Custom Cleaning Level Class Modular Cleanroom With Ceiling FFU Air Condition Filtration System

Key Characteristics of Cleanrooms

1. Controlled Air Quality:

   • Airborne particle levels are strictly regulated based on cleanroom classification standards (e.g., ISO 14644 or Federal Standard 209E).
   • HEPA or ULPA filters are commonly used to remove particles as small as 0.3 microns or smaller.

2. Positive Air Pressure:

   • Cleanrooms often maintain higher air pressure inside to prevent unfiltered air from entering when doors are opened.

3. Temperature and Humidity Control:

   • Precise control of temperature (typically 20–22°C) and relative humidity (30–60%) to ensure optimal conditions for sensitive processes and equipment.

4. Airflow System:

   • Laminar airflow (unidirectional) or turbulent airflow systems maintain cleanliness by continuously replacing and filtering air.
   • High air exchange rates, typically 10–600 air changes per hour, depending on the cleanroom classification.

5. Surface Materials:

   • Interior surfaces, including walls, floors, and ceilings, are smooth, non-porous, and easy to clean to minimize particle accumulation.
   • Common materials include epoxy, stainless steel, or special-grade plastics.

6. Personnel Protocols:

   • Workers are required to wear specialized clothing, such as cleanroom suits, gloves, masks, and booties, to minimize contamination from skin or clothing particles.
   • Strict entry and exit protocols, often through airlocks or cleanroom pass boxes.

7. Classification Standards:

   • Cleanrooms are categorized by the allowable number of particles per cubic meter of air. For example:
     • ISO Class 1: Strictest (least particles allowed)
     • ISO Class 9: Least strict (most particles allowed)

8. Monitoring Systems:

   • Continuous monitoring of particle levels, airflow, pressure differentials, and environmental conditions to ensure compliance with cleanroom standards.

Applications of Cleanrooms

• Pharmaceuticals and Biotechnology: To prevent microbial contamination during drug production.
• Semiconductor Manufacturing: To avoid defects caused by dust or other particles on microchips.
• Aerospace: For assembling sensitive equipment like satellites or spacecraft.
• Medical Device Manufacturing: To ensure sterility and compliance with health regulations.

Advantages of Cleanrooms

• Enhanced product quality and consistency.
• Compliance with regulatory standards in critical industries.
• Protection of sensitive processes and equipment from contamination.

Cleanrooms are a cornerstone of modern high-tech manufacturing and research, ensuring optimal conditions for innovation and safety.
