In ISO 6 softwall cleanrooms, the airflow principle is crucial for maintaining cleanliness and controlling contamination. The following key elements describe this principle:

• Unidirectional Flow: Clean air is supplied in a single direction from the ceiling to the floor, minimizing turbulence and particulate disturbance.

• HEPA Filtration: High-Efficiency Particulate Air (HEPA) filters remove contaminants from the air before it enters the cleanroom, ensuring a high level of air purity.

• Positive Pressure: The cleanroom is maintained at a higher pressure compared to adjacent areas, preventing outside contaminants from infiltrating the space.

• Air Changes Per Hour (ACH): A specified number of air changes per hour is maintained to dilute and remove airborne particles, keeping the environment compliant with ISO 6 standards.

• Return Air Systems: Air is usually returned through vents located at the bottom, facilitating proper circulation and ensuring uniform airflow throughout the cleanroom.

ISO 6 Softwall Cleanrooms Installation Steps

• Site Preparation: Evaluate the installation area for dimensions and utility access. Ensure the space meets cleanroom requirements.

• Framework Assembly: Assemble the cleanroom framework, including support structures and flexible wall panels designed for easy maintenance.

• Component Installation: Install essential components such as HEPA filters, lighting, and airflow systems to ensure compliance with ISO 6 standards.

• Testing and Verification: Conduct rigorous testing of airflow, particle counts, and overall performance to confirm the cleanroom meets ISO 6 cleanliness requirements.

• Staff Training: Train personnel on operating procedures and maintenance protocols to ensure effective cleanroom operation.

ISO 6 softwall cleanroom testing is essential to ensure that the environment meets the required cleanliness standards and operates effectively. Below are the key aspects of testing and features associated with ISO 6 softwall cleanrooms.

Key Features of ISO 6 Softwall Cleanroom Testing:

Particle Counting:

Regular monitoring of airborne particles to ensure compliance with ISO 6 limits (maximum 3,520 particles per cubic meter for ≥0.5 micrometers).

Airflow and Air Changes:

Assessment of airflow rates and air changes per hour to maintain optimal conditions and prevent contamination.

Temperature and Humidity Control:

Continuous monitoring of temperature and humidity levels to ensure they remain within specified ranges (typically 20°C to 24°C and 30% to 60% humidity).

Pressure Differential Testing:

Verification of pressure differentials between the cleanroom and adjacent areas to prevent contamination ingress.

These testing features are crucial for maintaining the integrity and operational efficiency of ISO 6 softwall cleanrooms, ensuring they provide a suitable environment for sensitive processes.
