Here is the professional English translation of the layered ultra-clean workbench description:

‌Laminar Flow Clean Bench‌
A laminar flow clean bench utilizes a high-efficiency air filtration system to generate unidirectional airflow (vertical or horizontal), creating a localized high-cleanliness operating environment. Its core function is to protect samples from contamination. Key features and applications are as follows:

I. Core Principles & Structure

1. ‌Laminar Flow Mechanism‌
   Room air is pre-purified by a primary filter, pressurized into a plenum chamber via a blower, and then filtered through a HEPA filter to form stable unidirectional airflow (vertical or horizontal)
   • ‌Vertical Laminar Flow‌: Top-down airflow prevents direct exposure to operators; ideal for high-risk biomedical applications
   • ‌Horizontal Laminar Flow‌: Horizontal outward airflow offers larger workspace; commonly used in electronics
2. ‌Cleanliness Class‌
   Work zone achieves Class 100 (ISO Class 5) cleanliness: ≤3.52 particles (≥0.5μm) per liter
3. ‌Core Components‌
   Include primary/HEPA filters, blower, stainless steel work surface, UV germicidal lamp, and smart control system (e.g., touchscreen for wind speed adjustment)

II. Classification & Selection

III. Primary Applications

• ‌Biomedicine‌: Cell culture, vaccine preparation, aseptic preparation filling (contamination rate <0.8%)
• ‌Medical Testing‌: Virus isolation, nucleic acid detection (prevents aerosol contamination)
• ‌Precision Manufacturing‌: Electronic component assembly, optical instrument production (anti-dust/anti-static)
• ‌Food & Research‌: Microbial testing, gene editing (e.g., CRISPR), ensures experimental accuracy

IV. Operation & Maintenance Guidelines

1. ‌Environmental Requirements‌
   Temperature: 5–35°C; humidity ≤85%; avoid dusty/explosive environments
2. ‌Safe Operation‌
   • Sterilize with UV light for 30 mins before use; keep glass sash partially closed during operation
   • Regularly monitor wind speed (0.3–0.6m/s for vertical flow) and filter pressure differential
3. ‌Maintenance Cycle‌
   • Clean primary filter monthly; replace HEPA filter every 2–3 years (varies by environment)
   • Equipment lifespan correlates with air cleanliness; shorter intervals in tropical regions

V. Technology Evolution

Modern models (e.g., VD-650) feature smart controls for stepless wind speed adjustment and real-time pressure display; DC motors reduce energy consumption by 30%, while stainless steel enhances corrosion resistance. High-end units include dynamic airflow monitoring to limit speed fluctuations to ≤20%
