10 steps to close the gap in the containment
Step 1: Grading of standardized self-cleaning HEPA filter units

according to OEB requirements OEB 1-6.

  • The unit series MMS 10/2 – 8.2
    is designed for extremely high toxic level OEB 6, with a capacity of 
1.000 – max. 12.000 m³ / h each.
  • The unit series MMS 20/2 – 8.2
is designed for toxic and highly toxic levels OEB 4-5, with a capacity of 
2.500 – 24.000 m/³ / h each.
  • The unit series MMS 24/2 – 8.2
    is designed for low toxic and medium toxic levels OEB 2-3, with a capacity of 
3.000 – 29.000 m/³ / h each.
  • The unit series MMS 28/2 – 8.2
    is designed for non toxic level OEB 1, with a capacity of 
3.500 – 33.000 m/³ / h each.

Basically, all units are designed with bag in bag out systems for filter change and dust recovery, so that the system can be serviced from outside without contamination.

Furthermore, the control technology is designed fully automatically, so that no error by false handling of an operator can occur.

Due to that the self-cleaning HEPA filter system can be validated together with the production machine(s) at the same OEB level in order to close the gap in containment.

  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.
