A Cleanroom Laminar Flow Hood is an air purification device used to provide localized high-cleanliness environments. Its primary function is to create Class 100 (ISO Class 5) clean work zones at specific process points. Key features and functions include:
I. Core Structure & Working Principle
Components
Housing (Aluzinc-coated steel/stainless steel, thickness ~20-29cm), Fan (Energy-saving multi-bladed turbo fan, Italy imported), HEPA Filter (Filtration efficiency ≥99.99%@≥0.5μm), Damper layer for pressure equalization, and Lighting.
Fan features 3-speed adjustment with >60,000 hours service life and noise level ≤62 dB(A).
Airflow Control
Air is pressurized by the fan, purified through the HEPA filter, and forms vertical/horizontal unidirectional laminar airflow to prevent contaminant diffusion.
Cleanliness meets US Federal Standard FS209E Class 100 standards (≤3.5 particles ≥0.5μm per liter in work zone), with adjustable average air velocity of 0.25-0.45 m/s.
II. Installation & Deployment Options
Flexible Installation: Supports ceiling suspension, floor-stand mounting, or mobile use with casters. Can operate as a single unit or be combined into clean production lines/laminar flow zones.
Space Efficiency: Ultra-slim profile (total thickness with filter ≤29cm) and lightweight design (~24-30kg) save space and simplify maintenance.
III. Key Advantages
High Cost Efficiency
Lower investment, shorter construction time, and reduced structural requirements compared to building full cleanrooms, with significant energy savings.
Wide Applications
Suitable for biotechnology/pharmaceuticals (aseptic filling), precision electronics, food processing, fine chemicals, etc.
Can be expanded into clean benches, clean booths, or garment storage units.
IV. Comparison with Cleanrooms
Localized Enhancement: Upgrades critical process points to Class 100 within existing cleanrooms where overall environment is insufficient.
Retrofit Convenience: Ideal for renovation projects in older facilities, requiring minimal structural modifications.
