Technical Data

FFU (Fan Filter Unit) is a high-efficiency air purification device that integrates a fan and a filtration system, primarily used to provide clean air environments. Below are its key aspects:

1. Definition and Functions

• ‌Basic Definition‌: FFU stands for Fan Filter Unit. It is a self-powered, modular terminal air supply device that draws in air through a fan, filters it through multiple stages, and outputs clean air at a uniform airflow velocity‌
• ‌Core Function‌: Removes particulate pollutants from the air using advanced filtration technologies (e.g., HEPA/ULPA filters) to maintain high cleanliness levels in localized or entire environments‌

2. Structural Components

FFU typically includes the following core components:

1. ‌Fan‌: Drives air circulation to ensure stable airflow‌
2. ‌Filtration System‌: Includes a primary filter (to trap large particles) and a high-efficiency/ultra-high-efficiency filter (HEPA/ULPA, capturing particles ≥0.3μm)‌
3. ‌Housing‌: Modular design (e.g., top cover, side panels, slots) for easy installation and maintenance‌
4. ‌Control System‌: Advanced models feature automatic airflow adjustment via frequency converters to maintain consistent cleanliness‌

3. Applications

FFU is widely used in environments requiring stringent air purity:

• ‌Industrial Production‌: Cleanrooms for semiconductor manufacturing, precision electronics assembly, and pharmaceutical production‌
• ‌Medical and Research‌: Hospital operating rooms, biological labs, and sterile drug preparation areas‌
• ‌Specialized Scenarios‌: Clean benches, modular cleanrooms, data centers, and other localized high-cleanliness zones‌

4. Key Advantages

1. ‌Flexibility and Scalability‌: Modular design allows rapid installation, relocation, or expansion to suit diverse spatial needs‌
2. ‌Cost Efficiency‌: Reduced manufacturing costs with modular housing, low maintenance expenses, and shortened construction cycles due to minimal ductwork‌
3. ‌Energy Optimization‌: Frequency conversion technology enables demand-based airflow, lowering energy consumption‌
4. ‌Space Efficiency‌: Compact structure minimizes vertical space usage, ideal for height-constrained areas‌

5. Technological Trends

Recent advancements focus on ‌intelligent control systems‌ (e.g., automatic airflow adjustment‌2) and ‌structural design optimizations‌ (e.g., modular housings to reduce production costs‌1), enhancing FFU’s stability and adaptability.
