When designing the airflow system for an ISO 7 modular cleanroom, several factors must be considered:

Air Changes Per Hour (ACH):

• ISO Class 7 cleanrooms typically require 30-50 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 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 a modular cleanroom?

A modular cleanroom is a prefabricated, adaptable space designed to meet specific cleanliness standards. It can be quickly assembled and customized for various applications.

What role does lighting play in cleanrooms?

Lighting in cleanrooms is crucial for visibility and safety. It must be designed to minimize shadows and glare while maintaining cleanliness. Proper lighting enhances operational efficiency and worker comfort.

What is the cleanroom certification process?

3. Air filtration units to maintain air quality.
   These components work together to create a controlled environment.

What is the role of pressure differentials in cleanrooms?

Pressure differentials in cleanrooms help control airflow and prevent contamination. Higher pressure inside the cleanroom compared to adjacent areas ensures that air flows outward, minimizing the ingress of contaminants.

How do you measure cleanroom performance?

Cleanroom performance can be measured using various methods:

1. Monitoring particle counts with laser particle counters.
2. Assessing airflow rates and patterns.
3. Evaluating temperature and humidity levels.
   These measurements ensure compliance with cleanliness standards.

What is the difference between modular and traditional cleanrooms?

Modular cleanrooms are prefabricated and allow for quick installation and reconfiguration. Traditional cleanrooms are built on-site, requiring more time and resources. Modular designs offer greater flexibility and scalability.

How to manage personnel in a cleanroom?

Managing personnel in a cleanroom involves:

1. Implementing strict gowning and hygiene protocols.
2. Conducting regular training on cleanroom procedures.
3. Monitoring activities to ensure compliance with operational guidelines.
   These practices help maintain a contaminant-free environment.

How to implement a cleanroom training program?

To implement a cleanroom training program:

1. Develop training materials covering protocols and procedures.
2. Schedule initial and ongoing training sessions for all personnel.
3. Assess understanding through evaluations and practical exercises.
   This ensures staff are well-prepared for cleanroom operations.

How to integrate HVAC systems in modular cleanrooms?

Integrating HVAC systems in modular cleanrooms requires:

1. Designing the system to provide adequate airflow and filtration.
