Domino Laser develops and manufactures UV marking lasers for industrial applications. During the assembly of dust-sensitive laser components, a clear directive came from R&D to production: assembly must be carried out under defined air quality according to ISO 14644-1 Class 7. The company was looking for a solution that reliably met this requirement while also offering flexibility for future layout changes.
Initial Situation
The requirement came directly from the R&D department: the assembly of dust-sensitive components for the UV marking laser needed to be performed under defined air quality in accordance with ISO 14644-1 Class 7. While a conventional fixed cleanroom would have met this requirement, it would have come at the cost of inflexibility and high investment.
Solution
Domino Laser chose a cleanroom tent from Nordair Systems. Kai Krohn explains the two key factors that influenced this decision: the flexibility of the solution and the quality of the consultation compared to competitors.
"No permanent fixture. The flexibility to move the unit with little effort during future layout changes. Expansions are also very easy."
The modular principle ensures the required cleanliness class without tying production to a rigid structural design.
"Fast and excellent on-site consultation. That's where Nordair truly stood out from the competition."
Result
The system's functionality was verified immediately after installation:
"Immediately after the assembly tables were moved in and all surfaces were cleaned, the permissible particle limits fell below the required levels. The system is capable of ensuring the required Class 7."
During ongoing operations, the team is currently developing a procedural instruction for behavior within the cleanroom to permanently keep the particle load caused by employees below the limit values. This is the typical transition from structural qualification to established cleanroom operation.
