FFU(Fan Filter Units)


Fan Filter Unit(FFU)

Fan Filter Unit(FFU) is air cleaner equipment to purify air?in the clean room for manufacturing semiconductor , liquid crystal, etc. The installation space is the system ceiling grid. For a large clean room, the number of required FFU is from several hundreds to several thousands.


1. To reduce operating cost by saving energy
2. To reduce construction cost and term by thin, light and compact structure
3. To reduce initial cost by total design of clean room including noise spec.etc

?FFU units based upon the above concepts ?to meet all the requirements for constructing, operating and maintaining clean rooms.
