Product Description
Fan Filter Unit is a self-contained ceiling unit for use in turbulent mixing and laminar flow cleanroom applications. Fan Filter Unit is designed to provide filtered laminar airflow over a specific area. The unit integrates a high efficiency fan together a HEPA/ULPA filter. The FFU draws in contaminated air from the top of the module, and exhaust filtered clean air vertically in a laminar air stream at its base. FFU’s are commonly used in the construction of Class 1 to Class 100,000 cleanrooms ( as per the US Federal Standard 209E)
We developed FFU is from basing upon the concepts including, to reduce running cost by saving energy, and to reduce initial cost by total design of clean room; such as noise specification etc, to meet all the requirements for constructing, operating, and maintaining cleanrooms. Our manufacturing capabilities range from complete computerized sheet metal design, to fabrication and assembly. A vertically-integrated approach ensures that quality can be controlled at every step of the way.
Product Characteristics
• Permanently lubricated, direct-drive centrifugal blower.
• Light weight, corrosion-resistant construction
• Wide range of ceiling grid system compatible
• Integral metal faceguard protects the HEPA/ULPA filter from damage during installation and transportation.
• Fan inlet guard grille ensure operator safety during installation and prevents large objects from falling into the casing and damaging the blower
• Pre Filter available on request
