The FFU Fan Filter Unit is a modular air purification device with its own power and integrated high-efficiency filter, widely used in environments with strict air cleanliness requirements.
Key Definition Points
Full Chinese Name: Fan Filter Unit (also called fan filter module or fan filter unit)
English Abbreviation: FFU (Fan Filter Unit)
Core Function: Air is drawn in from the top by the built-in fan and purified in two stages through a pre-filter + high-efficiency (HEPA) or ultra-low penetration (ULPA) filter, then delivered as clean laminar airflow at a velocity of 0.45 m/s ± 20%.
Structural Features: Modular design, can be used individually or in combination with multiple units, supports various installation methods such as ceiling embedding or suspension.
Applicable Cleanliness Class: Can meet cleanliness requirements ranging from ISO Class 10 (100,000 level) to ISO Class 1 (Class 100 or even higher).
Typical Application Scenarios
Semiconductor manufacturing (e.g., SMIC 14nm/28nm production lines)
Biopharmaceuticals, medical device production
Hospital operating rooms, laboratories
Electronic cleanrooms, clean benches, clean booths, etc.
