The combination of FFUs and small compact airconditioning units provides a cost effective, intelligent combination. Instead of using a very
large air-conditioning system that re-conditions
the complete amount of air for the Cleanroom,
we use small and compact air-handlers that are located near the Cleanroom. These small air-con-
ditioning units only condition a portion of the total air-volume whilst the ceiling integrated Fan Filter Units re-circulate the majority of the required air-
volume back to the Cleanroom. This means less ducting and lower investment costs for a larger AC System.

The FFUs maintain the Cleanroom class even in the case of a non-functional air-conditioning system.
