Laminar Flow Hood Fan Filter Unit (FFU)

Product Overview

FFU (Fan Filter Unit) is a modular air purification device designed for high-cleanliness environments. The 1175×575mm（2*4ft）model integrates HEPA filters, high-efficiency fans, and intelligent control systems to deliver stable laminar airflow (0.45 m/s ±20%). Its compact design ensures seamless integration into ceiling keel systems while maintaining ultra-low noise levels (<60 dB). Suitable for ISO Class 1-1000 cleanrooms, this unit excels in particle removal and airflow uniformity, making it ideal for industries requiring stringent contamination control.
