1175×875 large DC FFU adopts 400mm external rotor fan, dual filtration, 0.8mm aluminum-zinc coated housing and group control module. 1500m³/h high airflow for large cleanroom, semiconductor, pharmaceutical and food clean area projects.
1175×1175 large DC FFU compatible with 1200×1200 cleanroom ceiling grid. Equipped with DC external rotor 400 fan, airflow ≥2000m³/h, 0.8mm aluminized zinc housing for semiconductor, pharmaceutical & food large clean areas.
This FFU (Fan Filter Unit) is an air purification device designed for cleanroom ceiling systems. It integrates a fan and a high-efficiency filter to provide stable laminar airflow. Air is drawn in by the fan, filtered through a high-efficiency filter, and then supplied evenly into the cleanroom.The unit is equipped with a DC 310 external rotor fan, ensuring stable operation, low noise and uniform airflow. The housing is made of 0.8 mm galvanized steel, providing durable and reliable structure. It is widely used in electronics, semiconductor manufacturing, pharmaceutical workshops and laboratories.
