Cleanroom Laminar Flow Hood

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

1. ‌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).

2. ‌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

1. ‌High Cost Efficiency‌
   • Lower investment, shorter construction time, and reduced structural requirements compared to building full cleanrooms, with significant energy savings.
2. ‌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.
