10 steps to close the gap in the containment
Step 4: Developing filtration islands
for 1-5 production machines only

Central dust extraction systems

Central dust extraction systems , which are today still mostly applied in Chemical and Pharmaceutical industries are in this field of industry completely unsuitable. 
The filter units are by far too far away from the production machines, so that very long pipes are required, which can never be cleaned as required.

The air velocities in the pipes cannot be maintained in such a way that no dust deposits occur in the pipes. Dust deposits in the pipe system mean that the necessary pressures and air volumes can no longer be maintained within the respective production room, resulting that containment is broken.

Filtration islands

By engineering filtration islands, the self-cleaning HEPA filter systems can be installed as close as possible to production machines, so that the ducts are as short as possible, can be cleaned, air volumes and pressures can be maintained, and thus no contamination of the operator or cross-contamination can occur.

Due to the fact that self-cleaning HEPA filter units are designed in a way, so that no dust explosion can occur within, they are highly suitable to be installed inside the building close to production sites.

  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.
