When designing the airflow system for an ISO 6 modular cleanroom, several factors must be considered:

Air Changes Per Hour (ACH):

• ISO Class 6 cleanrooms typically require 70-160 air changes per hour to maintain cleanliness.

• The exact number depends on the cleanroom’s size, usage, and contamination sources.

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 Standards

ISO 6 Modular Cleanroom Testing Standards are guided by ISO 14644-1 and related protocols to ensure compliance and performance. Key standards include:

• Particle Count Testing: Verifies airborne particle levels (≤35,200 particles ≥0.5 µm/m³).

• Airflow Velocity Testing: Ensures proper airflow speed and uniformity.

• Filter Integrity Testing: Detects HEPA/ULPA filter leaks using DOP/PAO aerosols.

• Pressure Differential Testing: Maintains positive pressure to prevent contamination.

• Air Changes Per Hour (ACH): Confirms sufficient air replacement (70-160 ACH).

• Recovery Testing: Measures contamination recovery time.

• Environmental Monitoring: Tracks temperature, humidity, lighting, and noise levels.

These standards ensure the cleanroom meets ISO Class 6 requirements for controlled environments.

What is the difference between ISO 6 and ISO 7 cleanrooms?

ISO 6 cleanrooms have stricter cleanliness standards than ISO 7. Specifically, ISO 6 permits a maximum of 1,000 particles per cubic meter, while ISO 7 allows up to 10,000.
Additionally, ISO 6 requires more stringent environmental controls, such as temperature and humidity management, to ensure product integrity. This makes ISO 6 suitable for sensitive applications.
Overall, the choice between ISO 6 and ISO 7 depends on the specific requirements of the processes being conducted.

What is the procurement process for modular cleanrooms?

The procurement process for modular cleanrooms typically involves several key steps. First, assess the project requirements and define specifications based on the intended use.

Adhering to ISO 6 standards also aids in compliance with regulatory requirements set forth by health authorities, ensuring product quality and patient safety.

How to monitor particle counts in an ISO 6 cleanroom?

To monitor particle counts in an ISO 6 cleanroom, use a calibrated laser particle counter. This device provides real-time measurements of airborne particles.
Conduct routine monitoring during different operational phases to assess cleanliness levels continuously. Establish a monitoring schedule based on specific cleanroom activities.
Document all findings and compare them against ISO 6 standards. If counts exceed allowable limits, investigate and implement corrective measures promptly.

Why choose a modular cleanroom over a traditional cleanroom?

Choosing a modular cleanroom offers several advantages over traditional designs. First, modular cleanrooms provide flexibility in design and layout, allowing for easy reconfiguration as needs change.
Second, they typically have faster installation times, reducing downtime and costs associated with construction. Modular systems can be expanded or relocated with relative ease.
Lastly, they often utilize pre-fabricated components, ensuring consistent quality and adherence to cleanliness standards from the outset.

What are the selection criteria for air filters in modular cleanrooms?

When selecting air filters for modular cleanrooms, consider the following criteria:
