Diffuser Plate FFU Air Purification For Clean Room Mushroom Growing Equipment

‌Fan Filter Unit (FFU) with Diffuser Plate‌

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

1. ‌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.

2. ‌High-Efficiency Filter (HEPA/ULPA)‌

   • Filtration efficiency ≥99.99% for 0.3μm particles.
   • Some models use liquid-sealed designs for enhanced airtightness.

3. ‌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.
