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
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
Cleanliness Class Work zone achieves Class 100 (ISO Class 5) cleanliness: ≤3.52 particles (≥0.5μm) per liter
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
Classification Basis
Type
Characteristics
Airflow Direction
Vertical Laminar Flow
Top-down airflow; high operator safety; suitable for biological labs
Horizontal Laminar Flow
Larger workspace; lower noise; preferred in electronics
Operation Structure
Single-person single-side
Single blower; lower noise
Dual-person single-side
Dual blowers; moderate noise increase
Dual-person dual-side
Enables collaboration; requires larger space
Special Designs
Recirculating Type
No external ducts; flexible deployment in non-clean areas
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
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%
