A Fan Filter Unit (FFU) with a diffuser plate is an integrated cleanroom terminal air supply device that combines high-efficiency filtration with airflow homogenization. Its core structure and working principle are as follows:
Key Components
Housing & Fan
Constructed from galvanized aluminum-zinc steel, stainless steel, or aluminum alloy.
Equipped with a centrifugal fan for airflow generation, available in AC/DC power options.
High-Efficiency Filter (HEPA/ULPA)
Filtration efficiency ≥99.99% for 0.3μm particles.
Some models use liquid-sealed designs for enhanced airtightness.
Diffuser Plate (Air Distribution Plate)
Typically made of powder-coated aluminum or stainless steel.
Installed at the outlet to ensure uniform airflow distribution (0.45 m/s ±20%), reducing turbulence and noise.
Applications
Semiconductor/Electronics Industry: Used in ISO Class 3-9 cleanrooms (Class 1 to million-level).
Biopharmaceutical: Achieves localized Class 100 cleanliness when used with laminar flow hoods.
Food/Cosmetics: Meets ISO Class 8 (100,000-level) cleanroom requirements.
Advantages
Modular Design: Allows multiple units to be connected for different room sizes and ceiling heights.
Low Maintenance: Diffuser plates are removable for cleaning, and filters are easy to replace.
