In an ISO 8 modular cleanroom, effective airflow management is crucial to maintaining the required cleanliness levels and ensuring a safe working environment. While ISO 8 cleanrooms do not have as strict particle limits as ISO 7 cleanrooms, controlling airflow is still essential for minimizing contamination and providing a stable environment for various applications.

Key Features of Airflow in ISO 8 Cleanrooms

Air Changes per Hour (ACH)

ISO 8 cleanrooms typically require a minimum of 20 to 40 air changes per hour. This ensures that any contaminants introduced into the cleanroom are quickly diluted and removed.

The exact number of air changes may vary based on the specific processes being conducted and the layout of the cleanroom.

Return Air System

Effective return air systems help recirculate air back to the filtration units, ensuring that the cleanroom maintains its cleanliness standards. The design of the return air pathways is important to avoid dead zones where contaminants could accumulate.

Importance of testing

Clean room testing is extremely important to ensure product quality and the stability of the production environment. It can help to confirm whether the clean room meets the intended cleanliness requirements, and whether the various environmental indicators comply with the specified standards.

Testing Items

• Suspended particles: Detects the number of suspended particles in the air in the clean room to ensure that the air cleanliness is up to standard.

• Temperature and humidity: Monitor the temperature and humidity in the clean room to ensure environmental stability during the production process.

• Noise: Evaluates the noise level in the clean room to minimize the impact on staff.

• Static electricity: Detect static electricity buildup in the clean room to prevent damage to sensitive components from electrostatic discharge.

• Microbial contamination: Detecting microbial levels in the clean room, especially critical for the healthcare industry.
