Considerations for ISO Class 5 Cleanrooms

As ISO Class 5 cleanrooms are at the more critical end of the class spectrum, they require a greater level of filtration to achieve the level of cleanliness.

Ultra Low Penetration Air (ULPA) Filtration is 99.9995% efficient at 0.12 micron and should be considered when looking to achieve ISO class 5.

Monobloc construction cleanroomHardwall and monobloc cleanroom constructions are most effective at achieving the environment required for ISO class 5.

If organisations are working towards GMP grades, monobloc is the most effective solution, as it can accommodate required features such as interlocked doors and coved floors.

See our Case Studies for more information.
