ISO9001 Certified fan filter unit,4x2 feet Fan Filter Unit,Cleanroom FFU,Fan Filter Unit
Our factory have been the membership of “Onsite Checked”
FFU, short for Fan Filter Unit, which draws in contaminated air from the top of the module, and exhausts filtered clean air vertically in a unidirectional(laminar) air stream at its base, is a self-contained fan and filter module for cleanroom applications.
FFU provides clean air and particle controlling. FFU is installed on ceiling of clean room (25% to100% cover rate), general dimension is 2' * 4' or 4' * 4'.
Application: FFU's are commonly used in the construction of Class 1 to Class 100,000 cleanrooms, even forming ultra clean line, clean closet and etc...
