Product Details
Modular Control FFU Laminar Flow Hood Cleanroom Air Cleaning Equipment Pre-Filter HEPA Filter Ventilation System New




It's composed of a casing, a fan, a HEPA/ULPA filter, and a control system. The built – in fan sucks in air, which then passes through the pre – filter and the hepa filter. The filtered clean air is evenly delivered across the outlet surface at a wind speed of 0.45m/s ± 20%. This process effectively removes particles and microorganisms in the air, ensuring high – quality air in the workspace.
FFUs are widely used in cleanrooms, laminar flow cabinets, and other areas with strict air – cleanliness requirements, such as semiconductor manufacturing, hospitals, and laboratories. Their modular design allows for easy installation, replacement, and scalability, adapting to different room sizes and cleanliness levels. Plus, they are energy – efficient and can operate with low noise, making them a popular choice for creating clean environments.
