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.

What is the process of cleanroom certification?

Cleanroom certification involves several key steps. Initially, a thorough assessment of the cleanroom's design and operational procedures is conducted. Following this, various tests are performed to measure particulate contamination levels.
Finally, an official report is generated, confirming if the cleanroom meets the required standards for classification. The certification process ensures compliance and operational efficiency.
It is essential to periodically re-evaluate and maintain certification to uphold cleanliness standards.

What type of air filtration is needed for an ISO 8 cleanroom?

An ISO 8 cleanroom requires high-efficiency particulate air (HEPA) filters for effective air filtration. These filters capture particles larger than 0.3 microns at a 99.97% efficiency.
In addition to HEPA filters, pre-filters are also used to extend the life of the HEPA filters. It is crucial to monitor the performance of these filters regularly to ensure optimal air quality.
Proper air filtration prevents contamination and maintains the integrity of the cleanroom environment.

What kind of training is required for cleanroom personnel?

Training for cleanroom personnel is vital for maintaining cleanliness and safety. Initial training should cover cleanroom protocols, gowning procedures, and contamination control measures.
Ongoing training is equally important and should focus on safety regulations, equipment handling, and emergency procedures. Regular refreshers help reinforce knowledge and compliance among staff.
Moreover, specialized training may be necessary for specific roles, ensuring all personnel are well-equipped to perform their duties effectively.

What types of pass-through systems are used in cleanrooms?

Pass-through systems are essential for maintaining cleanroom integrity. Common types include:

• Standard pass-throughs: Basic openings for transferring materials.
• Airlock pass-throughs: Systems that minimize contamination risks during transfers.
• Automated pass-throughs: Mechanisms that enhance efficiency and reduce human contact.
  Selecting the right system depends on the cleanroom's requirements and the materials being handled.

How do I train staff for cleanroom environments?
