What’s the FFU for Cleanroom?
FFU stands for Fan Filter Unit, and it is a critical component used in cleanrooms to maintain cleanliness and control airborne contaminants. An FFU is a self-contained device that combines a fan and a filter into a single unit. Its primary function is to draw in ambient air, filter it through high-quality filters, and supply clean and filtered air evenly throughout the cleanroom space.
The FFU plays a crucial role in achieving and sustaining the desired air quality levels in cleanrooms. By continuously supplying clean air, it helps prevent the accumulation of particles, microbes, and other airborne contaminants that can compromise sensitive processes, products, or research outcomes. The filtered air is distributed uniformly, ensuring a controlled environment and minimizing the risk of localized contamination.
