Skip maintenance? That’s risky.

Maintenance keeps cleanroom technology running smoothly, inspection keeps a critical eye on it, and repairs clean up the mess when something does go wrong – that’s a casual way to describe it.

A slightly more detailed definition goes like this:

Maintenance in cleanroom technology encompasses all preventive measures taken to maintain the operational readiness of the systems, filtration and HVAC equipment, and the cleanroom enclosure. This includes, among other things, replacing filters, cleaning certain components, and inspecting technical components.

During an inspection, the current condition of a cleanroom and its technical systems is determined and evaluated. For example, whether ventilation systems, filters, seals, or measuring devices are functioning properly. This allows for the early detection of wear and tear or potential malfunctions.

Repair is necessary when a defect or damage has already been identified. It essentially refers to the entirety of measures taken to restore the system to its functional and standard-compliant target state following a failure, damage, or even an impermissible deviation.

And how often does a cleanroom need to be maintained?
That depends on the type of facility, its use, the manufacturer’s requirements, and regulatory guidelines. Based on this information, a suitable maintenance plan can be developed.
