A cleanroom should be clean. Clearly. And to keep it clean, it should be airtight. Also clear. However, cleanliness and airtightness are topics that so far have been considered as "included" by builders and clients. Actually, rightly so. But unfortunately, numerous airtightness tests on existing cleanrooms have revealed an extremely high leakage rate. For example, nearly 300 measurements conducted by Dipl.-Ing. Daniel Jung (jung-gbw mbh/Hildesheim) showed that existing limit values – for instance, for air exchange rate – are not met during the planning and construction of cleanrooms, even in hospitals, laboratories, and other medical facilities.

This more than unsatisfactory situation prompted standards committees to act, and so, since this year, there is the new standard VDI 2083/19, which normatively describes the airtightness of cleanrooms and has already caused quite a stir in the industry during its development. This new standard not only demands compliance from cleanroom suppliers but also takes a holistic approach that extends much further. As a result, countless operators of facilities, especially hospitals and hygiene specialists, will need to address the issue of airtightness more closely in the near future.

On this current occasion, the company BlowerDoor is offering a seminar on January 18/19, 2018, in Mannheim titled "Airtightness of Cleanrooms – Classification, Planning, and Testing," which will thoroughly examine the content and implications of the new standard. Especially planners, builders, users, and quality inspectors of cleanrooms will have the opportunity here to clarify questions, overcome uncertainties, and learn about the background of the new standard in an objective manner. Additional topics of the two-day seminar include selecting the appropriate room airtightness classes for specific applications and the corresponding recommendations for planning and executing the cleanroom envelope. Furthermore, participants will conduct an intensive, practical demonstration of the testing process, including leak detection, and will ultimately prepare a test report.

The content listed on BlowerDoor's website, especially the list of speakers, indicates that participants will gain a great deal from these two days, not just a well-filled conference folder. The registration deadline for this undoubtedly enriching event is December 12, 2017.
