Four Fundamental Principles for Clean Room Construction

Clean room construction is a comprehensive, integrated multi-functional project. First and foremost, it requires interdisciplinary collaboration across fields including architecture, electrical engineering, HVAC, air purification, and pure water systems. Secondly, it demands precise control over a range of technical parameters such as air cleanliness, bacterial concentration, air volume, pressure, noise level, and illumination level.

During the construction of a clean room, only professional teams can achieve optimal control of all required parameters through integrated coordination of interdisciplinary work. This makes the construction phase a critical part of the entire project. Adhering to the core fundamental principles below is essential to ensure the smooth completion and standard operation of a clean room.

Four Fundamental Principles for Clean Room Construction

1. Prevent Ingress

Prevent any external dust from entering the clean room. The following requirements must be strictly met:A. HEPA filters shall form a dust-tight seal with the building structure to eliminate dust leakage.B. Maintain stable positive pressure inside the clean room at all times.C. Personnel are only allowed to enter the clean room after changing into clean garments and shoes and undergoing air shower treatment.D. All materials and equipment must be thoroughly cleaned before being brought into the clean room.

2. Prevent Generation

Eliminate internal dust generation within the clean room. The following requirements must be strictly met:A. All personnel in the clean room must wear standard clean room garments at all times.B. Avoid using any dust-generating materials and equipment in the clean room.C. Minimize unnecessary movement of personnel and equipment inside the clean room.D. No non-essential items are permitted to be brought into the clean room.

3. Prevent Accumulation

Prevent dust accumulation in any area of the clean room. The following requirements must be strictly met:A. Design equipment and their surrounding areas to facilitate easy cleaning and eliminate hard-to-clean corners.B. Conceal air ducts and pipelines as much as possible to avoid dust accumulation on exposed surfaces.C. All staff must strictly adhere to standardized clean room operating and maintenance procedures.

4. Rapid Removal

Rapidly remove any dust particles generated inside the clean room. The following measures must be implemented:A. Increase the air change rate to enhance air circulation and dust dilution.B. Install dedicated exhaust devices in close proximity to internal dust-generating sources.C. Adopt an appropriate airflow pattern to guide dust particles to air return outlets and prevent dust from adhering to products.
