FFU with HEPA filter


Fan Filter Unit can be a self-contained ceiling unit for used turbulent mixing and laminar circulation cleanroom applications. Fan Filter Unit is built to provide filtered laminar airflow spanning a specific area. The unit integrates an increased efficiency fan together your HEPA/ULPA filter. The FFU draws in contaminated air from the top of the module, and exhaust filtered clean air vertically in the laminar air stream from its base. FFU’s are commonly used in the construction of Class 1 to help Class 100, 000 cleanrooms ( down to the US Federal Regular 209E)

We developed FFU is usually from basing upon the actual concepts including, to decrease running cost by saving energy, and to lower initial cost by entire design of clean area; such as noise specification or anything else, to meet all what's needed for constructing, operating, and also maintaining cleanrooms. Our manufacturing capabilities vary from complete computerized sheet metallic design, to fabrication plus assembly. A vertically-integrated approach helps to ensure that quality can be controlled at every step in the way.
