I. Core Design Process

1. ‌Requirement Planning & Spatial Layout‌

   • Define cleanliness class (ISO Class 3 to Class 8) and temperature/humidity precision (±0.1°C/±1% RH)
   • Zone functional areas: personnel purification (air showers), material transfer (pass-through windows), core production zones; optimize personnel/material flows to prevent cross-contamination
   • Reserve equipment interfaces: pre-plan equipment locations, electrical conduits, and control system wiring

2. ‌Structural System Design‌

   • ‌Framework Selection‌: Aluminum profiles (lightweight) or SUS304 stainless steel (corrosion-resistant) with electrostatic anti-dust coating
   • ‌Enclosure System‌:
     • Walls: Powder-coated steel/stainless steel panels with sealed joints (Class 100 zones require R50mm curved corners to prevent dust accumulation)
     • Viewing windows: Double-glazed tempered glass for visibility and airtightness
   • ‌Floor Treatment‌: Epoxy resin/PVC flooring (chemical-resistant, anti-slip); raised floor return air systems for high-cleanliness zones

3. ‌Aerodynamic Configuration‌

   ‌Element‌	‌Technical Requirements‌
   ‌FFU Layout‌	100% ceiling coverage for Class 100 zones; Class 10,000 zones require ≥25 air changes/hour
   ‌Filtration System‌	HEPA+ULPA combination (efficiency ≥99.99%@0.3μm); UV sterilization for Grade A/B zones
   ‌Pressure Control‌	Maintain 10–15Pa gradients (highest positive pressure in core zones) with smart dampers

4. ‌Smart Control System‌

   • 10-inch touchscreen for real-time monitoring of particle count/temperature/humidity/pressure with threshold alarms
   • IoT platform for remote adjustment of HVAC/lighting/FFU speed, reducing energy consumption by 20–30% vs. traditional systems

II. Key Construction Specifications

1. ‌Factory Prefabrication Stage‌

   • Dust-free production of modular components (wall panels/FFUs/piping) with pre-installed electrical interfaces
   • Strict QC: Air-tightness testing (≤0.01% leakage rate), material corrosion resistance verification

2. ‌On-Site Installation Essentials‌

   • Foundation preparation: Floor flatness tolerance ≤2mm/2m with moisture barrier
   • Building-block assembly:

     Non-disruptive construction: No on-site cutting permitted; 500 m² basic module assembly within 48 hours
     

3. ‌Validation Standards‌

   • Dynamic testing: Continuous 72-hour viable particle monitoring (≤1 cfu/m³ for ISO Class 5 zones)
   • Airflow visualization: Smoke tests to confirm ≤0.1% dead zones
