modular cleanroom design Cleanliness levels from ISO Class 3 (Class A) to ISO Class 8 (Class 100,000)

Covering Core Technical Features, Implementation Processes, and Industry Applications

I. Core Technical Features

1. ‌Modular Structural Design‌

   • Main framework, envelope systems, and purification equipment (FFUs/air showers, etc.) are pre-fabricated as standardized modules, enabling flexible assembly and expansion.
   • Material reuse rate reaches 98%; only consumables like sealants require replacement during relocation or renovation.
   • Features large double-glazed viewing windows with high transparency and airtightness (dual-layer foam-sealed adhesive bonding).

2. ‌Intelligent Environmental Control‌

   • 10-inch touchscreen integrated control system provides real-time monitoring of temperature, humidity, differential pressure, cleanliness, etc., with remote control via mobile/PC.
   • DC-motor FFU units reduce energy consumption by over 60%, with an additional 9% saving in standby mode.
   • Employs "dual HEPA + UV sterilization" exhaust technology to ensure emission safety (e.g., in biopharma labs).

3. ‌Construction Efficiency Advantages‌

   • Factory-preassembled components (doors, windows, air outlets, etc.) enable on-site installation in only 3–5 days, 30% faster than traditional construction.
   • Eliminates on-site cutting, minimizing construction contamination.

II. Implementation Process & Standards

1. ‌Construction Workflow‌

   • Site measurement → framework assembly → flooring → equipment installation → electrical setup → performance validation.
   • Acceptance requires 3 consecutive days of viable particle monitoring (e.g., ≤1 cfu/m³ for Grade A zones).

2. ‌Cleanliness Control‌

   • Cleanliness levels from ISO Class 3 (Class A) to ISO Class 8 (Class 100,000), adjusted via FFU coverage (100% coverage for ISO Class 5) and air-change rates.
   • Precision humidity control (e.g., 45% ±5% for biopharma applications).

3. ‌Material Specifications‌

   • Framework: Aluminum profiles / electrostatic-sprayed square steel tubes / SUS304 stainless steel (anti-static, corrosion-resistant).
   • Envelope: Baked-paint steel plates or stainless steel plates; flooring uses epoxy resin/PVC.

III. Application Scenarios & Case Studies

• ‌Biopharmaceuticals‌: Solved high-humidity contamination during monsoon season for a Wuhu-based pharmaceutical plant, complying with Technical Code for Biosafety Laboratories.
• ‌Semiconductors/Electronics‌: Supports ISO Class 3 cleanliness requirements and micro-environment control for vibration-sensitive equipment (e.g., EUV lithography machines).
• ‌New Energy/R&D‌: Rapid-deployment solutions for EV battery workshops and university labs, ideal for small-scale (<500 m²), high-flexibility needs.
