Which fog fluid is suitable for flow visualization according to GMP Annex 1?

The perfect fog fluid still does not exist. Pharmaceutical companies that perform or have performed airflow visualizations in critical cleanroom areas will find in this white paper comprehensive information to select the appropriate fog fluid for the specific application. A comparison between fog an…

The lifting jacks from EAP Lachnit provide a secure stance and enable risk-free work on machines, systems, and even under low hall ceilings. (Image: EAP Lachnit GmbH)

The lifting platform is electrically operated and does not require oil hydraulics; the lifting height ranges from 400 to 2,000 mm. (Image: EAP Lachnit GmbH)

The lifting platform is equipped with a bellows that serves as a clamping protection for the scissors and protects both people and machinery. (Image: EAP Lachnit GmbH)

The operation of the lifting platform is very simple and intuitive: a handheld switch allows for raising or lowering, and for safety, a

Since even the tiniest dust particles and residual manufacturing debris can impair satellite performance, extremely high cleanliness standards must be met. (Image source: OHB System)

For the cleaning of the CFRP structures of satellites – here with integrated cable harness and thermal components – OHB System and acp have designed a solution that allows for cleanliness verification during the cleaning process. (Photo credit: OHB System)

Thanks to the two laser pointers integrated into the nozzle head, the optimal distance from the inner surfaces to be cleaned can be set. (Photo credit: OHB System)

The baffle is placed on the fork of the cleaning machine by crane. An integrated camera system in the nozzle head displays the entire cleaning process live on the monitor. (Image source: acp systems)

The swiveling nozzle head is mounted on a lance, through the openings of which the removed contaminants are suctioned away. The cleanliness verification is carried out using a particle counter integrated into the exhaust air stream. (Image source: acp Systems)
