ZJNF Custom Dimension ISO 1-8 Modular Clean Dust Free Room With GMP Standard CE UL Certificates

Cleanroom System Overview

A cleanroom is a controlled environment that minimizes airborne particles, chemical vapors, and other contaminants to meet specific cleanliness standards. It is widely used in semiconductor manufacturing, biotechnology, pharmaceuticals, and precision engineering‌

Core Components

1. ‌Enclosure System‌

   • Constructed with sealed materials like color steel panels or rock wool sandwich panels to prevent dust accumulation.
   • Features airtight doors and double-glazed windows to maintain pressure differentials

2. ‌Air Purification System‌

   • Uses a three-stage filtration (pre-filter, medium-efficiency, HEPA/ULPA) to achieve ISO 14644-1 standards
   • Common configurations: MAU (Make-up Air Unit) + FFU (Fan Filter Unit) + DDC (Dry Cooling Coil) for uniform airflow.

3. ‌Cleanliness Standards (ISO 14644-1)‌

   • Classified from ISO 1 (highest) to ISO 9, based on particle counts per cubic meter (e.g., ISO 5 allows ≤3,520 particles ≥0.5μm)
   • Semiconductor fabs typically require ISO 1-3 for sub-micron processes

4. ‌Auxiliary Systems‌

   • ‌Temperature/Humidity Control‌: Precision air conditioning for stability (e.g., ±0.5°C in electronics)
   • ‌Pressure Control‌: Maintains positive/negative pressure zones to prevent cross-contamination
   • ‌ESD Protection‌: Anti-static flooring and materials for sensitive components‌

     Applications

     • ‌Semiconductors‌: ISO 1-3 for lithography and wafer processing
     • ‌Pharma‌: ISO 5-7 for sterile drug production
     • ‌Biotech‌: ISO 6-8 for cell culture and diagnostics‌
