Modern Cleanroom Technology


This conference will present state-of-the-art examples of cleanrooms, cleanroom technology and entire facilities. Requirements by the revised Annex 1 are thereby highlighted.



Knowing the regulatory requirements on rooms and HVAC systems is an absolute prerequisite for all further steps like design, qualification and operation of clean rooms.
It is therefore essential to be aware of all restrictions and relations between material and personnel flows before starting with the building of clean rooms for pharmaceutical manufacturing. This is the starting point for the zone concepts and the required airlocks.
Depending on the product or project requirements, other points must also be considered, such as the filter technology, the design of the HVAC system and possibly tightness tests.
The clean room itself consists of floor, wall and ceiling systems suitable for the intended use. Now, which systems are suitable for which clean zones or processes? How can an isolator be integrated in the concept? And what is the impact of the revised Annex 1 on clean rooms and HVAC systems?

Target Audience

This conference is directed at specialists in pharmaceutical engineering departments and production, involved in the planning, qualification or operation of pharmaceutical manufacturing environments. Engineering companies and GMP-planners are also the target group of this conference.

HVAC-System Design for a High Potent Facility
Nikolaus Ferstl, University Hospital of Regensburg

  • Cleanroom Classification & Pressure Zones
  • HVAC Zoning and Segregation
  • HVAC Supply Concepts
  • Design Parameters
  • Filtration Systems
  • Tightness and tightness testing

Setup of a Contamination Control Strategy Using the HACCP Methodology
Ruben van der Galiën, GE HealthCare

  • Application of the Hazard Analysis Critical Control Point (HACCP) methodology to monitor all Critical Control Points (CCPs) related to various sources of contamination
  • Description of the way how to set up a CCS within a pharmaceutical sterile and aseptic manufacturing facility applying the HACCP methodology
  • Use of the HACCP methodology enables a company to include proactive data within the CCS, making use of all identified sources of contamination, associated hazards, and/or control measures and CCPs
  • The constructed CCS allows the manufacturer to identify whether all included sources of contamination are under control and, if not, which mitigatory actions need to be performed

Airflow Visualization within the critical Zone of Cleanrooms and Barrier Systems
Luigi Scaffidi, Boehringer Ingelheim Pharma

  • Regulatory requirements
  • Prerequisites, techniques, operating states, relevant process steps, life cycle
  • Selection of tracer particles (What's the deal with neutral buoyancy?)
  • Case studies

  • ISO 14644-1: Examples from Space, MedTec, semiconductor industries
  • Visualization setup regarding airflow studies for open vials
  • Particle fallout risk assessment using silicon wafers as witness samples: Case scenarios:
    • Displacement pipetting robot with vertical airflow
    • Isolator with horizontal airflow

Assessment of microbial Contamination in a sterile Production Environment
Doris Laçej, Profarma

In practice, environmental monitoring has shown that even a validated cleaning method using certified agents can lead to the presence of atypical microorganisms that exceed GMP limits.

  • Challenges in the root cause analysis
  • Integration of new disinfection methods
  • Semi-automatic-disinfecting systems to eliminate Aspergillus Niger in grade A and C clean rooms
