A high-efficiency FFU (Fan Filter Unit) is a self-powered, modular air supply terminal unit with high-efficiency filtration, widely used in environments requiring extremely high air cleanliness. Its core functions and working principles are as follows:
High-Efficiency Filtration
FFUs are typically equipped with HEPA or ULPA high-efficiency filters, achieving filtration efficiency levels of H13/H14 (99.97%+ for 0.3-micron particles). Some models support multi-stage filtration (e.g., pre-filter + HEPA + activated carbon) to address dust, chemical pollutants, etc.
Intelligent Control
Energy Efficiency & Low Noise
FFUs draw air from the top, filter it through high-efficiency filters, and deliver clean laminar airflow at a uniform speed of 0.45 m/s ±20%, creating a localized unidirectional clean zone. Their modular design allows flexible assembly to meet varying cleanliness requirements (e.g., Class 100, 1000 cleanrooms).
