1175*575*320 mm FFU Fan Filter Unit Air Purification Device for Air Improvement 110V/120V 50HZ/60HZ

Technical Data

FFU (Fan Filter Unit)

FFU refers to a self-powered modular air purification device that integrates fans and filtration systems to achieve high-efficiency air cleaning. It is widely used in industries, healthcare, and research fields requiring strict cleanliness standards‌12.

1. Basic Components

FFU primarily consists of:

• ‌Frame‌: Made of galvanized aluminum alloy or stainless steel for structural support‌15;
• ‌Fan System‌: Includes AC or DC motors, with DC models featuring smart control chips for remote operation‌16;
• ‌Filtration System‌: Combines primary filters and HEPA/ULPA filters (efficiency ≥99.99%)‌47;
• ‌Control Modules‌: AC models use speed regulators, while DC models enable network control via gateways‌16.

2. Working Principle

1. ‌Air Intake‌: Fans generate negative pressure to draw external air from the top‌15;
2. ‌Multi-stage Filtration‌: Air passes through primary filters (trapping large particles) and HEPA filters (removing particles ≥0.3μm)‌46;
3. ‌Clean Air Output‌: Purified air is vertically discharged at 0.45m/s±20% to create a unidirectional clean airflow‌28.

3. Key Advantages

• ‌Modularity‌: Flexible configurations for diverse spatial requirements‌45;
• ‌Energy Efficiency‌: DC systems reduce power consumption by 30–50% compared to traditional cleanrooms‌16;
• ‌Rapid Deployment‌: Eliminates complex ductwork, shortening installation time by ≥50%‌58;
• ‌Easy Maintenance‌: Filter replacement without system shutdown‌47.

4. Applications

Modern FFUs support IoT integration for real-time monitoring (airflow, pressure, filter lifespan) and interoperability with building management systems (BMS)‌
