CLEANROOM KNOWLEDGE
Normal room air contains several million particles - per cubic meter! In a GMP Class A cleanroom, there can be a maximum of 3,520 particles ≥ 0.5 µm per cubic meter. What kind of incredibly sophisticated filter technology can achieve this?

The survival guide nobody gives you before your first shift
CLEANROOM KNOWLEDGE
Particles are the natural enemy of any cleanroom – virtually all measures taken in cleanroom technology have just one aim: to reduce their presence to a minimum. But they are not the only adversary
CLEANROOM KNOWLEDGE
Quick test: Ask someone you know if they know what a cleanroom is. Most people will probably say something along the lines of “medicine” and “clean.” How cool would it be if you could just rattle off a smooth explanation right off the top of your head!
Maintenance intervals depend on the type of system, usage, manufacturer requirements, and regulatory guidelines. Based on these factors, an appropriate maintenance plan can be developed. Regular maintenance helps ensure long-term technical availability and the required cleanroom conditions.
Depending on the system, these include, among others, HVAC systems, filter fan units, heating and cooling systems, airflow controllers, fire dampers, measurement and control technology, electrical systems, and airlock control systems.
Any defects found are documented and assessed. We then consult with you to determine which repair or optimization measures are necessary and appropriate.
That depends on the system and the scope of maintenance. Where technically possible, we schedule work to minimize operational disruptions as much as possible. For critical interventions, we coordinate appropriate time windows and measures with you in advance.
Yes. This combination is particularly beneficial for cleanroom systems because technical maintenance measures can affect cleanroom parameters. Maintenance, optimization, and subsequent metrological verification can therefore be coordinated and carried out together.
Yes. For existing systems, we assess which components can be improved from a technical or energy-efficiency standpoint. Modernization can, for example, involve control systems, system components, or operating procedures, and can serve as an alternative to a complete replacement.
The CAT Group supports operators with the maintenance, inspection, repair, and technical service of cleanrooms and building services systems. See for yourself - our references demonstrate how we provide long-term support for systems and ensure reliable and safe operation.
