposits can occur.

If the dust collection and air management are correctly designed, no cross-contamination of products can occur.

  1. Grading of standardized self-cleaning HEPA filter units according to OEB requirements OEB 1-6.
  2. Selection of equivalent self-cleaning HEPA filter systems, which comply with the respective production machine(s), so that both can be validated at the same OEB level.
  3. Avoidance of cross-contamination.
    Engineering of air management solutions, so that no cross-contamination of products can occur.
  4. Developing filtration islands
    for 1-5 production machines only.
  5. Protection of the environment.
    Guaranteed filter efficiency H14 EN 1822 at any time.
  6. Protection of the operator during dust recovery
    OEB 1-6
  7. Protection of the operator during HEPA filter change
    OEB 1-6
  8. Fully automated control technology
    to avoid false handling of the system by the operator at any time.
  9. Explosion prevention
    to avoid any kind of explosion within the filter system and thus protect the operator and the environment, as well as prevent cross-contamination.
  10. Validation of the filter system. The self-cleaning HEPA filter system becomes a fully adequate production machine.
